I had to get on the brakes fairly hard on the highway last week.It caused my sat radio to shut off,it was plugged into the 12v port.Now when I turn on the AC or the heat the signal lights and the highbeam indicator come on and stay on and signals will not work.This also happens at night when I turn on the headlights.If I turn on the AC/heat the signal and highbeam lights get brighter when headlights are on.Also I cant get it out of park with the lights on.During the day without lights and AC/heat on the signals and 12v port work fine...I checked fuses,relays and Alt seems to be working fine. anyone have a clue??
