Question about 2004 Pontiac Grand Am
I have the above car and am having heating problems. When the car is sitting idiling and the rpm's are low there is no heat. When i put the rpm's up to about 1200 or so and keep my foot on the gas there is heat? If I let off the gas I loose my heat. Could this be the thermostat stuck open? Thanks.
Thats a good posibility when you hold the rpm's up you get more water flow through the heater core i would start with a new stat and go from there. Its also a good posiblity that the intake gasket is out or leaking
