The climate control for the driver side won’t work. Any tips or do I need to replace the whole control panel? Thanks.

 

Define "does not work at all". Does air blow out of it? Is it hot or cold?

As for what it could be:
- Bad Hvac control panel
- Damaged wire
- Defective HVAC module actuator (usually it makes a clicking noise when you adjust the temp)

In my 2004 Monte, the driver side never really blew cold air. I had to rip the dash out and pull the HVAC module in order to replace the evap core for my AC at one point. During that, I found an issue with the flappers that control the dual climate AC. The one did not move well because the hinge point for it was too stiff. I used sand paper to worked down the one post just a couple hairs. Put it back together and all is great!

 

When I slide the **** from cold air to warm air it stays cool.
