Lets get started on this fan repair. First of all you need to be able to bend like Houdini! Why? Because if you do not have a flexible body, you will not be able to make the repair.
First step in this repair is move the front passenger seat back as far as it will go on the track. Up underneath the dash, just behind the glove box is a panel.
There are three snap plugs holding this panel in place. Remove the snap plugs and pull the panel out of the way. This procedure might require that you remove the glove box on some vehicles.
Once the panel has been removed you will have access to the fan unit. Remove the fan assembly by removing the three nuts holding it in place. Now comes the miraculous fix!
Behind the fan unit is the fuse module that they were talking about in the repair guide. The fuse modules are the same on all Gm vehicles. Remove the small screws holding the module in place.
Now pull out the fuse module and disconnect it from the wiring harness. The replacement for my vehicle was $25.00 brand new from Autozone. The fan unit itself cost $98 dollars.
The fan unit is hardly ever the problem. But you do need to clean the fan blades off before you replace the unit. You can test the fan using some alligator clips you can buy from RadioShack.
Connect the +lead+ from the battery to the red wire on the fan motor. Connect the -lead- from the battery to the black wire on the fan motor.
The fan will turn at full speed! Connect wires long enough to make sure the fan works. Now you know which component is at fault. So most likely you will be replacing the fuse module.
That's all there is to it, you went through the procedure found the problem. Look online and find your replacement module and install it. This repair was very simple!
Now, plug new module into wiring harness. Put screws back in module. Plug in fan unit and put back in place and bolt back down with retaining nuts.
Replace the kick panel and snap plugs. If needed you can get new snap plugs at the auto supply store where you purchase the fuse module. Now replace the glove box and the job is complete.
You just saved yourself a few hundred dollars in repairs.
