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.

If it had to be charged, it probably has a leak. Check low side pressure. If low, repair leak and recharge. If pressure is good, please get back to us for next troubleshooting step.

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.

2005 Pontiac Montana SV6 heater blows cold when slowing to idle


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

2004 Pontiac Montana blows cold air in defrost


There is a mix damper inside your duct that controls the heat over heater core and ac evaporator that to your floor and one to your defrost. it is probable an electric actuator, that is not functioning properly. If yu can locate it and manually move it, you might have to remove the actuator motor first, you should be able to figure out your problem, I hope this helps! merry Christmas!

2000 pontiac montana heat issues


Try checking the cabin air filter, if equiped. It may be clogged making it draw more cold fresh air. Check your owner's manual to see if you have one or not, and it's location.
