Why is my car having weird electrical issues

First, have you checked the condition and state of charge of the battery? If the battery is too low in charge or unable to provide sufficient power to the vehicle, it can cause odd things to happen electrically. Other than that, hands on testing must be performed with special attention paid to any abnormalities over the 29 year life of this vehicle. Accidents? Water damage? Windshield replacements? Corrosion? Always look for the unusual things that have happened and how it influences the way the vehicle is now. www.repairpal.com/repair-shops
