The fuse Steve refers to is in a separate black housing about 2" long by 1" wide. Removing the cover will show a strip fuse with a screw in each end to hold it in place. I've blown mine and to make it work until I bought a new one, I soldered it together to have AC. With this temp. fix it can still blow but next to where it is soldered. Buy a fuse along with a spare to keep in your car.
