Did you figure it out what was wrong with your A/C yet?

Taking it to a shop will be the best thing to do if you do not have the knowledge and the tools to diy this problem. But at least you need to know what it is and it is not doing so you will not be surprised with the repair bill. Your description of the problem is very vague.

A few questions for you.
1. Doe the cabin evaporator fan runs? Does it run in different speeds?
2. Does the compressor clutch engages when you push the A/C switch ON?
3. Does the thermostat knob have any effect on the compressor operation?
4. Does the radiator/condenser fan runs when the A/C compressor button is turned ON?

Here is a diagram of the A/C system. if you look at the diagram, the compressor relay coil ground path passes thru the DME. The climate control module is also looking for pressure switch and evaporator temperature sensor inputs. It gets quite complicated. Answer the above questions and with your knowledge of wiring circuits, you can probably diy this issue.
