- Walk-through of how to diagnose and perform service bulletin for A/C servo motor replacement. Guest stated that her center passenger vent was blowing hot when it was set to MAX COOL setting. I verified the concern and fixed the issue, and the customer was happy they didn't have to pay a penny since they vehicle fell under the service bulletin. This is a common Lexus problem. Check in with your local dealer as soon as you experience HVAC (heating ventilation, air conditioning) concerns to see if you are covered under the service bulletin or extended campaign. You may be eligible for a free repair. Thanks for watching.
Wow this was the best details Video on UTube
Thanks for watching!
Do you are awesome, mine just went out today. Your video was perfect., very detailed and well executed
Thank you!
It’s about time you release something from the archives!😁
Serio. 😅
Thank you for this video I have a is2008 haven’t had any AC issues yet but this is good to know of this problem
Thanks for watching. I don't think the 2008 model IS350 or IS250 have this campaign. It's on the 2013 and up. But if the servo motor does go out this is a similar process for replacement!
So definitely call the dealership before attempting to repair this yourself. I just called this morning and explained my issue and they said this is covered up to 125000 miles. I have a 2017 is350 f sport with 58000 miles. I'm taking it in tomorrow for repair.
Yes, that's the first direction to go! The customer support program covers vehicles 7 years from first use or 125k miles, whatever comes first. So you should be good
@@harborareatech310Im having the same issue on my 2016 IS 300 AWD 66k miles
I received the same recall coverage
Will they replace the compressor?
Great video, able to show replacement vid for B1453 and B1455, having driver's side blowing hot air issue and no warranty given by dealer.
When the opportunity arises I will. The concept is the same just on the opposite side. Those are easier to replace as well
Did you ever upload the video for the other side?
@@erickespinoza6998I’m having this same problem with my is350 right now I scanned it and it says driver foot servo motor circuit did u ever figure out how?
Can you please make a video on how to change the air outlet damper cool contorl servo motor? My ac is blowing hot air. It’s from the passenger side it’s so high up I can’t reach it
@@KoolieBhaidid you get a check engine light?
Because my 16’ IS 300 with 66k miles is blowing hot air
But no check engine light
Very helpful! Thanks very much!
Thanks for watching!
Just dropped off my 2017 IS 350 for the exact same issue. I got a letter from Lexus indicating my warranty for the AC was extended 7 more years or 125k miles
Thats whats up!!
@@harborareatech310 The Lexus El Cajon dealership had 2 LFAs in their show room. One being a Nurburgring Ring edition ONLY one in red over 2 million dollar car (the only red 3P0 LFA) 🔥 the other one being a red LFA. So BEAUTIFUL….!!!
@HAULUUZ If im ever in that area, i will have to make a stop for that!
How long did it take to replace it? need to get mine replaced 16 IS 300 66k miles
I have a rc 2019 my servo #1 87106-30510 is going bad Lexus quoted me 3k+ to replace it. I’ve bought the servo that’s going bad and I want to replace myself but if I disconnect the battery is anything else going to deprogram? Also if I replace the servos myself is it mandatory that they need reprogramming?
@josephribs if you disconnect the battery and/or replace a servo motor(s), they would need to be initialized for optimum performance. If not, they most likely would work but not at its best performance. Ch3ck out my video ruclips.net/video/Ad2X1XXt3Sc/видео.htmlsi=-8IJsXdISHzg2Yxp This is an affordable scan tool I recommend al toyota and lexus owners to have. It is capable of performing the servo motor initialization and many more functions.
@@harborareatech310thank you I appreciate it!
So there is a much easier way. Loosen the 2 little silver screws all the way, that are on the outside of servo that you can see.
This releases the servo from the mounting bracket. Then remove mounting bracket from new servo and install back on Car on old mounting bracket.
Once you break the screws free which is very easy, you can remove and reinstall with your finger tips then snug up with Phillips. Sooooo much easier!
Note slide the long mounting bracket screws back in the servo before insta😅lling servo on car.
@bliffblam interesting, never done it that way
@harborareatech310 dude, I fought forever with that back screw. Then I looked at the new servo and said "wait a minute" lol I can just take the mount screws out.
You have to lay on your back to get the bottom one next to heat pipe. Took me 5 min to get servo out and new one in if that.
