How to Replace a 2005 Bonneville GXP blower motor
ZeeVert – R Veldman 9/24/2008
At the time of this write-up, replacement motors cost at least $130.
The blower fan is relatively easy to get to and remove.
There are 5 screws and a few wire connectors.
With a few tools, you can have it out in about 15-20 minutes.
This car is a GXP. Your Bonneville or other GM may be similar.
My recommended tools:
Small screwdriver (for connector)
5.5mm socket (or 7/32”)
7.0mm socket (or 9/32”?)
There is a plastic kick panel under the glove box.
Using the 7mm socket, remove the two black screws.
Pull the panel back and down and the Christmas tree retainer will also pop out with the panel.
There are up to two wires connected to the panel,
The small black connector appears to be a temp sensor(?). I used the small screwdriver to help disconnect it.
The larger, blue connector is an interior lamp. Disconnect it with finger.
Set the panel aside.
The motor is located against the firewall, towards the front of the car. If you’re seated in the passenger seat, it’* just above your left toe.
Unplug the 3 wire connector from the motor with finger.
(There are 4 Philips screws in the motor. Don’t bother removing them. It’* just a cover.)
Using the 5.5mm socket, remove the 3 gold screws.
The motor will drop out.
Wiggle and twist the vent hose to remove it from the motor.
Done! (reverse order to install)
Well, I hope that wasn't too much.
