Right on, Danny. Thanks for the information, I'll look into that as well, just to be sure.

^ Just an FYI... last winter i replaced my blower motor thinking it was shot.I installed the new BM and i still had nothing,grrrr... I did some research and talked to a few GM nuts,and found out/was told it could just be my "fan speed control switch".I guess its a fairly commen failure.I then got a new switch,installed it and everything worked as it should.

This could be or not be your issue,just wanted to give a heads up.

Ha, I just did everything ass backwards then. My fan just stopped working. I read up a bit here. I ordered a new heater control switch, installed it and nothing. It turned out to be my blower motor. I replaced it. Everything works. Sold my old heater control switch for a case of beer. I still havn't figured out to get that damned heat/noise shield on the BM back on. It came off, but I'll be damned if I can get it back on. LOL.

I think a good way to test beforehand, is to tap the blower motor housing, beneath the glovebox. I listened closely and could get the fan going for about 5 seconds, and it sounded like it was spinning off-kilter, like the bearings were shot. The switch seems to do its job, so I think I just need a new fan motor. Can't wait to have a proper flow of heat again, these freezing mornings are tough with just a trickle of heat coming through.
