pulsating ac and instrument lights
Put the car in park and the AC along with the instrument lights started to pulsate tried revving up and kept pulsating, finally turned off truck for 30 min and has not happened again also now i have a high pitched noise which happens at random and can't locate the source. Has anyone experienced this?
