Air Conditioning problem
2000 Chevy Venture 4 cyl Two Wheel Drive 125000 miles

A few days ago the check engine light turned on, the air conditioner suddenly stopped functioning properly, and the van started to over heat. The air conditioner will only blow out hot air, and about 4 months ago I had the refrigerant refilled at an auto shop. I have no idea whether this has anything to do with the check engine light turning on or the over heating but any ideas on why the air conditioner stopped working? Thanks in advance.

The "check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.

Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.
