Howdy All,
I have a 2001, 379, the blower motor/fan switch will only work when on the HIGH, number 4 position and then it only barely moves any air. I am "ASSUMING" the resister is bad but have no idea of where to look for it. Again, I am "ASSUMING" the blower motor can be accessed behind the large plastic cover under the dash on the passenger side but really don't know where it's located or how to get to it, I think the blower fan is loose as it rattles when it spins.
Any help you can give in me being able to find and replace these parts will be greatly appreciated, THANKS.
Dave

Lower cover in front of passenger seat needs to be removed.
Glove box needs to come out also.
You will see the motor unplug wires
Pull out rubber that feeds cold air to motor.
4 bolts hold blower motor in air box.
Save yourself the aggravation and buy the motor and cage as one unit.
Them wheels are hard to get off and if you bend it it will sing to you.Mr. Cob, blairandgretchen, Coolbreezin and 1 other person Thank this. -
Everything FLHT said sounds correct. I didn't have to remove the lower panel though. I have a 91 and mine is directly behind the glove box. The fan switch is on top. While you're in there, consider cleaning fan blades and heater core fins also.
Mr. Cob Thanks this. -
Ditto @FLHT.
Mines 1995 - about 8 screws holding the glove box in place then it's all there.
The little panel with one screw at the passengers foot has your condenser behind it with the cabin air filter.
I use CAB MATE - it's a plastic case with charcoal filters that you replace, I keep mine changed out pretty regular after having to replace the condenser that was totally plugged with crud from the previous owner.Mr. Cob Thanks this. -

Thanks for the good advise to check and clean things whilst I am in there.

As I just replaced the condenser last year, I'll be sure to check out this "CAB MATE" thing. Thanks for your reply.
Daveblairandgretchen Thanks this. -
Thanks for your reply, I don't have to ask, I too have experienced slashed fingers from them being someplace they shouldn't have been when the switch was thrown. Dialectic grease is one of my best friends NOTHING electrical goes together without it being used.
