2006 Express blower problems
I've searched already and found all the threads about losing certain speeds or losing all but the top speed of the blower motor. My problem is the opposite of what everyone else encounters. I have speeds 1-3 that work great, and the top speed(4)is the only one that isn't working.
What should I be checking?
I figure it's not the resistor, as I have read that the resistor is basically bypassed in the top speed. Also, I don't believe it's the relay, as wouldn't the relay being bad effect all speeds?

You might have a faulty switch and also i would check and see if you have power at the Fan in high.. IF you do then your fan is shot.
However i would start at the fan and work your way back with it in high checking for power along the way.Mike

Some trucks have a relay for speeds 1,2,and 3 and a separate relay for speed 4. Good luck.1999 Silverado Regular Cab Short Box
