Blower motor remains on.

Hey all, Just signed up to try to find out why the blower motor remains on In my Tahoe when it is turned off and the engine is off with the key out? I have to pull the fuse to stop it. 2005 tahoe. Thanks

I believe its gonna be the blower relay. I've read about the same symptoms on the web somewhere. I'll try to find the link.

Thanks Donut. I just had the condenser replaced and I belive the blower this summer at the dealer and my rear end stil hurts. Do you think this would fall under the one year service garanty? I read the link and to be honest I'm abit stand off'ish when it comes to working on cars. My snowmobiles, duck boat motor, and our I/O no problem. go figure? I just get nervous when it coms to our car's. Because we need them running more than our toys.

Thanks for the advice.

Todd.

I think its a easy fix, but from what I remember, there have been several different designs and you need to look at the old one to match up the new one. Either that or the a/c actuator, I cant remember which. Its hell getting old.

Holy poop!! pulled the blower motor resistor. put the fuse back in with the key out of the engnition, and the motor ran. So I figured n/p I'll just hit the auto part store and I'm done. $350 for a dam resistor!!! the guy told me it's because I have the automatic temp control. On a good note he said it could be a short, and if it is when the part comes in plug it in and if it still runs with the key out he will take the part back and refund the money. So I guess I got that going for me, but it just leads to another issue. If GM had a face I would punch it right now.

Wow, I just looked up a blower motor resistor on rockauto and found it for $95. http://www.rockauto.com/catalog/raframecatalog.php

I cant find the part on rockauto. Was it an automatic temp contro resistor?

 

[todd273]

Ok I think this is the part. I wish I could see mor pics of it though. Is there a way to cross reference the part numbers?

This is the part number on the rockauto site.1580568

Found a better deal. called the auto parts store and getting a refund as I orderd the part and it's not in yet. here is the one I found for $101.04 with shipping.

no prob.

Put the new resistor in and still had the same issue????? So now what?? I'm guessing it's the the switch or a short. I'm clueless. I cant even go through the selections ig, defrost, dash feet. Think I need to take it to the heating and cooling shop. Gonna get cold hear in MI and I have a duck hunting trip up noth next weekend!!!!! Got to get it fixed. On a bright note, I can return the part.
