98 Olds Intrigue A/C Question
 

I'm having a problem with the A/C for my 98 Olds Intrigue that maybe someone here can help me with. The climate control, on the driver side, does not appear to be responding to the A/C. I get cold air on the passenger side vents (including middle passenger and right passenger vent) but only warm air from the front driver and side driver side. When I switch the air to hot air it immediately responds on both sides but the A/C does not appear to be working only on the driver side. Any suggestions? Does it sound like an electrical problem? Any help is appreciated - thanks.
