My 2002 envoy blows cold air out the driver side vents and hot on the passenger side.
I have changed the climate control module with a brand new one and Im still having a the same problem. I purchased the new one and it was blowing hot for a few minutes then turned cold again.
Any idea what this can be?
Temp actuator?
Mode actuator?

Drivers side temperature blend door actuator. On most GMT360 this is the same part# as the defrost actuator. The blend door actuator is located naturally on the drivers side footwell/console area. There are 3 actuators on the drivers side. The blend door actuator is the rearmost one and the most difficult to get at. There is some metal bracketry in front of it but it can be changed without removing too much.
