I have a 2013 lexus GX 460. If I set both passenger and driver's temps to the same. ie 70, the driver's side is about 10 degrees or more warmer than the Passenger side.

I'm not sure but I think that this does not always happen.

From what I can see, it might be a bad blend door actuator for the driver's side

1. Where is the driver's side actuator located? Is that behind the glove box?
2. How difficult is it to get to it?
3. I've seen threads where people try to disassemble and reassemble them. Has anyone done this?
4. Where can I find a part number for the actuator?
5. Are the passenger and driver's side the same or different part numbers
6. I did a quick search of amazon but didn't find any compatible actuators. Some people suggested junk yards. Are there any other sources and would this be avail from a dealer?

Thanks,

Chris

 

I was playing with it a little this afternoon. I tried cycling the temp from lo to hi and back a couple of times. It SEEMS to be blowing cooler air.

I'm going to try to find a replacement actuator in case it continues to give me problems. I would appreciate any help with sourcing that.

 

You need to download the service manual and go through the methodical diagnostic tree. You will need a scan tool that is capable of reading the HVAC DTC codes.

Forget about buying anything from Amazon or a junk yard. You want OEM parts for this (Bell Lexus).

For reference, here are the part numbers.

87106-60220 HVAC Air Inlet Door Actuator Left
87106-60230 HVAC Air Inlet Door Actuator Right

These parts are not cheap so I would not replace them until you are sure they are bad. It could also be the amplifier. That is why you need to go through the diagnostics.

 

Thanks - I will download the manual and go from there.

I mentioned in a previous post that I cycled the driver's side from lo to hi about a dozen times. Took a drive after that. I didn't have my laser thermometer but the driver's side was almost as cool as the passenger side. If it stays that way it buys me some time.

Thanks again.