They're machine screws. So like I said. Once you crack loose you can spin out with your fingers, hands must be dry and not slippery. Put them back the same way.
Try it out next time.
what year u doing is350 ?? mine 2017 RC200t F sport have this problems too will get techstream and start order new servo motor working on it soon
I think this was a 2017 is200t but it's affecting a number of lexus vehicles
Great video! I just noticed my RC350 was doing this about two months ago. Seems like a project I can handle.
Question: I have that nasty smell when I first turn on my A/C. I can't do the evaporator cleaning where you spray cleaning foam using the drain line due to it being on top of the transmission. Would I be able to do that cleaning when I replace the servo? Is there a spot I can insert the spray or would I have to drill a small hole then plug it after?
Thanks!!
Thanks! Always check with the dealer first to see if you're covered. If not, refer to the trouble code to see which servo motor is at fault.
On your vehicle, it shouldn't be that hard to replace them.
To answer your question, I dont remember off the top of my head, but you may have an access view of the evaporator through the inside of the vehicle toward the firewall center area on the passenger or driver side. If so, you can spray the evaporator through there. if not, you can always spray the outside cowl area with the a/c on max with the fresh air mode on and all windows closed. Then, always replace your ac filter with the charcoal style one, and when turning off your vehicle, ALWAYS leave your ac on fresh air mode to prevent excessive moisture buildup. That is what causes that mildew odor.
@@harborareatech310 Thanks for the quick response!! I'll check and see if the evaporator is visible or not, I want to say I've tried this before and could not see it. I saw at the 12:30 mark, a small white plug-looking thing. If I can't access the evaporator, I'll check to see if that is a plug and reply back. Thanks again and hope you are able to enjoy your weekend and not have to work like me, lol
So I was able to access the evaporator by removing the glove box, etc. I removed an adapter that was used for the floorboard a/c and from there I could see right into the evaporator. The only thing is you have to have the a/c settings set to Floor before turning off the vehicle so the floor port opens up. After that, I was able to spray the foam cleaner in there. What a difference. So glad I found your video! Thanks again!!
What did u do to get rid of the smell?
Mine does that when I turn the ac on
@leojohnwayne1422 after I took apart my glove box and everything above, I used Nextzett Klima Cleaner. One can was more than enough. After I did this, my a/c had zero smell.
Hello I just took my RCF to the dealer for this same issue, looks like it’s not covered under warranty anymore. I have trouble codes B1441, B1443, & B1453. They said the dash needs to be removed as well is there anything you recommend to avoid that or which servos to replace
@Loudbasshead_ I don't remember the RC-F off the top of my head, but I believe it's similar to RC. If so, it can be done without removing the whole dash . Accordimg to the codes you gave me, you have 2 servo motors on the driver side, and one on the passenger that are at fault. I would recommend changing only the servos triggering active trouble codes
@@harborareatech310thanks for the reply! Would you happen to know which ones exactly to buy and replace Lexus is charging over 2800 and sadly out of warranty with the CSP
great video , by the way did you unplug the battery?
Thank you! Yes, prior to performing the removal and replacement procedure of the servo motor, the battery must be disconnected, as seen in 8:47
Thanks!
No problem. Thank you !
WHAT KIND OF TOOL DID YOU USE TO REMOVE THE PHILLIP SCREWS ON THAT LITTHE BOX CAUSE I HAVE NO ROOM TO REACH TO IT , HELP PLEASE
1/4 in Ratchet with a phillips socket and a bit wrench ratcheting tool. My bits are magnetic, so it helps a ton
7:55-8:55 i show the tools i use
Are the 3 motors shown in the video during the repair accesible to replace without removing the entire box? And for the driver side as well? Thanks in advance!
Yes
I brought my 2015 IS350 in for this exact issue... Just was called that it is $2400.. The only difference is it is the drivers side... Looks like number 6 from your document.... Question is.. Can this be done without that diagnostic tool that you have? Looks like it needs to be reset/programmed after the new one is installed.....
You can replace the servo motor yourself, always refer to the stored trouble code in your vehicle to know which is the servo motor affected. You may have better results after just replacing the affected servo motor, but in order to have the optimum A/C performance, the initialization is required.
