Another problem now that it is cold and snowing here in Indiana. My rear window defroster doesn't work. The rear defrost light does not turn on at all. I looked at the fuse and it looked fine. The first time I tried to use it a couple weeks ago it did not work. I went back to the connectors on the rear window and wiggled them around and the next time I started the car the light came on and I turned it off because I was just testing to see if it worked. Then a week later I tried to usethe defrost again and it didn't work. I didn't have time to fuss with it so I left it alone. Now that is snowing and getting iced over a lot, I would like to try to fix it. I tried playing with the wires again and I can't get it to work. I was thinking it could be the switch but I don't know how to test it.
