📍 Air door actuator locations for 1988-94 Chevy/GMC trucks: heater mode selector, heater blend door, and air inlet. Struggling with a faulty actuator? My blog post is the ultimate guide to help you diagnose & repair! 💪🔧 #GMC #TruckRepair 🔗 www.buildpriceoption.com/air-door-actuator-locations-1988-94-chevy-and-gmc-truck/
If you cut the slot where the screw goes on the very end, you can start the screw first then slide the actuator into place, then tighten the screws afterwards.
I was thinking of trying that. Will it let the actuator swing into place on the shaft? UPDATE: You were right after fighting that little bastard all the way out, I screwed it back in about 2/3 and cut a slot in the actuator. A little tricky getting it to line up ( I already had the blower motor removed so, it was easy to lift the door to align the shaft) But, well worth it. Thanks Armando! PS, it also helps if you cuss at it a lot.
SO FYI... the problem with cutting the tab to make it a "slot" is... the actuator fits over the "shaft" of the door AND over the pin of the 3rd hole, and cannot slide into place... it cannot "pivot" either... there just is no room. YOU CAN get a little better tool... a 1/4 hex drive bit that is a "nut-driver" in 9/32 or 5.5mm works... you can cut the shaft of the bit to make it shorter and use the little "shallow" ratchet handle or a 1/4 ratcheting box end wrench on the bit... and a tiny neo-magnet stuck to the back of the bit holds the screw to the bit to reinstall...
After all that work, it would drive me crazy not to have that last screw installed! Come on Frank! Be a hero and get it done. I saw a video and the guy taped the screw to a socket and got it started with his fingers. Then used that 1/4 inch ratchet with the flexible end. Great video and information.
Put the screw through the hole . Slip a small o-ring on the backside holding it in place .Put your actuator in place then tighten the screw. This trick works on various applications. I keep all sizes of o-rings in my toolbox for this very reason . Hope this helps .
I used a 4 1/2” angle grinder to cut an approximately 1 1/2” wide x 3” high opening in the firewall in the engine compartment after taking a bunch of measurements as to where I needed the hole. I didn’t cut the side closest to the center of the vehicle just used it like a hinge. Then bent the little panel open and removed the screw. To close it up I hammered the flap shut and neatly applied a two pieces of silver aluminum tape. Works good, looks ok. This is a 30 year old work truck so no one will be taking pictures of my art work at a car show…
That's how I replaced my AC evaporator. Cut a hole in the firewall and pulled it out from the engine compartment. There is one small screw inside the case that has to be removed. Took a while to figure that out.
Had this issue for about 15 years. Just had my ac fixed so i decided it was time to do this to get the full AC experience. Thanks for the extra detailed video.
Every issue I've ever ran into with my 91 Chevy Cheyenne 2500 you have had to deal with as well and when I'm lost on what or how to fix it so I highly appreciate you making all the videos u make .... Thank you so much
Thank you for taking the time and extra effort to share your process in replacing this component. Certainly, it helps folks to know what they are up against and promotes DIY confidence . Very helpful, very informative! Brad R, Vancouver, Wa, USA
Thank you for this video. I’ve put this off for about 3 years now because I can’t figure it out and I am scared of getting it out and not being able to put the new one in. I’m also too afraid of taking apart my 26 year old dash because I know I’ll never get it out in one piece. I think I’ll attempt this now. Thanks again Frank
yup, I'm huge with huge hands and I've been listening to that thing for years now. Since the AC is original equipment and doesn't work, I'm now thinking about just snipping those wires from the top. done.. :)
You have been very helpful. Headed to part store, to order my new actuater..... Your down to earth, personalty is refreshing. In a couple of days, I'm going to try my luck.. thank you
Thanks for this, I watched your video and did mine. Instead of the top screw, I shoved a zip tie through the hole and wrapped the other end of it up in the frame around the relays just so it serves as an anchor point.
That screw is the devil !!! I did the same thing cc did and broke it off then i did the same thing you did and put one screw in. Works good now . Thanks for the info .
