The air conditioner is not blowing any air at all. All the buttons on the panel work and light up, but no air whatsoever, tried both extreme heat and extreme cold settings on the temp gauge. Its a 2003 saab 93 Arc.

Sounds like it is low on the coolant which causes it to only work part of the time. You could probably take the car to a auto parts store and at least here in the midwest, they can help recharge your freon/R22 so you have a good working air conditioner. If that is properly charged and leak free, then your air conditioner compressor might be going bad, but then you would hear a lot of belt squealing when it wasn't working. Most likely though it is just low on the freon/R22.

By the way, air conditioners don't have spark plugs......LOL

These will help.
Thanks.

sounds like the evap core id freezing up are you leaving it on recuit position to long?

Possible blower resistor/control module failure. Usually located near the blower motor itself.

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?

yes there is a blend air door that mixes a/c with the heated air and it sounds like it is out of adjustment the other thing is the heater core could be plugged

compressor or receiver/dryer or condensor may need to be replaced. Further testing will have to be done. Look into your sight glass and see if there is any bubbles in the glass, or if glass is extremely foggy. If so, you may have air in the system. Check to make sure you are getting power to the compressor.

It sounds silly but there is a separate unit in your console that you can only turn off if you go in from back seats. You probably already did that, but if not try. You can not turn it off from any controls on front panel. If it doesn't work, I would think something is wrong with the switch. Open it up and look at wire connection from switch regulator. It also has a heat regulator on the console facing back seats? Mine does anyways.

Yes go to you have to get the codes from your ATC controls first...Hold down the A/C button and the Recirculating button at the same time and while holding the two buttons turn you left temp. control up. It should give you codes if not then it will just read 00. Once you get those find out what they mean...20, 46,52,or 54 means you blend door(s) are stuck down and have to come up to allow heat to flow. Go to www.heatertreater.net and it will tell you how to replace it or in my case I just fixed it by putting a screw in it to hold the doors up....But hey i'm cheap so i like quick fixer uppers!!! Try that and lemme know if it works...

the electric motor that open the heat door looses electrical connection there by the door stays on cold / it is located under the a/c heater assembly / which requires removing the whole dash and heater assy// also bleed all air out of coolant system
there are three doors / 1/ a/c heat 2/ mode /defors 3/ recurculation [email protected]
