So my rear defrost does not work. My parents tried changing the fuse and they said the fuse wasn't the reason why the rear defrost didn't work. So I was thinking, I'm looking in the manual and it doesn't say what fuse is suppose to be in the rear defrost place. Which is suppose to be there? I'm going to go through it tomorrow and see that there might be the wrong fuse in it's place.

Based on this, it's suppose to be 10, right?

I just went out there and there was a 30 where the RR Defog is. I put a 10 in there and it still is not working.

Just finished repair of a broken rear window defroster on a 2000 chevy cavalier. Unit would not heat rear window. I could hear the relay in the dash heater control unit click and the light under defrost button would turn on and back off after normal time out. I suspected a bad ground, but it turned out to be a burned connector/pins in +12v feed from control to rear. The connector is located under the the carpet along left hand side of drivers feet area. Just below the fuse box and BCM. There is a large (10-12ga) purple wire from dash control circuit going into the connector and a large black wire leaving. The black wire get bundled w/orange elec-tape and runs in the rocker panel along drivers side back to rear window grid connector on the drivers side. The passengers side grid connector is the ground connection. There are also some other smaller wires in the same connector (under carpet). The burned pin in the connector was so bad that I had to build a splice jumper (10ga crimped & soldered) around the bad pins. The other smaller wires and connector pins where fine so I just left them alone. Make sure your repair is strong, there is a lot of current in this circuit and hence the reason why the OEM version failed.
That doesn't' seem to simple.

It sounds more difficult than it is. Have you ever had your kick-panel/door-sill out? Once that is removed you just pull back the carpet around the "dead pedal". The connector is right under there. The wire for the defroster is the thick purple one. Pull the plug apart and look at the pin in the connector that corresponds with that wire. If it's melted then that's the problem.
