Just noticed last week that my 04 GP GTP climate control fan (AC/heat) drops in speed if I hit a large bump. Today when I came out and started the car, it was non functional so I hit the speed bump at the gym and it came back on. Any idea where I might begin my search for this short? ALSO, my internal power sources (cig lighters) haven't worked for a couple of year. Where is the likely problem there.
Thanks for help in advance.
