Where is this located?Under the hood? Inside? Can you help direct as to where this is? Also do you agree thisis the problem?

Expert:  BigBob replied 6 years ago.
Sorry, Under the hood, you will need to pull the cover to access it usually. This is actually on the firewall.

Hi,

 

OK....you are a real expert and I'm just a wanna be. You need to help me some more. You say "you will need to pull the cover" What cover and how do you remove it? If we disconnect the module can we run the car? Is the the AC blower also?

Expert:  BigBob replied 6 years ago.
This is the same blower for the ac. There is a black plastic piece that runs along the firewall that has to be removed. Remove the plastic shield and unplug the wires from the
blower motor and it will stop. You can drive it unplugged but there will not be any blower. You can also pull the blower fuse, fuse 3 in the underhood fuse box. This picture may not be exact but follow the wires from the blower motor.

I forgot to mention, that if you replace the module I would replace the blower motor also because what usually happens is the blower motor pulls too much amperage the module gets burnt out.
