This is the first time I am having problems with my a/c. The weather is starting to really warm up here and I turned on my a/c. It is blowing warm air. What can the fix be? I'm the one that posted a while ago about leaking antifreeze from the back of the van. I found a few leaks on the pavement near the tail pipe. When I looked underneath, it appeared to be one of the joints leaking. There are three "pipes" that run from the front of the van to the back. I was told this was the heater coil? for the back of my extended van. Could this a/c problem be now be related to the antifreeze leak? The problem is it only leaked like a few times. It hasn't leaked since. Why is this only intermittent leaking? Please help.

 

The problem can be one of many. It could be as easy as a bad fuse. It might need a recharge of refrigerant. It could be a faulty clutch, a bad compressor, a bad A/C clutch diode, a bad dash switch, or a few other things. You need to bring it in for a proper diagnoses.
