I have a '99 Grand Prix GT and recently my blower stopped working, which is apparently a common problem, but it also shuts off my headlights whenever I turn on the fan. Fan setting 5 used to work sporadically but now it doesn't work at all along with 1-4. The headlights go off if they're set in automatic or manual.
Also, my rear window defroster doesn't work anymore regardless of fan setting; though sometimes the light flickers once when I push it. The AC won't turn on either. And occasionally both of the power windows won't work on the right side of the car.
I'm guessing I already need a new blower motor and/or resistor, but what about the other electrical issues? There seems to be a short occurring somewhere but I haven't the slightest clue where to start looking. Any ideas?
