I never see the bottom part move.
Thanks for video
Thank you so much!
Awesome video saved me some money. All I had to do was clean off the excess grease like you said and it was back to normal.
Thank you
Excellent help thanks! Plastic clips snapped off when pulling appart but you can very easily tap an M4 thread into the four unused holes on the long side in the casing and use screws to reassemble. Almost looks like thats why the holes are there!
What is year and make of car. I have 1999 Camry and the a/C door actuator is supposed to be driver's side, unlike other model years which are on passenger side. I simply do not see posts or videos about how to find it on this gen4Camry
Excellent video, one question, to remove the servo, do you have to remove the board?
Innova Solar Ac. Di setel keluar angin gak dingin??..klu di gas baru dingin ?...
Is there a part number for this servo? I was told there are 3 servos.
Which servo motor controls the air direction? My 2002 4runner is stuck on torso, will not move to defrost, etc. There are no clicking noises and it selects from heat to ac.
Is this also a blend door actuator? I have replaced my compressor but still doesn’t blow cold air. Can this part help fix the problem?
You might need to see if the evaporator has been clogged. Cleaning it will make a huge difference in cooling.
Very insightful video man. My car has a 45 seconds delayed HVAC start. The ‘Auto’ mode is lit for the whole 45s but no HVAC control works. Could it be the lower servo?
The same as I have. AC delays when start up for 45 second. This arose after replacing rear AC and amplifier (both are used parts not new).
These codes appeared:
B1447 Air mix damper control servo motor circut (Rear)
B1443 Air outlet damper control servo motor circut.
Could you help me?
@@bujabal76 Hey, in my case it was the mechanic's fault who put the servo motor back after cleaning the evaporator. I believe the car's ecu checks for the whole 45 seconds why the problem is occuring and then finally bypasses the checking process to run the AC. I took my car to Toyota and the technician told me that the mechanic who worked on my car did not align the gears of the servo motor with the flaps's arm. After the Toyota technician did what he had to, the problem is gone. The AC starts right up. Also, the servo motors on Toyotas are made by Desno and so they do not fail that easily. I would advise you to check whether your servo works when you switch from Recirculation mode to fresh air mode. Try to listen to a flap opening when you do so. You will feel a sudden decrease in air flow through the vents as well. If you hear a noise but with the flap not opening, you have probably been affected by the same problem I had. Take the motor out, dissassmble it and clean the interior of the housing keeping in mind the position of the gears and motor polarity. Check it this works. If not, then you might need a new servo motor. I wish you good luck, friend. h
@@sauravparashar8016 Thank you for the explaining this clearly. I have done as you said but no noise coming from the dash. I doubt the technician has missed to put back some wires for the servo motor when he was checking for the issue that caused the AC to failure. It was a bad amplifier
@@bujabal76 I am glad that you sorted the issue out. Cheers!
@@sauravparashar8016 Thank you for your contribution. My vehicle had a 45 sec delay before the AC system starts up. Following your guide, I took the vehicle back to the technician and he was able to align the gears of the servo motor with the flap's arm. AC system now ready for operation immediately the vehicle lights up. Grateful.
Could a bad ac servo motor affect air flow? My car has low air flow on full blast and idk what it could be. New air and cabin filter, no clogs anywhere i can reach, not sure what else i can do. The fan sounds fine too
Nope, servo just controls the direction of the airflow through tunnels, Like it acts as a valve to opening, closing, and changing the flow direction. Maybe your evaporator inlet is blocked (Outside Air Inlet).
@@LahisTechLT ill look into that, thankyou much!
@@aquamayne8168 In my case, it was a clogged evaporator. But now, after I cleaned it, my servo motor is messed up.
@@sauravparashar8016 if your car is newer Lexus should have sent you a letter in the mail for servo motor going bad too soon, and will repay the xost it takes to fix it. I would reach out to Lexus dealership and see if your car qualifies
@@aquamayne8168 It’s a 2009 Corolla that I have. And so, my luck has just run out! Haha
what kind of grease did you use?
You need to lubricate it after clean up. Because it will wear out.
It was lubricated using silicone grease. No need to lubricate it with too much of dielectric grease that's why I wiped it out the excessive. Thank you for the comment.
Looks like nothing solved the 2nd motor still stuck!!!
My l hve yr location to repair aircon problem one size hot
It sure doesn't look like you are working on a 98 Toyota Camry... How about a little more info on the car you are working on!
avalon 2002
What the name of the car toyota land cruiser 100 series or what
Toyota Sai
Contact no.send kar do bhai
Mere pass innova 2.5 v top model hai
Ac ko chalu hai per
Auto system nahi chal raha hai or link problem bhi malum nahi per ri hai kuch bataya
Yh contact no. Send karo do plazzz
So it didn't work?
It worked.
@@LahisTechLT The bottom servo lever didn't even move?
@@jjack6896 it worked, I was unable to change the "A/C MODE" while filming to show that the servo lever movement. Sorry.
was kind of moving with hands the lever?
@@LahisTechLT hai.. which button should i press to test lower servo moving?the video show upper servo was functioning.. how to test lower servo was working..?Tq in advance
My motor is seized. Where can I buy a new motor?
