Scotty Kilmer what year is this vehicle and which years would you consider having that same type of resistor
Scotty Kilmer I replaced the blower motor resistor on my 94 Toyota 22RE and it’s still blowing weak. I replaced because it used to stopped blowing after 20 mins of driving and blowing weak, but it’s still blowing weak.
My car blows heat, but it doesn't get really hot, just feels warm...what's the problem?
Thank you Scotty, who needs to pay a mechanic when we have you teaching us. I changed my "in-line fuel filter thanks to you. You have taught me many things. Thanks dad.
Scotty should receive 5 bucks every time somebody fixes something in their own car with his videos. Let’s make Scotty a multi millionaire.
Scotty to the rescue! Moreover he shows us all his magic. Thanks Scotty for helping folks help themselves 😀
This was a really well done video Scotty!
Thank you Scotty! Fixed my ac thanks to your video! Can't believe the dealership wants me to leave my car with them for 5 days with no guarantee. Saved me time and money!
my number 1 teacher. thank you Scotty
Mr. kilmer i don't really have a question i just want to say thank you for making your videos and i hope you keep making many more. there really helpful 👍
This man is such a Legend !! Thanks Scotty you are my mechanic pop !!
Great Vid Scotty, have had this problem on so many cars! easy fix though :)
love your shows
Thank you Scottie, God Bless
love ur stuff scotty!!!!
thank you scotty! your videos are helping me fix my old saturn
This happened in my 04 Acura MDX. They wanted $230 for the part, so I took the module apart and replaced the transistor for $8.
Dealers rip people off all the time.
Hey Scotty, my car blows air very nicely on the highest setting except when I switch it to face and feet, on that setting even with the fastest blower setting hardly any air comes out, any thoughts on what to look for?
Hey Scotty!! Love your channel! I have an 02 Grand Prix and my vents are not blowing very hard at all. I’ve already replaced the resistor which didn’t help at all. Would the blower motor be the problem? Thanks!
Thank you for the video. My hyundai Santafe's ac (cool/heat) works fine. I have recently noticed that sometimes I can hear the fan responding to the fan speed knob normally but the air from vents is so weak and I hear like the air is being leaked somewhere inside above the glove box. My cabin filter is new and it makes no difference if I run the fan without a filter too. Can you please advice what could be the issue ?
great vid Scotty!
I had two problems in the blower assemblies (yes, I got 2) in my car. Each blower assembly has 2 relays, I replaced all 4, then the right side blower stopped working due to the worn out motor brush. I bought slightly bigger brushes, filed them down to the correct size and both blowers work flawlessly ever since. I had a 3rd problem that stopped the blowers working and it was a cracked solder joint in the fuse box. I resoldered all the cracked joints in both fuse panels. Overall the 4 relays cost the most of the whole repair job.
Awesome video! Thanks alot.
great info....
I've always wondered about this. My Envoy XL has a problem where the fan totally turns off on the highest setting, and I knew it had to have something to do with the circuitry that controls the current going to the fan. Thanks Scotty!
megakiller999 common problem on the envoy
Nice work 👍🏻
Thanks for the tip Scotty.
Happened to my old car. Mechanic too busy to fix it so he just showed me where the resistor was and said, "Just replace that". I did.
wholeNwon Saved u a couple hundred. Nice guy
More like just the price of the part. He was a great mechanic...really superb and very honest. Had the most loyal following you can imagine. Have a million dollar plus 12 cylinder Ferrari that no one could tune just right? He was your man. Mercedes 600 that even the dealer's techs had never seen? He was factory-certified! That sort of man. You should have seen his little office at xmas time...filled with gifts even though he would specifically ask people not to bring them.
He didn't take just anyone for a customer. He gave preference to people who needed their cars for work not when they were just parts of large collections, though he had a fair number of those, they had to wait for repairs.
Great vid! My car AC temp starts at 64 and the high is 90
scottys the man. a mechanic you trust..
Hey Scotty great show. Do blower motors wear out over time. My system is clear of obstruction....but just not a lot of air coming through the vents. Seems like it is running on medium.
Thank you. U helped me fix my ac. It works now😀😀😀😀
Glad to hear it thanks for watching!
didnt even know they had one lol. ur knowledge goes far and beyond.
you always got all the right info!! can you show how to fix a ac that isnt blowing on the face vents i dont trust other videos!! but as always thanks for your channel saves me alot of money and i look like a bad ass when it comes to fixing minor problems lol
Blend door or actuator or computer problem. Analyzer can determine whether a signal from the computer is being sent to the actuator and whether the actuator is responding and therefore where in the system the problem lies. Common issue. All this assumes you have a "modern" vehicle.