Dude love the reality of the video extremely helpful and down to earth normal person going through the same pain whoever else is changing out the part that needs the video. Thanks for being real
The actuator near gas pedal controls vent, Defrost, Floor= [MODE ACTUATOR] The center actuator , is the BLEND DOOR actuator that controls hot or cold . THE ACTUATOR by passenger's feet controlS Vent or recirculation ONLY
Thank you so much for this you made my job very easy! I had the same one fail in my truck but it had enough free wire to take out the bottom. I also left the back screw off and mine is working fine.👍🏽
Thanx so much for goin the extra mile and showin us the nitty gritty. Ive got alot of the same issues on my 94 w/t so this playlist is gold! And the look and almost panic people give me when i roll up or turn it off gets sooo old. Im amazed at how few people even know the sound at all smh. I like to come up with crazy explanations for the hell of. Its pretty funny when i go "Oh Shit!!" And holler "RUNNNN!" Just to makem jump. And I 100% dont blame you for lettin the last screw go..hell ive let it thump foe seems like 10 years now, lol..i may omit it myself 😆
After watching the fight you had, I couldn’t even get a socket on the back screw. So I removed the first screw & took a large screwdriver under the actuator lifting up and the actuator popped right off leaving the small piece of plastic under the second screw. I’m not suggesting any one else try this but took 15 seconds for me.
I will probably do the same, two reasons, the old motor is no good anyways so if it breaks, oh well, and the other is having the old motor out of the way may make it easier to see and access that other screw, just my opinion
I wonder if car engineers look at videos at this and snicker at our frustration. Good video, gonna buy one and attempt to get my oven mit hands scraped up this weekend. Thank you!!!
Response: Haha, maybe they do! But trust me, the satisfaction of fixing it yourself outweighs any temporary frustration or scraped knuckles. 💪😄 Remember, patience is key and you're learning something new in the process. Good luck with the actuator replacement this weekend, and feel free to share your experience or any follow-up questions. Thanks for your kind words and for watching!
30 year old truck so I just popped the top bolt. Now I don't have to worry anymore. It's old and brittle. Also replaced to blower motor as it sounded like the brakes were engaged
Pro tip: use a long flat blade screw driver and pry against back of 1/4” ratchet. It keeps enough pressure to back out screw the whole way and keep socket spinning as it gets loose.
This is still easier than a Crown Vic blend door actuator. Thanks for the detailed video, it's greatly appreciated. I'll be using some chewing gum to keep the second bolt in the socket (unless I find something to magnetize it).
Wow that's a tough repair! On my 99 Tahoe I just made sure that the blend door was closed and removed the power plug from the actuator so I'm always on recirculate which is just fine since I live in Florida and never turned the recirculate off to let the outside air in.
another thing to help keep the screw there is that black windshield putty.. good sticky stuff and hold well if you just place a dap in the socket then add the screw in. Great job on the vid! thanks!
7mm screws, not 9/32. I worked 3 friggin hours on that top screw-never did get it til i took my big screw driver and pried it off, breaking it. That 1 bottom screw is all you need anyways because mine now works great!
Thank you so much for the kind words! I'm glad you found the video both informative and entertaining. I always try to add a touch of humor to make the process more enjoyable for everyone watching. 😄
I'm really glad you found the video detailed and helpful! 😊 Best of luck with your 1995 Silverado. Remember, take your time and follow each step carefully. 🚗🔧👍
We have our dash out bc we are replacing it and it was still a pain to get to. We got it out w a very small wrench- me turning from the top and my husband pushing on it from underneath. To get that top screw back in we had to move the computer out of the way. I used my nails to get it in place and turn it just enough to get it started. And then again he held pressure on the wrench from underneath while I turned from the top. I was the one saying just cut the wire the whole time though. Took us about 2 hours from start to finish with a lot of breaks for frustration.
