Hey yal my blower stopped working up front-rear works fine.

Checked the fuse on the passenger side- along with just about every fuse in the drive side and engine bay. They all tested fine for continuity.
I currently have no power to the blower.Checked the negative and positive leads on the cable going to blower with a DMM as well as the connection on the rail.( there is a short run where the hot goes into a connector then up in the dash out of sight-hooked hot end to DMM and grounded other end to vehicle to test)

It has no resistor which I wasn’t aware of until after I looked for it for 2 hours.

I can here the vents open and close when I change directional settings. I can also hear something actuating when I turn the power on to HVAC unit up front. But still no power.


That’s all I got.

Any help would be appreciated. Chevy wants to charge 120$ just to look at it.

what I would do is (only do this when you know you'll have access to the car all day and you are also free all day) go to AutoZone and buy a blower motor. install it, see if it works. if it doesn't work take it back and you'll get your money back and you are dealing with a bigger problem. if it does work, then it was the blower motor it self.

He stated no power to the blower motor, so not the motor.

Spend $20 at alldata for a one month access to a real shop manual so you can properly diagnose it.

Jump 12v to the motor to prove it works, then you can continue with your diagnostic challange

Did you ever figure out the issue? Mine is doing the same thing.