Thanks Scotty!
The Asylum looks like a really nice and chill place for a couple of beers.
Very helpful! Have the exact problem on my 1994 7.3 powerstroke!
Excellent video!
Nice! So much easier on that car than my former Lincoln Mark VIII's and mid 90's Thunderbird!!
Hello Scotty,
I have a 2016 Nissan Altima SR and recently had a new compressor put on (crazy to believe the vehicle only had 63K miles), all in all they could not figure out what was wrong with the old compressor and replaced which got me cooling. But aside from that my question is now (just like in this video) the air doesn't blow strong. But what is more interesting is that it starts off at a good pressure, but then I'd say after the vehicle has been cooling for about 15-20 mins (sometimes longer) the pressure gets low and weak to where I don't feel it. Most times if I crank it up to full blast I can hear it, and then it finally pushes through, but I don't want it on full blast all the time. Would what I'm describing be the blower motor resistor, like in this video? Any feedback would be greatly appreciated. Thanks!
Scotty, I have heat strongly out of the side vents but low out of the center vents, what could it be. 2008 acura tl type s. Thanks
good work scooty
you are a good man!!
Hey Scotty, I have a customer that brought me a 1999 GMC Safari 4.3l with an issue with the HVAC system not blowing air through the vents (only blows through the floor and defrost). I have found and fixed the vacuum lines that were damaged, I've replaced the blend door actuator as well as the HVAC control panel but still has the same problem. What am I overlooking here?
Scotty . . . you the man
I just fixed my 2000 jetta which did not blow at all because the resistor and main control panel under the radio were busted now with the ax and heat blowing the heat doesn't tend to get very warm even after it's been sitting for a while running is this a heater core problem and is there an easy way to do that without removing the whole dash
Hi Scott we replaced our a/c piping and rad in the back and a little pin hole in the front aluminium a/c hose on our 2010 grand caravan. It worked fine for a couple of seasons but now on occasion you can hear like air or a really loud harley going through the pipes from the front to back for a couple of seconds then stops once it reaches the rear. But recently its been getting worse. Do you have an idea what this could be?
Thanks
I would change the receiver drier to catch any foreign bodies inside the system from stuff like degraded rubber hoses inside
Any input for the 07 tundra and this issue? Can’t seem to find a blower motor resistor but these symptoms are the same as mine?
Really good video. The blower, or the blower regulator failed in my Mercedes yesterday. It would only blow air for a few seconds and stop, or not blow any air at all... Mercedes wanted 500 Euros to change it, I politely refused and decided to change the thing myself. Gonna buy the parts from the warehouse that supplies Mercedes with parts and swap it out next week.
Thank you
I have a 2006 toyota Corolla that has the same issue, is it as easy to fix as this car in your vid? And if so, how much does that part cost?
you are awesome scotty i like your videos
Scotty, my ac blows pretty well 3 of the 4 vents. But 1 one of the vents, the one that is the left of the steering wheel, blows very weak. What do you think may be causing this.?
Hey Scotty, how do you repair blend door actuators on 1996 Town & Country minivan?
I have the same problem on my 2008 Chevy Silverado is the blow motor resistor in my truck located in the same area?
I asked this question on during Cartalk on Saturday but didn't get answered. Thanks for doing a video on it.
Hi Scotty, I have a 2012 Chevy Traverse and my ac isn't working good at all. It won't turn on unless I turn the knob to the highest setting. When I do it blows like it's on the 1st setting. So it turns on on 4 and blows like 1. It is cool air that is blowing, just very weak air. I changed the resistor and that didn't do anything. You have any thoughts on what it might be?
Surprised to see something like that go out on a newer infiniti, ive had my 09 g37 for many years and its never had any issues like that. Looks like parts are being made cheaper and cheaper.
yep, they sure are
Dark Bounty there is also bound to be a certain number that leave the manufacturer that test good bur have a wonky circuit in there.... the same with all newer electronics... Millions of good ones and 1-3 bad ones...
'09 is nowhere near old. In fact, 09 is a really shit period for cars. It was the height of shitty manufacturing to start with. 09 is not old enough to be cool; you look cheap. Plus, all warranties are now expired, so your car will soon self-destruct.
Dark Bounty Dude Nissan alternators are shitty alternators and compressors are shitty based on my experience. Me and my dads cars have had to change both. Mines old but my dads car is new.
