My blower motor was making a loud noise. It had a rapid bird chirping sound at any speed. Very annoying. I decided the motor needed replacement. I may have been wrong! Before you decide on replacing the motor see if you have a port in the bottom of the motor you can spray lubricant into. I didn't discover this until I removed the motor. I think some white lithum grease may have done the trick. If you think your blower motor is repairable, and it probably is, read Randy Mullins article How To Fix Your Squeaking/Screeching GM Blower Motor detailing repair of his blower motor.
My blower was original and now over 8 years old and I managed to get it out, I figured I should replace it. So on to the replacement!
Replacing the blower
First the tools
- Socket wrenches
- Pair of pliers
- New blower motor
I bought my blower at Autozone in Ypsilanti, MI. Their price was better than Murray's Discount Auto Parts in Ann Arbor. This blower seems to be used on a bunch of GM cars.
Here is the footwell with the kick panel in place. The 3 buttons are push-in clips. Mine were a bear to get out. I levered them out with needle nose pilers and a screwdriver. I mangled them quite a bit, but could still use them.
The kick panel open.
Just twist the bulb holder to remove.
Here is the blower exposed. Get ready to move the thick wiring harness.
The harness is held in by this clip. It was really tough to compress the clip and slip it through. I used needle nose pliers to pinch it. You might want to grab a mirror so you can see it. I couldn't fit my big head deep enough into the footwell to see it.
Here I've removed the 3 bolts holding the blower. You can't pull it out all of the way, yet. You have to disconnect the power lead first.
