I've got a 2003 Silverado that the blower fan is acting up intermittently.
It will just stop turning occasionally, although I can still hear the relay between positions 4 and 5 click. It doesn't slow down gradually, it just stops. No excessive noise or anything. Then, at some later point, it's working fine again.
What should I check first?
Thanks.
Next time it stops. Leave it on and bang the fan housing with your hand. If it starts you may have a sticking brush or loose connection.

I called the local dealer today pricing a fan and he said that they've had a lot of problems with the fan resistor.

Don't know if this is common knowledge or not, but gmpartsdirect is WAY, WAY cheaper than any of the dealers nearby.
$60 vs $150 on the fan and $20 vs. $50 on the resistor
including shipping.
I'll try what you said. Thanks.
A sticking brush is still going to mean replacing the fan though, isn't it?
Yes, unless you can get it apart. About the resistor, if it's the problem, high speed will still work.

High speed does not. Thanks.
