So i have warm air coming out driver side and cold air out of the passenger side - pretty common problem from what i have read but no actual video of a fix on you tube. I have codes 24 and 42, the 'diagnostic code identification' list that is on this website doesn't have code 24. i did check the codes in the dark and i also read that it could be the sun sensor but i got a code 21 and that was listed as the sun sensor - so why is 24 also sun sensor, oh well.... but what i am really concerned about is code 42 which is air inlet door servo part number 87106-33260 which if i am not mistaken is also Lexus denso part number 063800 - 0172... can someone tell me where this part is located? Is this the correct part that i need? Any videos. Please Please help. I am desperate - i live in Florida and summer is coming

btw i have checked coolant levels, i did recently change the cooling fan module and i never disconnected the battery while i did it - fyi

It is located above the gas pedal.

With the ignition on watch if there is any movement on the actuator by changing the temp.

P.S. Does you AC compressor engage?

RodeoRob

WOW, thank you for replying - for real....... i get code 42 which is the air inlet sevo according to the codes that i found on the forum and other video show it is behind the glove box (i pieced two videos together to locate it and figure out how to change the more difficult one).... i want it to be the servo next to the gas pedal...So i thought the one located next to the gas pedal was just changing the air from floor level to vent level. But you telling me to adjust the temp to see if the actuator moves gives me the impression that that servo next to the gas pedal does effect temperature - can you confirm?? that would be so much easier. either way that is happening tomorrow (maybe today)

Yes compressor engages

and please anyone feel free to reply to thread, still a little concerned if i understand code 42 since, i am conflicted about which servo
it is not the big disk looking servo though i hope, correct?

Thankyou for this it's nice to have these threads all in one place

So i checked the servo next to the gas pedal and that is not it

I gave you the position of the servo motor that I found through the part number that you gave me.
That is the servo motor air mix sub assembly.

So if that servo motor works then we should look at something else.

On the other side check for these two:




Note: they might move but the shaft can be broken so check if the door moves with the servo.
