Problem with ac function because of an error in the external air temperature sensor in your Grand Prix gtp 99?

The computer monitors the outside temperature through the sensor

and will not activate the a/c when the temperature reading is too

cold. It is not an expensive part but shop labour can be expensive.

With the sensor replaced and reading proper the a/c function should

return to normal. Hope this helps. "G"
