I was under the dash all freaking afternoon... and still, no beans.
So basically my 04 GT2 has the same issue as any other GP - the stupid windshield cowl piece let water in, and I never put two and two together until I read more about this issue online. Now I know, it's just a $3 piece of plastic you can get from your local GM dealership's parts counter. Let me know if anyone needs the exact part number, I'll look it up for you.
Anyway, driving down the highway one day I'm like "what's that nasty burnt plastic/electrical smell!?" turns out smoke is billowing out of the vents and then finally stopped 5 minutes later. After concluding my car wasn't actually on fire, and once I got back home, I pulled the blower motor, and ordered the new one online from rockauto. Today I replaced everything, even a new cabin air filter from the local NAPA (to get rid of the nasty smoke smell), febreezed the whole damn car, and even installed the new part that GM released in a TSB service bulletin to properly drain the rain water away from the airbox.
So everything's back together... my fuses look fine. What else could it be? Does anyone know how I can check the resistor? Mine has obviously already been replaced or messed with when the previous owner had the car, because it didn't have the rivets. these were cracked off, and the other two screw holes were being used with screws in them.
Has this ever happened to anybody else?