Glad you found my video helpful. I also put up a diagram on my website of all the air door locations www.buildpriceoption.com/air-door-actuator-locations-1988-94-chevy-and-gmc-truck/
You probably all ready got it but it take less then 5min. You need a 8-12in 1/4in with a 9/32 socket 🔧 and 8in long needle nose. So reach up and set the screw push it tight in the hole with your finger tips while your siting out side your door use your left hand to hold the wrench u will feel it sit on the nut test the your set while moveing the wrench side to side up and down to no your seated then slightly pushing it in then with your right hand and finger tips slide it up tords the back and grab the socket the u use your right hand to squeeze while slightly pushing it in then at the same time start with your fingers start wratcheting the wrench it may take a few times to get it started but after that it will go right in just snug it down and your done pretty easy. If u need any more info soot me a message. Hope this helps
Why is it always that actuator that fails? When I did mine I couldn't get to the tough screw. It needs two screws or it gets jacked up when it tries to operate. I'm not proud of how I made it work but after 5 years it still works. I stuffed a tennis ball up in there and it holds the actuator in place fine. A couple of years later I found a tool that would work perfect in that spot. It's called a Tite Reach. They have them in 1/4" and 3/8ths. I bought the 1/4" version with the intention of replacing thst screw but the tennis ball is doing just fine. I have used the Tite Reach several times with several projects.
5.5 mm socket with swivel and cordless ratchet , flashlight and mirror may help. There's just enough room to pull it up through the glovebox to disconnect it! God I love workin on them dusty old trucks!
Man, I have spent HOURS researching this exact same problem on my 1994 Chevy 1500 and your video is by far THE BEST. I am very disappointed you couldn't figure out how to put the last bolt in. Two things, you could have disconnected the wiring harness from the bottom using a long screw driver like I did - real simple. Second, your video is 10 minutes too long because you keep repeating yourself, but my friends tell me I am too wordy too - lol... Otherwise THANK YOU for your time for making this video - It has helped me...Now, wish me luck - lol
I found it impossible - lol to get to that top screw with the tools that I have. From what I understand, this actuator regulates the circulation of inside air vs outside air coming into cabin. I just disconnected the switch and the knocking stopped. I guess I will deal with figuring out a way to loosen the top screw at a future date - lol...Thanks again for your video...
I've done so many of these door actuators on Chevy impalas...that...1. i just buy the plastic replacement gear that strips out and rebuild them myself...2. i install them with one or two screws...never all three screws. one screw will hold them in, but two is best.
I’m going to remove the plenum and replace the heater core, evaporator and all three actuators and be done with it. She has been good to me for almost 500,000 miles.
The screw you are having trouble with Get about a 1 foot long piece of a vacuum line big enough that the screw head will fit in it tightly and start the screw. The vacuum line is flexible enough. Try it it will work an old mechanic trick.
I really like your detailed videos man. I put a whole new ac system in my 94 when I bought it and it blows semi cool air and weak air flow. Also when setting is on the face it still blows from the defrost and fogs up the windshield on the outside. I removed the blower motor and cleaned that out and cleaned the evaporator which was a job in itself especially in Texas heat. Well it did help with the air flow a bit and it seems a lot colder but it still blows from the defroster and fogs up the windshield. I know the 95 and up has the air flow distributor which you have to drop the dash and steering column and I heard it’s a pita to do. I’m not sure if the 94 and under have those. If not maybe it’s the actuator on the driver side floor board. I’m going to spray it with WD-40 and see if it helps, maybe it’s age it’s just not opening all the way. I hope that’s the case.
I am about to do this to my 1993 Suburban. What if....I put a washer that would hold the screw in place, sorta get it started before I slide the blend door motor back into position. Then, just tighten it up? Or is even that to hard to reach? I figure if you can get a tool on to loosen then you can get one on to tighten. Is it just handling the screw that is the problem?
Try a drop of hot glue to hold the screw in place while you position the actuator, it will break loose when you put a wrench on it. Also if you can use a 1/4” air ratchet with a deep socket then it should be a piece of cake. Air ratchet 20.00 harbor freight.
The bottom screw is enough. Done this many many times on various auto's and never had an issue. If it is doable, I do it. If it is like yours, I just leave it out.
