Driver side heater goes hot but not cold (It's not the servo)
Problem: My driver side heater only blows hot air and not cold.
Background: thieves stole my radio along with my climate control and cut the wire harness. I purchased a new climate control unit and oem wire harness and reconnected everything back using butt splice crimp connectors. Then I noticed my driver side heater only blows hot air regardless of my temp setting.
What I know:
- It's not my driver side air mix servo. I tried 3 different driver side air mix servos and they all act the same. Changing the temp from cold to hot on the climate control moves the servo white arm towards the hot direction, but not vice versa.
- It's not my climate control. I just purchased a 2nd climate control and the problem persists.
- Let's leave the passenger side temp out of this case (I know the servo is dead and stuck on cold)
- All of the buttons on the climate control work
I'm guessing I did a bad job on reconnecting the wire harness for the climate control. Is there a wire diagram somewhere to identify which wire(s) control the 'temp down' button? This would be helpful before I have to test the connection for over 30+ wires one by one.
Any thoughts would be greatly appreciated.

Maybe your refrigerant is low. U should eliminate that before going after the parts as I believe this phenomenon occurs with low refrigerant
