Answers :

Just go to your owners manual and it will tell you which fuse it is. Also, on the panel itself, it should say. If it is not the fuse, check the power at the defroster. There are 2 wires going to it. With a test light grounded to the frame or somewhere on the body, check both contacts while connected and the light should come on. If it doesn't on one side, the grid is burnt out. There is stuff you can buy to repair it at your local parts store with directions.
\015\012If they both DO NOT work, it is the relay in the dash.
\015\012 Unplug it and check that you have power goimg to it. If there is, and everything else is, buy a new relay.

Rear window will not go up. how do you replace the window motor? the switch on the main driver door does not work and the back rear passenger switch is not responsive either. I'm thinking the motor went bad. Don't think its the fuse, because the other window all work fine.
