I have a 2005 Chevy Avalanche. Recently, the blower (heat and AC) would stay on even after the truck was turned off and key was removed. After running the battery dead a few times, we searched this forum and found suggestions to replace the blower motor resistor. We replaced it and now, the blower does not come on at all. Before replacing, we followed certain instructions on youtube that suggested we cut the purple and black wires because they were too difficult to disconnect. A few days later, the new resistor arrived and we were able to unplug the old black and purple wire from under the dash and install the new resistor complete, without splicing. But now, we have no blower, where previously we had non stop blower. The display works, the controls function, but no blower. We checked the fuse. it seemed fine but we replaced it anyway. No luck. I would say bad blower motor but it worked before the new resistor. My wife suggested parking it under a dead tree since last week we had to replace the water pump and a couple months ago, we replaced the transmission. Suggestions? (don't say park it under a dead tree)
