I have a 2001 pontiac sunfire. 3 days ago, i decided to recharge the ac for the first since i've owned the car, and the ac worked fine (except it wasn't exactly cold). So, the next day, i added more freon, and the compressor kicked on and the air was cold and worked amazingly. Today, i turned the ac on, and the compressor wont kick on. I've checked fuses and everything. Any advice?

Just had the same issue and posted. Just found the solution is the control module in the dash. Went to the junk yard since new is expensive on these units. Plugged new unit in, was able to charge a/c now blows cold as ice.

Several- The system should hold freon for years without leaking. There are pressure switches and they cut off the compressor with an undercharge and an overcharge. You need guages to measure the charge. There are testers the A/C shops have called "sniffers" which can detect a leak. If you have no leak then you need a technician to add or remove freon to get the concentration right. Or you need guages.

Check the A.C>Relay or It could be low or leaking freon

SOURCE: AC doesn't blow cold air, but refrigerant levels

The low side pressure seems ok the high side would help,Is your compressor cycling and is the air coming out even slightly cool?slight over charge cold effect cooling ability.I wish I could be more help. I will have to think about this one.maybe you could make sure your temp.door is actually in the commanded cold position.

the clutch on the air compressor coil is proably burnt out. disconnect electrical plug at end of air compressor and supply current direct from battery to see if clutch engages, if it does not, change thecoil clutch switch.
