SOURCE: My air conditioner won't blow cold air. It just blows air.

Hello I'm a M.B. tech. 1st you need to know why the freon is low. Hopefully it just needs to be serviced. There is a component located in the lf of the engine compartment called a receiver drier. It soaks up the moisture in the freon so the gases can work the way they are supposed to. On this unit there should be 2 switches(I believe they were combined into one switch in 98. 1 switch is a temp switch that operates your electric fans, the other is a compressor cutoff switch. Assuming the compressor is not coming on-take a fused wire and bridge the 2 contacts- If the compressor does not come on at all there is another problem(it is not low on freon. On the condenser there is a high side port(it is the bigger of the 2)By the brake master Cyl.(lf of the engine compartment thereshould be a smaller low side valve in line with the fuel cooler hose. Usually you can hook up a machine to the low port and **** freon in through that port. Assuming you do not have a refrigerant machine. It is very self explanatory on the bottle of r 134a refrigerant which can be purchased at your local auto supply store. I would start with 1 lbs. and add dye with the freon in case there is a big leak. If the system is overcharged it will not cool properly. I believe the system capacity is approx. 2 lbs. Add a few ounces after the first pound until a/c system is cooling properly and the electric fans are also coming on when the system gets to high. If you get a can with a good Gage set on it you should see the high side between 150 and 2000 psi(fan coming on at max. press.) also the low side should read about 35. It is about the temp of the evaporator which is i=located in the dash and the blower blows through this component out through the vents. Hopefully I have been helpful.

SOURCE: air conditioner isn't blowing cold air

Could be a number of things...electrical connections causing the compressor not to run. Turn on AC and turn your thermostat all the way to cool...now visually check to see if compressor is engaged and not just free wheeling. Most likely you lost your refridgerant due to leak in the system...would need to find leak and repair then have your system re-charged with refridgerant. Best case scenario...your system just needs a charge of refridgerant due to not having enough.

If the fans are working that means the a/c system is operational. Try letting a little freon out while the a/c is on and see if the pump stays runnig. If so Shut the a/c off, drain the freon and replace with r134a and enjoy

How do I check the Air Conditioner spark plugs in my 2002 Malibu?

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

Air conditioner suddenly stops blowing cold and starts blowing heated air. Control panel indicates that it is still on air conditioner. Switching the control from vent to cold does not have any effect. ...

If you are absolutely confident the AC compressor is not kicking out on low pressure then it is the blend door actuator.

The blend door determines how much air blows through the heater core or evaporator.

The actuator can be purchased at dealer and maybe at a local part store.
