My 2004 Envoy XL rear will not work. The blower works and cold air comes out but no heat with the front or rear controllers. I suspect it is the blower resister. Where is the blower resister located and can this be the cause of the problem?
One of the second heater core lines is clogged.

Same problem. dealership says i need to add a pump to pump the coolant to the rear. Problem is, it blows warm air in the summer and cold air in the winter. problem isnt getting coolant back there as it was working until recently. doesnt seem like I should add a piece to get it working how it was working without it in the first place.
It's a 2004 there's no heating what so ever what would cause this
the heat blows cold air in the rear vents and no heat is blowing out of the 4 vents above the heads
My blower on my heater only was working on high, but now doesn't work at all. I replaced the resister, but still sounds like the fan is trying to go but can't.
