First, Turn The Air Conditioner OFF!!!

Sorry, I couldn't resist. But I think the resident gearheads here are going to need more info here. What is the make, model, and trim level of your car(some of us have other H-bodies) and put that in your signature. I would start with checking/replacing the thermostat. Do you have the electronic A/C in your car?

does your temp gauge go up like it should?
if so, sounds like a climate control pcm fault

Is your engine coming up to the correct temperature? Is it overheating?

Does your climate control display blink when you turn the car on?

If it blinks at you for two minutes before resuming a steady temperature display, it'* got an error code (one or more) stored that it wants to tell you about. I don't recall the procedure for dumping codes from your year of car, but we should have that info around here somewhere. You definitely need to see what known problems you have first, before looking to find hidden ones after that...

P.*. Just so no one gets confused, I'm talking about error codes stored in the climate control system, not the engine'* computer. Two different systems, two different sets of error codes...

Only the dealer can get the codes from the 95 Bonny. (Or maybe someone with a Tech II)

I'm not sure if this is a possibility here but I found this to be true a long time ago and another member found this to be true not too long ago. LOW COOLANT will give you NO HEAT!!!
