How to fix a blower motor that won’t turn off and has no speeds 

I have a GMC Savana that I parked awhile ago.Went to start it..battery dead.Hooked up cables..yep..blower fan is running.Would not jump start.Battery conpletely drained.Going to try pulling the wires to the blower.Or pulling the fuse.I'll try and charge the battery.I have no idea yet where the relay switch is.

So mine would turn on whenever it wanted to and only be at speed 5. It was draining my battery. I replaced this and it didn’t fix it. Changed the fuses as well.

Did this, my blower still blows with key off. This is a fix, but not the fix for me.

I replaced that and still stays on

Great video easy fix. Bought same product and blower works and turns off now. Thank you

Pls change ur resistor block located near blower fan

Dude, thank you for the video and the link... I have AC again.. God bless

Fantastic video, great job. Informative thru every step.

Same if it's back blower? My front needs replacing

Thank you Sir, mine just happened...

Thanks a ton great video

Testing a new resistor because my 12 won't turn on. Trying resistor first. After installing the new unit, the blower won't shut off lol. Think I'll just get the "troubleshooting bundle" on rock auto and be done with it.

Thanks 👍

Thank you

Thanks

Will this help the blow fan ?

Mines did that but after I started driving for a few and shut off the blower was back running again

Will this module work on the rear blower in a 2003 Tahoe?

Will this work on 2003 Chevy Tahoe

Has anyone had a problem that sounds like the vent won’t stop switching air current from the defrost to vent over and over on passenger side? At least that’s what it sounds like I haven’t confirmed that’s the issue. Know how to go about diagnosing that?
