05 chev silverado fan wont turn off

Doing this for my husband so bare with me :)

He's got the truck turned right off and the fan is blowing still. He pulled out the fuse for the fan and it still won't shut off and now his battery is going to drain ( and I want to go quading tomorrow!) The fuse for the horn and seat warmers arn't working properly either or are dead.

What the deuce?

i have the same problem on my 2003 yukon, started with the rear heater/a/c fan wouldn't turn off, and was stuck on high. I pulled the fuse intil i had time to look at it. Now, 3 months later, the main heater/a/c fan is doing the same thing, stuck on high, and wont turn off, even with the key turned off. This yukon has the auto climate control

Replace the blower resistors/relay. It is one piece, they are made together.

It is the blower motor resistor. it is located under the dash in between the wiring and the blower motor. It is a little hard to remove the attaching screws.Because of the small space to work. But it can be done. It is a small gadget not a resistor as in TV resistor.

2004 chev silverado ext cab. No Power steering


Hi Hollings,

You description was very good, I need to ask for a specific.

When you turn to the left, the wheel is stiff like the engine is off or does it turn smoothly but the vehicle doesn't turn or seem to respond.

I'm trying to rule out broken mounts,

Also, if the wheel is all the way to the right, is it difficult turning back to the left the whole way, or half way. See where I'm going.?

Please comment back your findings

Best regards
Mike

05 chev 2500, blower motor 3rd speed was not working and now it only works on 5?


This is due to the fan switch or blower switch, the one in the dash not functioning properly. You need to replace this switch.
