Electrical problems
While driving suddenly trunk opened, windshield wipers stopped working, door locks went up and down, lights on and off. Beeping constantly. Was not able to continue and had to drive back home. Was told by friends and others that there was a bad ground and to fix it will be very expensive as $500.00 +
Looking for solutions, suggestions what else might be wrong with, what mechanic should look for and where exactly etc etc. please respond.
