I would replace the blower motor resistor. It varies the power to the fan, for different fan speeds.

1997 Pontiac Grand Prix GT; Elec problem with fan

Replace the blower resistor that is mounted next to the blower motor on the passenger side of the vehicle.
This will restore correct blower operation and I suspect it is also back-feeding voltage resulting in your electrical issues.
Two screws hold the blower resistor into the heater case and it is very easy to replace.
Good luck

2000 grand prix fan speed

i have been having that same exact problem with my 2002 grand prix for over a year now, and when my ac is on the lower setting the it doesnt work plus the headlights and lights on my dash go out. On Max everything works. i changed the blower resistor(about $35), still doesnt work. i changed all relays and fuses related to the ac, still doesnt work. i changed out the actual ac control switch in the dash, still doesnt work. i have changed everything but the blower motor and have asked every mechanic and auto parts retailer i come across and no one knows the answer. The best answer i got is that it is probably a wiring problem like a short somewhere.

Heater fan will not shut off runs all the time on high speed. 03 dodge grand caravan

Sounds like resistor is faulty. I believe on that vehicle, look up under dash behind glove box, and you should see blower & the harness that runs from it to a resistor attached to housing/duct. Pull connector off to stop blower. Replace resistor.
