- Fuses.
- Test for 12 volts at the wires that connect to the window glass.
- Inspect the defrost stripes on the window glass for damage.

Mine did the same thing. On the back window in each corner at the bottom of the window there are 2 wires (one on each side). On mine, the passenger side wire broke free from the glass. All I had to do was close the door with myself in the back hatch area and re-solder the lead onto the window.

My rear defrost also doesn't work. I can see the wires in the hatch opening are broken. They need to be repaired. I don't have any play in the wires so I'll need to open up the headliner and the back hatch and replace some wiring.
