I have a 2004 Sierra 6L automatic 4X4 3500 dully flat bed I use farming and was looking for wiring diagrams to fix the blower motor and found a post on this forum I thought might be useful. Thanks for letting me in.

Yes sir. Thanks that's what I needed. maybe you know the answer to this. I doing my home work I figure out that with all the slow speeds working on the blower motor and the 40 amp fuse is ok my problem was the relay for the blower motor. I went to the parts store (AutoZone) and asked them to look up blower motor relay and they have one. It a five prong relay but no one knows where it goes. When I look at the wiring diagrams it looks like the resistors have the relay in there already and no way to repair that part. I guess my question is why would they sell a part that doesn't go anywhere? It must go somewhere. Maybe you know where it goes? I sure can't figure it out. Thanks again.

I'm thinking I may have figured it out. I haven't taken it apart yet but it maybe that they have changed the part so that when you buy the resistors the the relay is now molded in so it's not a pug in any more. If thats not the answer I'll post it here after I take mine out and have a look see. Now when you buy the resistors which is what evey one thinks is the problem you get the relay too. Thanks.
