My headlights have started acting up. The drivers side headlight will dim and both high beams will come on dim but the passenger low beam is normal. Also when that happens my air conditioner compressor kicks off. I can switch the lights off and the a/c compressor will kick back on. I pulled the ground wire behind the front bumper off and buffed off the metal and the connectors and re installed it and it didnt change anything. Any help is appreciated.
