Sounds like you have controls for each side of the car. The driver's side is not working right. The blend door maybe stuck in heat position and maybe the problem.

Sounds like you have a leak in your A/C system.
I recommend you take it to a AskPatty.com Certified Female Friendly Shop and have them do a A/C system check to find out what the problem is.

On the assumption that it has dual zone climate control, it is possible that one of the blend doors is not operating properly. Taking the vehicle to a good repair shop for an accurate diagnosis is a good idea, as depending on what is wrong part of the dash may need to be dissassembled to find out whats going on.
