Blower motor question 2000 Chevrolet Crew cab Dually
 

The blower motor on my truck stopped working last week....checked the fuse and it was good. Came out a few minutes later and it worked fine....quit again in the middle of the week, yesterday it worked fine. Today it doesn't work.

WTF should I look for as the problem? ...I'm thinking maybe a bad connection ?? Any help is appreciated greatly.

Probably the blower motor. Next time it does that try thumping the blower, if that makes it come on replace it.

I think there is a resetable relay in there somewhere in those trucks. I think I have heard that somewhere. Age is getting to me.

Also, does it do it on all speeds or just one or two of them?

That's it. Did exactly that...thump with the fist and it came on.

Thanks