My 02c when you are ready to insert the actuator, put all 3 screws in the actuator. Easiest way to explain how to retain them in the actuator is to explain where I got my idea. Look at an electrical wall plug. There are two screws attached to the plug that have a thin piece of plastic on them. They secure the plug to the plug box. I took 3 of those off some old plugs and put the screws through the actuator and secured them with these thin pieces of plastic. When you put the actuator in, and you have all 3 screws lined up. The two the author of this article got to are done first. The hard to reach one has to be literally pinched as hard as possible with the plastic because you do not want to "ratchet back" and have the screw go with the ratchet. So make sure the third screw is really jammed with the plastic. I broke 3 pieces of plastic from electrical plugs before I was able to get one that would hold the screw on the 2-3 clicks you get out of the ratchet. Then, hold your breath and tighten.
great video brother, a little wordy, but you explained it all very well, best one i've found. thanks and keep up the great work. i've got a '94 gmc k1500 and now a '93 chevy 1500 with this problem. i appreciate you making the video, unfortunately for all others out there, i have enough trouble fixing these things, i can't imagine making a video as well, thanks again!
I purchased the part from LMC Truck online. Here's the part number they use, but it's easy enough to search their site by year make and model. (39-2601 AIR DOOR ACTUATOR-AIR INLET)
I just pulled the dash on my 94 to replace the evaporator took me 2hrs i was able to pull the passenger side out enough to get the hvac box out i never want to do this again.
Perfect how to video! No way no how getting to it from top, at least on my 93 Silverado.. I was thinking no need to put the top bolt back in if I can get it out about the time you decided not to so yay! I was able to pull the actuator out the bottom and take wires off fyi.
Great Video - I would have used electric tape to hold the screw in the socket - and A LOT OF PATIENTS TO GET IT IN THE HOLE. - I do have a small camera kit - installed on a flexible tube - it has a light and I could see the alignment of screw to the hole. LAST SCREW IS VERY TOUGH !!
Thanks for making this video - helped me to get my truck fixed. The actuator failed and the mode door defaults to hot air only when it fails. I made a tool to get the door aligned with the new actuator. I used square stock (a broken 1/16 inch pin punch) that fit in hole in the actuator and into the slot on the door. I then used a tiny adjustable Swedish nut lathe (crescent wrench) to line things up. The square stock has to be cut 2 1/4 inches. Any longer and you can't get back out and shorter is, well too short to work. I took out the vents and the tape player as there was no way my sausage fingers were getting any where near the inboard bolt. My truck is an 1988 and the actuator was the original.
Hi there! Thanks for taking the time to watch my video on the Air Door Actuator Replacement for a 1994 Chevy Cheyenne C1500. I'm glad you found it helpful and appreciate your kind words. Happy wrenching!
Good video! I'm going to try taping the screw to the actuator or using dum-dum to hold it to the actuator while installing it. I'll let you know how it goes.
couldn't get the last screw either. So now I got a rope attached to the flap door that runs up to a pully the attaches to a choke switch on the glove box, now when my girl wants that cool recirculating AC she can just pull on that rope.
You are suppose to remove the Computer and computer holding bracket allowing you to get to the the top 9/32 screws to remove it. Then you'll have plenty of room to remove screws and wiring connector.
I need to do this for my truck. I wonder if you can swap the original metal socket-like piece with the new actuator's plastic one? As for the back screw, I've also used a tiny drop of crazy glue on the screw head to keep it from falling off. Just a tiny amount is all you need. Thanks for the video!
A good way to get the screw in is to take a small piece of aluminum can and secure to the screw's threads holding screw in place on the actuator. Even a small amount of medium grade silicone sealant would work. Whatever you use keep in mind it might have to be changed out again one day so don't use a strong sealant like Masterseal NP1.
That's a good question. My truck has a digital climate control system but I believe these trucks are manual climate control systems. Automatic Climate Control is a feature that automatically adjusts your vehicle's climate system to heat or cool it to the temperature you specify. I know my truck doesn't do that in any way.
For the unit(Actuator)your working on, if you move the computer from it's bracket you'll have more room to work in, then again I have small hands. Good luck, it can be a pain in the rear door.. :) Lol

I just asked about that before reading the comments. Glad to see it works. This will be my plan for a first attempt.
I do a dab of dielectric on the shoulder of the bolt head myself

Thanks, just bought my first truck a 1994 GMC Sierra SL 2500. Got the same problem, previous owner didn't know what the noise was either.
All three have an alignment pin and two screws. That is what I found on my 96+ OBS trucks. BTW, great video.
30 year old truck so I just popped the top bolt. Now I don't have to worry anymore. It's old and brittle.
