Rear Defroster draining my battery?
OK I'm having a little problem. Lastnight it was raining like hell here in L.A and my windows got fogged up. So I turned on my rear defroster and instantly my battery gauge dropped from 14 volts to just below 12 volts. Once I turned it off it went back to 14 volts is this normal or is this a problem?

doesn't take much current to activate the rear defrosters, i would imagine you have a short somewhere between here and there. I would pull the paneling on your hatch to see if it is collecting rain or something. Other than i would just check to make sure everything is snug... i'm having problems with my volts hopping around also but mainly related to rolling up/down the windows and kicking on the A/C.
