We can be helpful. When you get a chance, listen to see if the compressor cycles. If it doesn't, it could be a low pressure switch gone bad. All the switch does iskeep the compressor from running if it doesn't haveenough suction pressure so it doesn't crater itself.

 

Spartan: Stupid sounding question I know, but you do have enough coolant in the car?

My car's heat didn't want to work for a couple of days, and I found out it was because the coolant was too low. I'm lucky I didn't tear anything up (intake manifold gasket was gone and the engine was consuming coolant - 3800 v6 for me). Engine would get nice and warm (read "Hot" according to the guage) until something would "burp" in the car and the remaining coolant would start circulating.

So check the coolant level, and if that's OK, I would expect a Thermostat as the next culprit, either stuck open or stuck closed. Does your engine temperature guage move at all? If it never moves off of stone cold, then you're not going to get any heat in the car either and I would strongly suspect a stuck open thermostat.

 

Yeah, i just had an oil change etc and they topped it off for me, but they didnt flush it or anything... As far as the gauge it will jump around in the bottom 1/2, it ususally doesnt go past the middle line.
