When set to heat on vent, heat does not flow like it does when it is blowing cold air. When the heater is put in bi-level position it becomes extremely loud and sounds like the air cant get out when put in heat setting. When it is extremely cold the car does not heat properly. Have had this problem looked at 3 separate times, 1st incident told that this was normal, second said they "fixed" it after a meltdown (smelled plastic burning) in the heater controls, now saying there was a tsb related to this problem that they were not aware of and will follow it accordingly. If not, we are seeking help via lemon laws.

I am not happy with the heater in my 2003 Rendezvous. I have been to my dealer, talked tobuick and also a field rep.(david brie?) I am not happy with answers I have been given. I am not the only one that feels there is a problem. When the heater is put in bi-level position it becomes extremely loud and sounds like the air cant get out when put in heat setting. When put to cold setting the air flows freely. All my other past vehicles never had this problem and when it is extremely cold the car does not heat properly.
