The #'s were Battery w/out the car running gave out 12.56 with the car at idle and warm it registered 14.27. What is the OVP fuse and where is it? and the reason I warm it up is it's better than driving down the street with my head out the window while I wait for the window to de-fog.

One other thing I forgot to mention is when I tried to put on the rear defogger the light just blinks and it wouldn't go on.

Thanks