Also replaced to blower motor as it sounded like the brakes were engaged

That's awesome! Nine months is a long time to hear that clicking. I think I went a week or two. Thanks for watching and glad my video helped you out.
Wow that's a tough repair! On my 99 Tahoe I just made sure that the blend door was closed and removed the power plug from the actuator so I'm always on recirculate which is just fine since I live in Florida and never turned the recirculate off to let the outside air in.
Did the same my 1500 10 years ago and I didn't put the top screw in. Never had a problem.
Thanks brother, I'm about to replace this actuator and the fan motor at the same time. I'm feeling pretty confident now after a few videos 😎
You're very welcome my friend. I hope the job goes smoothly for you.
Thank you for this. Mine was draining my battery cause it stayed on after the truck was turned on. Thank you so dang much..
You are very welcome. And thank you for watching.
Came here for the flap tip. I couldn't get it line up. Thanks!
Great video. One of the most helpful I’ve seen for this truck. Thanks
Thank you so much for your kind words! I'm really glad to hear that you found the video helpful.

Use longer screw with washers where screw sticks out enough to get socket on it
We have our dash out bc we are replacing it and it was still a pain to get to. We got it out w a very small wrench- me turning from the top and my husband pushing on it from underneath. To get that top screw back in we had to move the computer out of the way. I used my nails to get it in place and turn it just enough to get it started.

Mannnnnn thank you. My truck just doing this. I appreciate you brother
A part number would be great. Great video only one who actually helped!
94 MODEL CHEVY GLOVE BOX CAME WITH ROLLING TRAY AND 2 BEER HOLDERS
Good job explaining this. Very detailed. Thanks
Thank you. I'm glad it was helpful.
this is uncle dig try securing screw in start position with silicone prior to replacing actuator good luck video very helpful
Glad you found my video helpful. I also put up a diagram on my website of all the air door locations www.buildpriceoption.com/air-door-actuator-locations-1988-94-chevy-and-gmc-truck/
You probably all ready got it but it take less then 5min. You need a 8-12in 1/4in with a 9/32 socket 🔧 and 8in long needle nose.
So reach up and set the screw push it tight in the hole with your finger tips while your siting out side your door use your left hand to hold the wrench u will feel it sit on the nut test the your set while moveing the wrench side to side up and down to no your seated then slightly pushing it in then with your right hand and finger tips slide it up tords the back and grab the socket the u use your right hand to squeeze while slightly pushing it in then at the same time start with your fingers start wratcheting the wrench it may take a few times to get it started but after that it will go right in just snug it down and your done pretty easy. If u need any more info soot me a message. Hope this helps
Why is it always that actuator that fails? When I did mine I couldn't get to the tough screw. It needs two screws or it gets jacked up when it tries to operate. I'm not proud of how I made it work but after 5 years it still works. I stuffed a tennis ball up in there and it holds the actuator in place fine.
A couple of years later I found a tool that would work perfect in that spot. It's called a Tite Reach. They have them in 1/4" and 3/8ths. I bought the 1/4" version with the intention of replacing thst screw but the tennis ball is doing just fine. I have used the Tite Reach several times with several projects.
Well luckily this hasn't happened to me but I'll keep this in mind if it ever does thanks for the video!
Thank you for watching. I wasn't looking forward to this repair, but now I have the experience under my belt.
5.5 mm socket with swivel and cordless ratchet , flashlight and mirror may help. There's just enough room to pull it up through the glovebox to disconnect it!
God I love workin on them dusty old trucks!
Thanks for the tips!
Man, I have spent HOURS researching this exact same problem on my 1994 Chevy 1500 and your video is by far THE BEST. I am very disappointed you couldn't figure out how to put the last bolt in. Two things, you could have disconnected the wiring harness from the bottom using a long screw driver like I did - real simple. Second, your video is 10 minutes too long because you keep repeating yourself, but my friends tell me I am too wordy too - lol... Otherwise THANK YOU for your time for making this video - It has helped me...Now, wish me luck - lol
I found it impossible - lol to get to that top screw with the tools that I have. From what I understand, this actuator regulates the circulation of inside air vs outside air coming into cabin. I just disconnected the switch and the knocking stopped. I guess I will deal with figuring out a way to loosen the top screw at a future date - lol...Thanks again for your video...
