Hi, I am not too engine savvy, however I was working on my older 97 grand am 4 door 6cy. I was assembling the interior door and listening to the radio and i think i shorted something out (possible the window motor)..anyways the car will not crank now, would crank flawlessly before this happened...I am most certain its not the battery, and I have checked every fuse in and out of the engine (except the grey/metal fuses)....and IM not sure what to check next, any help would be grateful..possibly the starter or solenoid switch? or maybe something more simple....thanks
