The A/C system is likely low on refrigerant, which means there is probably a leak in the system. The evaporator is a common place to find a leak on this car, and unfortunately it's a very expensive repair, 8 hours labor +parts, so over $1,000 (if that's the problem). Many people just add refrigerant and it will last for a few months, enough to get you through the summer.
If the lights on the controller are flashing, then you have another issue and it would need to be checked out.

Try shimming the compressor with a bread bag clip. Look it up on line first to get the particulars.
