Anyone have a diagram of the auto hvac system? I'm having a hard time diagnosing why I have no heat on the passenger side. The passenger actuator was replaced. I'm thinking the driver's side blend door is shot.
Do you know of the part number?

Re: Blend actuator driver's side
Did you calibrate the HVAC motors after you replaced it?

- Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, select Instrument Panel Module.
Select Special Functions.
Select Miscellaneous Test.
Select Recalibrate all Motors.
Select ON, wait 30 seconds.
All counts will display zero and slowly the scan tool will begin to show counts.

Remove the battery positive voltage circuit fuse of the Instrument Panel Control Module.Wait 60 seconds.
- Important - The module memory will not clear if the battery positive voltage circuit fuse is installed in less than 60 seconds.
Install the fuse.

I looked at the fuses, and the hvac solenoid isn't there. I would think that needs to be there since I have auto air.
