I am having a problem with my 04 Grand Prix blower motor staying on with the key off. Im not understanding what you mean by the blower control module connector. Is this under the dash? Or are you talkin about the fuse box? Also what does this capacitor look like? My pink fuse looks fine.

assuming you know where your blower motor is you can check the motor for power with the switch on and see if you have battery voltage at the connector. if you do then it is a bad blower motor. Most of the time when a resistor goes out it will work on high only but no other settings. with it not working at all seems to be motor. Hope this is helpful.

My 04 Grand Prix was doing the same thing. Not sure if what I found was the reason for it, but I removed the air filter portion of the intake, reached into the intake a little pulling the throttle plate down. It was caked in carbon build up. With a lint free rag and some throttle body cleaner, I scrubbed the plate and since have not had anymore issues with the car not starting. Hope this helps anyone.

I have an '04 with approx. 79000 miles; the blower is going out on mine too. The motor is probably burned out and you will need to replace it. It's about $90 for the part. Kind of a pain to change; I changed the blower motor on my 97 'prix and I had to lay upside down on the passenger seat and work on it upside down. Other than a little physically uncomforable, not too hard to do.

SOURCE: what tool do you use to get the blower motor

the bolts are 9/32s

SOURCE: i changed the blower motor and resistor on my 2005

doesnt work on all speeds? ck the big purple wire at the blower motor, on high speed, it should have battery voltage, if it does, then check the black wire, it should have "0" volts (or ground it, see if it then works). If the purple wire does not have power then fuse #30 (30 amp) may be bad.If the black wire has more than "0" volts then the ground may be bad or the "blower motor control processor" =( resistor) is bad, or the ground for it is bad. the ground wire ends up at the cross beam behind radio. If you ground the black wire at the resistor, and it works, then you have a bad ground at the wire, behind the radio. Good Luck.