Hi Scotty, you are awesome. I got question for you. I got Toyota Prius V 2014. The heat mode to my legs didn't blow up, but forehead and the dashboard are working fine. Would please tell me how I can fix it. Thank you so much!!
those are insanely complex computer run heating systems, find a guy with a toyota dealer scanner to analyze it. often a bad blend door actuator, but they are expensive and very hard to replace
Scotty Kilmer For President!!
Hey Scotty, car was running greaet but today
i installed push button start system in my ford escort zx2 178k MTX, turn it on with the button, then i turned it off and the on then off then on then off, at the 5th time that i dis this consecutively, smoke came out under the hood on the passenger side.
then the rpm's went low and then the car died, since i started it on and off and on and off , would there be a chance that the smoke was caused by the timing belt jumping or something for starting in and shutting it off consecutively so quickly? or not.
car now starts , rpms go as normal, then they slow down and then the car dies, unless i give it gas. as long as i give it gas the car will stay on but as soon as i let go , rpms go down and it dies.
if no the timing, then what could it be ? car was running great before that.
Real mystery, looks bad
Scotty should you check the blower motor bearing once in a while and change them if you can and also spray something that will kill the fungus inside as a preventive measure? Or just clean them with alcohol?
Hi scotty.. i have a weird issue.. my fan blower controller is working i beleved but in the most highest i still no feel that same power of air flowing from the vents. I change the fan blower and with the new i put have the same issue.the new i put is used but from a car was be totalled in a crash and i onspected and looks pretty new. But have the same issue of the old one and have the same power when i change in the controller fan console in all stating in low and high.. did you beleved is the resostor?
Have you sorted it out? I have the same issue.
Hi Scotty I had that sort of problem but I just changed the blower motor. Is there a chance my blower would stop if my resistor is the problem ?
when fill out the AC, it leaks immediately under the car and it leaks a lot. Any stop leak you recommend ?
Hey scotty my ac in max barely blows air I can feel it more in the higher setting but barely and the lowest barely even air coming out but I can hear the blower motor on full speed it gets louder when I put it on max but the air coming out should be way more then that maybe the cabin filter is clogged ?
Hey Scotty I have a 2005 Buick park avenue my blower motor work but lately I’ve been taping on the dash and it work for awhile then kicks off again
hi scotty.. I have a 05 silverado 5.3l v8. the new blower motor risister has a different connection than my truck. the truck only has 3 wires on the plug is a box and the new ones have a long 8 wire plug that don't fit. any ideas?
Thanks scotty
I have a 2011 ford f350 and blows but not hard I ju st installed a blower motor any thoughts
I replace all those in the front and back parts in my 2007 Chrysler Pacifica 4.0 Edition! But in the front it blow hard but in the rear it isnt! Any hints on how I can fix or improve that issue!
i have same issue but if i put the mode to the window its working normal but if i change it to face or foot i have same problem you mentioned.
I just did this for my Durango. I also had to replace the motor since it kept blowing the resistor. Old one didn't spin freely like the one you had in your had.
ty
Scotty I just want to know if I need new tires before doing a wheel alignment? I know I need a wheel alignment but just need to know what to do before getting one done thanks!
get new tires first, then have aligment checked, you can't align a car with bad tires on it
Scotty I have watched different videos over the last couple years.
I have a car that the ac and heat works. The blower is blowing like it should. Here’s the catch, if I start the car and drive short trips it blows through the vents just fine. If I go further than an hour or so then the air coming through the vents slows down to a trickle. Could this be the resister? Thanks again.
Any response to this? Same issue here.
I have a 2015 Passat tsi, the ac isn’t blowing nearly cold or crisp. I took the cabin filter out to replace it and it started to blow a little faster not a lot but still not as cold as I feel like it should be. Should I check this piece out? Also I noticed it happened about a month or two ago when the passenger side blew cold air and driver side was fairly neutral... please help!
Scotty! I have a 2012 Chevy Cruze that has a problem when you leave from a stop the driver info center says service stabilitrack the parking brake light comes on and so does the ABS; then it all goes away. It doesn't do this all the time. Had the code read at autozone and it came up as a C0800 code.
Would you be able to tell me where is the blower motor resistor located on a 2013 Dodge Avenger. I bought a part that said it was a blower motor resistor kit but I replaced it and my air still isn’t blowing like it should but then I came on here and watched ur video and I see the part u just replaced. It’s one that says it fits my car on amazon but just in case i would like to know where it’s located
Could you show it on your Celica Mr K? I have a ST205 GT4 so i'm presuming they would be similar to your 202 :)
Would this work for 2012 Dodge Grand Caravan?
Hey i have a question. The blower motor on my 2015 Toyota Camry seems to be losing power and making a noise. That give there's something in there I don't know but that wouldn't cause it to lose power. And I have no idea what to do. What should I do
Hey Scotty what year and model is that Infiniti?
