hey dude. did you ever figure out what was wrong with your blower fan? I'm having the same issues...

There is a small panel inside the car. To the right. Passenger side. Right under the stereo. Remove the panel and check the blower motor fan fuse there.

mine is still not working. I replaced the fan motor, the resistor, the relay and the blower switch. all of my fuses test good but, I still get no power going TO the switch...

You removed the small panel on the passenger side and checked all fuses right?
Another guess is a short somewhere going to the ac / heat knobs module

found the problems!

first of all... there are TWO fuses under the hood for the BCM (body control module) one 30 amp, one 40 amp. Even though it wasn't "blown"... the 30 amp one was bad. this fuse is apparently dedicated to the blower HVAC system because nothing else was affected at all.

second. if the blower switch on the dash is bad, GM will charge you $125 to $150 to replace the whole hvac panel. the blower switch itself is not available. SO! before spending the cash, I carefully bent up the ears on the back of the switch and opened it up. Now.... the contacts are spring loaded BUT!! there was SO much grease inside that switch.... as the contacts wore slightly... the grease held them apart because it had nowhere to ooze out....

AFTER wiping out all the excess grease, losing the little BB that positions the knob, finding the BB again... : ) I put it back together and POOF!!! works perfectly!!

The HVAC panel float around for 50$ lol. There's plenty available

I had the same problem on my 2007 cobalt and it was the simplest thing I could possibly imagine. I bought a new resistor, switch and fan and when I was just getting ready to install my fan my hand bumped some wires and it turned back on! Been working fine ever since. If it's not anything like the fan , switch , ect... And you're getting power just follow the wires and make sure you don't have a short! Saved me a lot of money and hassle because those blower fans are NOT easy too install
