Question about 1999 Pontiac Grand Prix
Does anyone know where the outside temperature sensor is located on a 1999 Pont. Grand Prix Gt. My outside temperature gauge is ready 31 degrees even if it is 100 outside. With it reading at 31 degrees it does not allow my ac to turn on. I have heard that it may help to move the sensor, but I do not know where it is located under the hood
The sensor is located near the hood latch area in front of the radiator. If the temp is reading incorrectly, chances are it is defective. You can purchase a new one, they relativly inexpensive.
Disconnect the electrical connector then remove the sensor.
Good luck, let me know.
