Having problems with your 1999 Pontiac Montana ?
No rear heat in pontiac montana '99
\015 The back fan but no blowing warm air just cold air\011\011\011\015
Warm up vehicle, then access heater pipes that run to rear of vehicle. they should be HOT. if not you have a circulation issue. IF they are hot, then the blend door is not in the correct position. this door directs air across a hot or cold core to create the correct air temp. check and update me.