@@harborareatech310 Thanks.. I just ordered a cable from Amazon and when it gets here I will download the software and try to use it that way... I am also trying to get my service advisor to call me back.. Have read a few things about how long it should be covered.. I have had this at Lexus 3 times already for this over the years and all they have done in the past was to "reprogram" the computer.. Seems to happen every year when the AC is actually shut off for a few days.. South Florida we use AC a lot :)
@joelee5493 thats a good idea! in order for it to actually qualify for the extended service campaign repair, the servo motor troble code needs to be stored and active after the reprogram. sometimes, the reprogram takes care of it. Maybe that was your case in the past. From what i noticed, hot areas are affected the most by this issue.
@@harborareatech310 After the cable gets here that is the plan. Since this has happened before... question is, what bad would it be if replaced them all since the dash will be taken apart already??
@@harborareatech310 I will try it just in case.. If it doesn't work I still take the dash apart. Not looking forward to that but it is def better than paying $2400
Thank you so much for this video! I have a 2015 Lexus IS350 f sport and have the same problem . I will order a new A/C Servo Motor and do it... btw What scan tool you are recommend to buy? again thank you so much for the GREAT video.
Thanks for watching. I used the vehicle manufacturer scan tool (techstream) in this video. If you do not own a scan tool, i would suggest borrowing one or looking online "how to download techstream on a laptop " and just buying the data link connector to connect to your vehicle.
@michaeldao1711 I have the same year and model.. can you pls let me know the part number that you ordered (A/C Servo Motor) for Driver and Passenger side ? thank you in advance
@jonatbass1111 part numbers vary. it all depends on the active troublencodes that are stored in your vehicles module
B1446 (do I need to change this?), B1453 (D), B1454 (P)
@jonatbass1111 these parts are for IS models 2014and newer b1446 part numer 87106-30570 location is driver side lowest servo motor on the hvac box.
B1453 part number is 87106-30610 location is on the driver side middle servo motor on the hvac box. And b1454 is the same part number as b1453 but is located on passenger side ( the one i replace in the video). For location you can refer to 7:29 of the video.
Hello, great video. I was wondering if the process is similar on a 2013 GS350 AWD. I have a code B1443 and dealer says $2400 to replace bad servo motor. I missed the recall period because I wasn’t aware of the bulletin. Is that motor also accessible without pulling the dash? I would love if you could do a video on the GS350. A few other members in our GS facebook group is also interested in this. Thanks.
Hey, thanks for watching and the comment. I will try to answer as best as i can. It has been a while since i ve replaced that one. But i believe you can do all servos on the GS 350 without removing the dash. That is the largest one on the driver's side, and i believe it is the same concept as the one in the video, if not very similar. If the opportunity arises, i will make a video. If you are local to the los angeles CA area, i can make a video for the GS community.
Wow, I’m so impressed on your quick response. I wish I was in LA, but unfortunately I’m in Boston MA. Any additional information on how to replace would be greatly appreciated. If you know the part number for the servo motor would also help. I’ll also check in the user group if anyone having this issue is in the LA area. Thanks
@@harborareatech310can I please get your address
Hi you guys. I'm in South LA and I need my servos serviced. Can I volunteer my 2016 gs for the video? Thanks in advance regardless. Great video bro. 👍
Hello. Do you happened to know where is the mode servo piece located at. Im having issues with my 15 lexus rc350 with the mode switch not properly working right
Give me a trouble code, and that will give me moe info to answer your question.
Any chance you have a video on how to replace this for a 2015 RX350?
I dont at the moment, but when the opportunity arises, i will make a video.!
@@harborareatech310thanks man 👍
Does this cover the servo motor problem im having with two motors on my is 250 2014 f sport...the dealershp wants 3k for repair...91,000mi on vehicle
Check with the dealership some vehicles have an extended warranty
Dang! I will always try to avoid the STEALRship 😂. Sometimes you have no choice..
Wow 3k dollars sheesh, I have 58,000 miles on my 17 is350. Thank God it was covered by Lexus warranty.
dont you hate when people bring cars in with low fuel and sometimes they ask why didnt you fill it up
Yes i do
I am having this problem in the driver side vent. Any advice?
