Your A/C unit is low on Freon, or you have a bad pressure switch. Turn on the Air Conditioner, with the engine running, & put it on Max. Open the hood, & see if the compressor is spinning. If it is not, then you need gas. You can buy refill kits at a local Walmart. If you have a leak, it may be a wasted $30. That is what I paid for a 22 oz. can of R-134A Freon. I had a dealer regas mine & put in a dye that they can find leaks with a black light. It may be cheaper in the long run. My drier, in front of the radiator has a leak. It will cost $460. to replace it.

2004 mitsubishi lancer es a/c blows hot air, already check freon its good


Your AC compressor is probably bad. There's a plate on the front of the compressor that spins when you turn the AC on. If it's not spinning when you turn the AC on, your compressor is bad.

Heat blows hot on passenger side but cool on driver's side


Most likely it is the climate control unit. Had the same issue with my 99 Regal, replaced the climate control unit and haven't had any issues since. Might try Digital Dash Solutions on eBay, they will ship you a refurb at1/3 price of buying from a dealer if they have one available. If not, they also have a climate control repair service. I'm not certain that they fix Pontiac products, but it wouldn't hurt to ask.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

I have a 1993 dakota, the climate control only blows though the window area. I cannot get air flow to move from the window to any other setting, floor or dash. Wondering what the issue may be and how to...


wakow4u, What you have to do is look for a vacuum line that comes from the engine and enters the passenger compartment through the firewall. This vacuum line controls the climate control. A small rubber hose that fits tightly will suffice as a good and quick repair. Good luck with this.

Blowing hot air on the driver side other vents cool air


disconnect the battery and try again to re sync the two sides, this is a common problem on all dual climate GM cars, if you can't get them to resync then you will need to replace the climate control head..

Climate control does not blow cool air. When I turn the temp down there is no change in air temp. It blows full hot air. Sometimes I can give the dash a smack with my hand and it will blow cool air, but...


you going to have to tear the dash apart (ac control panel) to see why your switch is not working. The control valve unit works on vacum systems and you need to find out where is leaking or the hoses is old and broke off. If your ac compessor still working and blowing cold air but does not adjust the temperature, it will be in the control valve. Is very easy to fix if you locate the leaks or a bad valves. hope that help some.
