So last week i started my truck and no air was coming out of my vents. I could feel heat but it wasn't blowing. I brought it to the shop and they were able to fix it. They said it was only a fuse and they replaced it. But the next day it stopped working again. Again i can still feel heat but it's not blowing. And i can't get in contact with the guy that fixed it because he's not in the shop on Sunday. I'm wondering what the problem might be. I tried putting in a new fuse but it didn't work.

Blower motor resistor more than likely. is more than likely burnt to shit...mine was like that. started noticing the lower fan speeds were gone, then finally replaced it when i lost speed 4. quick and easy job and the replacements are made better to withstand the temperatures. i think ceramic as opposed to a bare computer chip
i'd rather replace it myself then let the dealership jack with my stuff. I took my truck in under warranty for a bad headlight switch...told the tech it was bad (dash lights wouldn't illuminate) he told me to let him handle the troubleshooting. 2 hours later as i'm sitting there, another tech comes out saying they couldn't figure it out. i told him what i told the other tech. 10 minutes later he drives my truck around all good to go. stupid entry level gm tech was a cocky little shit. so no thanks, i'll do my own maintenance.

good luck with the's easy