First, check with your local dealership to see if your vehicle either falls under the technical service bulletin or service campaign. If it does, then the repair will be covered through them. If not covered, then you will need to obtain the trouble codes recorded in your vehicle in order to see which servi motors are affected
How much does it cost to replace air conditioning servo motor for is 250 ( 2010)? Thanks
Depends where you take it!
Hello ,any chance you can help me by pointing out where to find B1443 servo on RHD/UK model,is it passenger or driver side?I sourced the code and it's 43 displayed on the climate control , symptoms no air going through console vents and no memory stored for AC.Thank you in advance.
What kind of vehicle do you have?
@@harborareatech310 2014 lexus is300h,as mentioned in my previous comment it is UK model. From what I could find it looks like AC unit has to come out to access this particular servo , according to the lexus bulletin.Thank you for your reply, appreciate it .
@@harborareatech310 just a quick question , according to service report from August 2018 the fault was already there,no air blowing out of the vents ,it only blows on the windscreen,feet won't get air too.I am the third owner ,first owner had this issue diagnosed while the car was 4 years old and 62 k miles on the clock by Lexus .Do you think I can have a foot to stand on and try to chase them to fix the issue? He paid for extended warranty and there are loads of service reports but none about this issue being fixed .
@michalnowak3558 I'm not sure about that vehicle. We dont have that model over here. But if it's anything like the IS350, it will be on the driver side top servo motor, which is the biggest servo motor. It can be done without removing the whole dash, only the driver side knee air bag, and a couple of covers need to be removed. You can try to contest the issue at the dealer, and if you are persistent enough, they might goodwill the service, but it is not guaranteed.
My servo motor went out, Lexus dealer fixed it free of charge due to servo motor falls under part warranty.
Nice!!
@@harborareatech310how do you avoid dropping the back screw?
@@gomezpmm302 balance. But if you have a magnetic bit that helps a ton.
No labor cost ?
Nice video, I have a 2016 gs350 driver and passenger take turns being hot, cold or won't blow at all. I did replace my battery about 6 months ago but i didn't notice a problem right away. I noticed it after being out of town for a couple weeks without using the car. You said the servo motors are supposed to be re-initalized, does that have to be done at the dealer or can i do that another way like with a Blue Driver obd tool?
I would check first to see if it is covered by the dealer. There is a secondary coverage customer support program that a lot of lexus vehicles fall under this program. i believe it's 7 years from the date of first use or 125k miles, whichever occurs first.
To answer your question, though, a more advanced scan tool is required to initialize the servor motors. You can always download the lexus/toyota software "techstream" on to your laptop by looking it up. You would just need to buy the obd cable to connect from the laptop to the vehicle.
@@harborareatech310 Thank you, really, thanks it's appreciated. Obviously you're a good tech with a knowledgeable and accurate answer.
I guess even if I bought a servo motor, there are multiple and I wouldn't know for sure which to buy?
And lastly, even if I get the right one and I replaced it, then it won't work right because it needs to be initialized?
@mattdi333 you need a scan tool capable of retrieving trouble codes from the body control module to determine which servo motor is at fault. After replacing the servo motor, if you dont intialize, you won't experience optimum perforformance
@@harborareatech310thanks again, it is much appreciated.
Subscribed also, good content from a good guy.
I have a 2016 so I have to pay, I’m only at 60 k miles tho 😢
So you are saying, even if we replace the servo. The car still needs to be taken to the dealer for programming?
No, if you replace the servo, you just need to make sure you are equipped with a scan tool capable of performing an ac system initialization. For optimum ac performance
@@harborareatech310

@Vergitas623 If you catch it in time the dealer should cover it according to the bulletin/service campaign. If not it can be a bit costly. Always consult your local dealership for more information before anything!
@harborareatech310
Dang... I'm SOL. Mine is a 2016... 80k. Haven't had much luck with the servos... I'm in Arizona so the plastic are always falling apart. Replaced 2 of them on my Jeep and the Lexus IS just took a shit.

Thanks for watching. Unfortunately, i can't send the repair manuals. I dont do it the repair manual way anyways. The repair manual asks to remove the whole ac box, which is labor extensive. I do it the work smarter, not harder method.
i have a 2019 lexus is300 with 16000 miles and have this exact problem..do you know if its covered under warranty.
Call your local dealership to find out. They can look up your VIN number and find out. It might fall under the 4 year 50k mile basic warranty