@@ricoescobar4986 I hope you got it figured out!
I will have to do this before it gets cold. this video helps.
I've done so many of these door actuators on Chevy impalas...that...1. i just buy the plastic replacement gear that strips out and rebuild them myself...2. i install them with one or two screws...never all three screws. one screw will hold them in, but two is best.
Thats awesome to know!
I got tired of the ticking so i just unplugged mine 😅
I’m going to remove the plenum and replace the heater core, evaporator and all three actuators and be done with it. She has been good to me for almost 500,000 miles.
The screw you are having trouble with
Get about a 1 foot long piece of a vacuum line big enough that the screw head will fit in it tightly and start the screw. The vacuum line is flexible enough. Try it it will work an old mechanic trick.
Thanks!! I just did it with hose and went right in!! Job done!

I'm glad that you found the tip helpful. Thanks David
Exactly what I did!
Thank you. I just replaced mine thanks to this video.
I really like your detailed videos man. I put a whole new ac system in my 94 when I bought it and it blows semi cool air and weak air flow. Also when setting is on the face it still blows from the defrost and fogs up the windshield on the outside. I removed the blower motor and cleaned that out and cleaned the evaporator which was a job in itself especially in Texas heat. Well it did help with the air flow a bit and it seems a lot colder but it still blows from the defroster and fogs up the windshield. I know the 95 and up has the air flow distributor which you have to drop the dash and steering column and I heard it’s a pita to do. I’m not sure if the 94 and under have those. If not maybe it’s the actuator on the driver side floor board. I’m going to spray it with WD-40 and see if it helps, maybe it’s age it’s just not opening all the way. I hope that’s the case.
😊
You are right brother.. pain in the ass I'm doing mine right now 😂👍
I hope it went well!
I used the tire iron that is under the back seat and pried it out after removing The front bolt. It was then easy to remove the upper bolt.
I am about to do this to my 1993 Suburban. What if....I put a washer that would hold the screw in place, sorta get it started before I slide the blend door motor back into position. Then, just tighten it up? Or is even that to hard to reach? I figure if you can get a tool on to loosen then you can get one on to tighten. Is it just handling the screw that is the problem?
Try a drop of hot glue to hold the screw in place while you position the actuator, it will break loose when you put a wrench on it. Also if you can use a 1/4” air ratchet with a deep socket then it should be a piece of cake. Air ratchet 20.00 harbor freight.
The bottom screw is enough. Done this many many times on various auto's and never had an issue. If it is doable, I do it. If it is like yours, I just leave it out.
Well sonofabirch. Just did my blower motor and heater core, thought the clicking was the blower motor. Time to pull the dash apart again.
My 02c when you are ready to insert the actuator, put all 3 screws in the actuator. Easiest way to explain how to retain them in the actuator is to explain where I got my idea. Look at an electrical wall plug. There are two screws attached to the plug that have a thin piece of plastic on them. They secure the plug to the plug box. I took 3 of those off some old plugs and put the screws through the actuator and secured them with these thin pieces of plastic. When you put the actuator in, and you have all 3 screws lined up. The two the author of this article got to are done first. The hard to reach one has to be literally pinched as hard as possible with the plastic because you do not want to "ratchet back" and have the screw go with the ratchet. So make sure the third screw is really jammed with the plastic. I broke 3 pieces of plastic from electrical plugs before I was able to get one that would hold the screw on the 2-3 clicks you get out of the ratchet. Then, hold your breath and tighten.
Truck looks good I've got a 91 z71 5.7 5 speed I done frame up rockers can corners and paint my self
i just unplugged the bad one and said the hell with it. no more noise.
great video brother, a little wordy, but you explained it all very well, best one i've found. thanks and keep up the great work. i've got a '94 gmc k1500 and now a '93 chevy 1500 with this problem. i appreciate you making the video, unfortunately for all others out there, i have enough trouble fixing these things, i can't imagine making a video as well, thanks again!
btw, where did you get the part? part #?
Much appreciated!
