Chev. Silverado 04, Air Conditioning Fan Switch?

Anyone know anything about the Fan Speed Switches on a 2004 Silverado?

When the truck was new, 5 on the Fan Speed went out, then it quit completely. Took it to the dealer and they fixed it. Not replaced, but fixed.

They said there was alot of trouble with these switches or relays or something.

Anyways, 5 %26amp; 4 quit working now. I've heard several people talk about he same problem.



Anyone know what parts to buy or how to change the switch out. Don't want to take to dealership and pay mass amounts of money for the fix if I can avoid it.Chev. Silverado 04, Air Conditioning Fan Switch?
the fan speeds are controlled by a series of electrical resistors. when you turn the switch it connects a couple of these resistors together to determine the speed.

they are a pain to get to because they are usually under the dash and inside of something else you have to take off.

With labor at 90 and better per hour it gets costly.

If you are somewhat handy get a manual and do it yourself.

the manual is 25 the part is less than 20 you do the math.
