    At this point in time you might also want to think about what overloaded the resistor.

    If the blower hasn't been changed this would be a good time to change it. Also wash out the AC coil and heater core while your there.

    The wiring feeding the blower motor is a little on the light duty side.

    Add a ground from the blower to the dash pivot bolt while you're at it.

    There is a plug there feeding the blower motor. The wires here frequently have the coating heat damaged & unless it has been replaced they will eventually fail.

    I use a 1/4" Craftsman cordless ratchet for a lot of the hard to reach spots.

    The other tool I use is a little ratchet that accepts 1/4" hex bits. I got it out of the bargain bin at Napa for $4. I know that stuffs made in China but I've never seen those anywhere else.

    I believe the screw heads are 7 or 8mm.

    My 1996 Suburban k1500 blower motor works great on speeds 1,2 and 4. I replaced the console climate control switch assembly because the speed control switch was becoming intermittent. Speed three would still not work, so I replaced the resistor pack and noticed that one of the resistor coils looked overheated - blue. Hooked it all back up and still not speed three. I did not notice any burned wires and the connectors were not melted or burned looking. My Suburban has 255,000 miles on it, so I know it is going to have weird issues. Any ideas on what might be wrong?

    This was a huge help! I stumbled across this in a google search. Looking for an easier way to get this done than what both the Haynes and Chilton books said. I wasn't wanting to tear the whole dash out to replace the resistor.

    Im glad that this was a great help to all. I have since sold "Big Bubb" but I hope that this will continue to help all that come in search of knowledge and help. Until I buy my next one, keep it real fella's.
