okay i have a pontiac bonneville sle 2001 and i have had the wheel bearings changed and the motor and trans mounts changed but im still getting vibrations while at a stop and a ,dry start also a moan when i accelerate, the other day i notice i had been at a stop for about 10 minutes and i hear a crackle or sizzle coming from behind the instrument panel and every once in a while i will turn the wipers on and the lights on my dash will shut off so i think i have a short ,,,,,but the question is can this also cause the problems i listed? thanks in advance!