Hey scotty, im thinking about replacing the fog lights on my tacoma with some LED light pods. Will i have to hook any new wiring components up before the pods?
I don't think so, LED uses less power, so no you won't need new wiring, everything you need comes with the kit
French Canadian Bastard It just came with pods and mounts nothing eletrical
TopDawg e That's everything you need
What if the fan is changing speeds but still doesnt seem strong enough. Would that still be a transistor or is there a way to upgrade it?
Scott my blower works on my suburban but no cold air. expensive fix?
I have a 2005 Ford Explorer. Doesn’t seem to have a cabin filter. My blower is working. Kinda. High (4) seems fine. Going down to 3,2 and 1 it’s basically no air at all. It is blowing but faintly. Also, I can feel the air speed change one 1,2 and 3 but barely any difference. Any advice? Thanks for sharing. 👍🏼
Scotty, I have a 1979 ford f350. My blower motor resistor is shot, and no replacements are available. Can I repair my resistor, or retrofit the the resistor from a ford van (very similar)?
retrofit
hey scotty, my ac blows in exhaust smell even though i installed a new carbon cabin filter! what do you suggest me to do?
Slengo Slengaw find your exhaust leak
My i20 2011 asta AC blower works on high speed. Speed control display showing speed is changing but blower speed is not changing. I have replaced resistor but still issue exist. Will you please help? Is there any issue with fuse or relay?
what if its switches fine on the switch and on the speed of air coming out but what is wrong with mine when am driving and have the ac on high it throws air hard then alil bit slower then goes back to hard and continuously does that. can it be the blower? today am changing the compressor and clutch and the expansion valve and dryer cuz it's not cooling properly. just and fyi
I’m having this same issue on my jimmy but it doesn’t always do it.... it will run fine then out of nowhere it will blow really weak for a minute & then blow normal again... is this the same issue?
I have this same issue, except the blower motor works fine, thus the airflow is still weak. I assume there's a blockage in the system somewhere, but I lack the know-how and the tools to diagnose where the blockage in airflow is. I first tried replacing the cabin air filter. I also tried one of those evap core cleaners that you shove up the drain hose, but it didnt seem to improve much. any tips?
check the intake area for kleenexes or blockage. If not that, often just a worn out blower motor not spinning fast enough
i just had some corrosion on the contact points of my blower, sand paper fixed it! (W208 CLK 1997)
I kinda recently did this on my mom's Jeep Liberty, 2 kinda bad placed bolts but no big deal, the swearing part was that little dang connector, you know, the Chrysler ones that you gotta get a little pick to undo them, I was so mad I threw a pair of needle nose pliers on the floor and they punctured the thick rubber carpet. But most of the time I talk to myself: what would scotty do in this situation, he doesn't swear (on video) he's always so nice and calm, and this actually gets me to cool down
scotty will frequently turning on and off the air con lead it to failure? i drive a 2010 and have had no issues ever, but just thinking
Na, most modern systems can handle that fine, as in many auto climate control systems they run the a/c nearly all the time except when it's below freezing temps.
On my mums Ssangyong Rodius when the car is heating there isn't as much airflow, the blower is going at the same speed but it isn't as powerful as when the car is cooling. Is this just the airflow resistance of the heater matrix? It has quite a large difference between the two.
cabin filter is intact so i doubt there is leaves on it :P
I have an 04 Pacifica blows air through the windshield vent but barely blows any air on the front vents at full speed any idea ?
bad actuator in the dash is common
I have a problem with my heating/AC it will make clicking noises and now will blow at full speed for any adjusted speeds. Is it the switch as well??
Hey Scotty! I have a 99 BMW 323is with a similar problem. When I increase the fan speed it goes faster, but when it's on full blast the air that comes out of the vent is still weak. Is this the same problem?
Thanks!
Did you sort it out? I have the same issue.
I have a 2020 corolla le. I just noticed that when i turn up the heat to the max and just turn it off. The fan stops blowing air but heat still comes from the vents when I’m driving but when I set the temperature to low and turn off the system the heat stops coming from the vents. Is this normal?
Hey scotty, we did the same thing to my dads 88 oldsmobile delta 88 and it doesn't blow any harder it just makes a loud noise with hardly anything coming out. Thanks
Have a 1990 Oldsmobile 88. My car has a problem with it not blowing at a fast top speed. It ranges in speed, has like 10 of them, but full blast is just... weak.
Often a bad blower motor or air is leaking out somewhere in the hvac case (check the blower motor's mounting screws to see if they're tight).
