I just bought a used G20 that is in relatively good shape. When I try to start the car sometimes I won't get anything but a click. No dash lights, wipers, clock or anything works. Then sometimes it will start right up but I still won't get any dash lights or wipers or anything until I rev the engine then everything is lights up and is fine until I have to start the engine again. The clock resets to 1 o'clock so I assume that as soon as I cut off the car no power is getting to the dash at all. Also, when it is running if I try to turn on the heat or air the dash goes dead and the engine idle drops and will cut off unless I keep the throttle depressed a little. I'm not sure where to even start with this one. I have had suggestions from the battery to the alternator to relay issues. The only thing I have checked is the battery. Please help!


Thanks in advance,

Kobey
