Rear Heat

    I just purchased a 2005 Trail Blazer LT. For some reason the rear heaters in the roof are blowing cold air while the floor is blowing hot. Why is this?

    I'm not familiar with that issue. Are you still under warranty? Get it and have it checked out.

    Scophin, I have a 2006 with the same problem it must be common. Once I find the truck warmed up I'll turn it on and it seems that the cool air blows itself out and is replaced with the warm air. It seems strange but it works.

    Oh, it's like for a few seconds? It's probably similar to my bathroom's hot water. Takes about 30 seconds of cold water before the hot water gets there. :) yikes.