I purchased the part from LMC Truck online. Here's the part number they use, but it's easy enough to search their site by year make and model. (39-2601
AIR DOOR ACTUATOR-AIR INLET)
I got mite in with one of those 90 degrees screw drivers.
Pain in the bit but it worked
I just pulled the dash on my 94 to replace the evaporator took me 2hrs i was able to pull the passenger side out enough to get the hvac box out i never want to do this again.
Perfect how to video! No way no how getting to it from top, at least on my 93 Silverado.. I was thinking no need to put the top bolt back in if I can get it out about the time you decided not to so yay! I was able to pull the actuator out the bottom and take wires off fyi.
Right on and glad it helped! Thank you for watching.
The water pump, I would've done myself. This is the project you send to the shop.
Great Video - I would have used electric tape to hold the screw in the socket - and A LOT OF PATIENTS TO GET IT IN THE HOLE. - I do have a small camera kit - installed on a flexible tube - it has a light and I could see the alignment of screw to the hole. LAST SCREW IS VERY TOUGH !!
Thanks for the video it was very helpful
Glad it was helpful and thanks for watching
Thanks for making this video - helped me to get my truck fixed. The actuator failed and the mode door defaults to hot air only when it fails. I made a tool to get the door aligned with the new actuator. I used square stock (a broken 1/16 inch pin punch) that fit in hole in the actuator and into the slot on the door. I then used a tiny adjustable Swedish nut lathe (crescent wrench) to line things up. The square stock has to be cut 2 1/4 inches. Any longer and you can't get back out and shorter is, well too short to work. I took out the vents and the tape player as there was no way my sausage fingers were getting any where near the inboard bolt. My truck is an 1988 and the actuator was the original.
good job men
Hi there! Thanks for taking the time to watch my video on the Air Door Actuator Replacement for a 1994 Chevy Cheyenne C1500. I'm glad you found it helpful and appreciate your kind words. Happy wrenching!
Hi I have a 93 c1500 my climate control flashing arrows do I think it’s the actuator I’m not getting heat
I've super glued the screw into the socket to hold it from falling out.
Good video! I'm going to try taping the screw to the actuator or using dum-dum to hold it to the actuator while installing it. I'll let you know how it goes.
Exactly the problem I have. Thanks.
Appreciate this Brother!
You're very welcome! I'm glad you found the video helpful. Happy wrenching, and thanks for watching! 👍🔧🚗
Hi sir@@BuildYourOwn
Hell yes thank you brother😎🇺🇸👍
Glove box gives u so much room man
couldn't get the last screw either. So now I got a rope attached to the flap door that runs up to a pully the attaches to a choke switch on the glove box, now when my girl wants that cool recirculating AC she can just pull on that rope.
You are suppose to remove the Computer and computer holding bracket allowing you to get to the the top 9/32 screws to remove it. Then you'll have plenty of room to remove screws and wiring connector.
That's a top tip! Thank you.
Is that right? I’m about to put my 94 tall joe under the knife and am stocking my info arsenal to increase my success. Thanks
I need to do this for my truck. I wonder if you can swap the original metal socket-like piece with the new actuator's plastic one? As for the back screw, I've also used a tiny drop of crazy glue on the screw head to keep it from falling off. Just a tiny amount is all you need. Thanks for the video!
Great video.
beautiful truck
Thank you!
A good way to get the screw in is to take a small piece of aluminum can and secure to the screw's threads holding screw in place on the actuator. Even a small amount of medium grade silicone sealant would work. Whatever you use keep in mind it might have to be changed out again one day so don't use a strong sealant like Masterseal NP1.
Hi does these truck have manual or automatic climate control
That's a good question. My truck has a digital climate control system but I believe these trucks are manual climate control systems. Automatic Climate Control is a feature that automatically adjusts your vehicle's climate system to heat or cool it to the temperature you specify. I know my truck doesn't do that in any way.
Thanks for the detail. I think I feel like I can maybe do it. Great video.
For the unit(Actuator)your working on, if you move the computer from it's bracket you'll have more room to work in, then again I have small hands. Good luck, it can be a pain in the rear door.. :) Lol
Thanks for the tips!
Just unplug the actuator,, and leave the door close to outside mode,,, And use inn cab air,, it gets cooler on a/c mode,,,
