Whenever I start my truck it runs fine no problems. But if I use my PARKING BRAKE, put it into REVERSE, use TURN SIGNALS, or try to use my A/C or HEATER CONTROL PANEL, my volt meter jumps down to less than a quarter the way on. Its wierd cause my radio, lights and everything else works fine, just not those things listed. I checked my fuses and they are all good. Is there a short in my wiring system somewhere mabe?? If anyone can help or give me some ideas please do.
