Question about 2005 Pontiac Montana

2005 Pontiac Montana SV6 heater blows cold when slowing to idle

Our Montana Van warms up fine and blows hot air when travelling on the road. When the car slows to an idle the fan blows cold air. The temperature gauge is in the correct position and the fan speed and volume does not drop. The dealer is telling us this is within specs. We have had the van from new and never had this any other winter.

How cold is it there and does your engine cool down any while going slow? If it does it may mean you need a hotter thermostat installed, My first thought would be to check the coolant level in the radiator and the coolant reservoir! Hope this helps and Merry Christmas

There is a flap in the venting itself that can get stuck. Or the actuator that moves it can become faulty. It is located above heater core and it's housing. You will have to remove bottom console to access it.

For the sliding doors you need to clean the contacts, there are 6 or 8 on both sides, just wipe them clean as they are probably covered in oil/grease/grime.

No rear heat in pontiac montana '99


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.
