I'm looking at this 1994 cadillac deville. The only problem is the ac. When you try and turn it on, it only blows heat on the passengers side and luke warm on the drivers side. when it turns off it still blows heat but at my feet. let me know if you can help

I'm going to give a more specific set of symptoms. This is a friend of mine.

On cold days, the passenger side blows full hot air, and the drivers side perhaps 10-15 degrees cooler. With the warm weather we've been having recently, its about the same. Blower motor still works perfectly along with everything else.

Is this a heater problem or an A/C problem? I think the A/C will be on to control humidity, but is usually regulated by a blend door. The blend door usually has some type of actuator that does the mechanical work of closing/opening the door. Check your actuator.
