Hvac blower motor stopped working replaced resistor and blower motor. Checked fuses and relays all good. No low voltage reference on briwn wire ?????????? Don't have any idea whats going on now. I've been working on it for ten days

'TESTING' all of the fuses takes approximately 10 minutes - or less! .. Also look closely at the wire harness connector @ the blower motor resistor module for any signs of melted plastic or blackened terminals .. New connector is available. (Same vehicle as Chevrolet Trailblazer)

Hi pushrod my name is Bo. Yes sir I know that there is the second fuse box under the rear seat all the relays and fuses in both fuse box's are good. The abs and brake light are both on as well I also used a solus snap-on scanner and a matco non impedance test light that's why I'm thanking ignition switch thank you for all your help

Considering the other electrical issues - I think you are on the right track! .. Have seen this on the Trailblazers.

Thank you sir thats what i was thinking. I've been working on these dang cars for 30 years but sometimes a person needs some help thank you again for your help

I know exactly what ya mean! .. I've been at it 43 âž• years and still need help - when I can get it. The main thing is just being persistent!

Thank you sir have a good day
