I had my heater on for about 5 minutes tonight. I looked down at my battery gauge and saw that it was almost in the red. I immediately shut the heater off, and sure enough, went right back up to 14 in the middle.
It has done the same with AC, although AC generally blows a fuse, so I've got my fan clutch switch unplugged. Heater/AC works but doesn't blow cold air. I had assumed that I was only getting the voltage drop with AC, I had a bad fuse that didn't blow when it should, which is why the AC turned on in the first place. Now tonight I see that the heater is pulling too much voltage.
Anythings I can check for to see if it's something simple? It's going into the shop Thursday to have the AC worked on and recharged w/ Duracool. I'd like my bill to be as little as possible, and I know hunting down electrical problems isn't going to help keep it low.
Thanks
