Thank you El Dusty! MAN, that tip saved me a trip to the dealer. It only took me 2 weeks of ignoring the problem before I checked on the forum!

Spent some time searching with no luck to my problem. This old thread comes closest

Rear defrost isn't working.
Wiper works just fine.
The LED indicator lights up.
30amp Fuse under hood is good.

My suspicion is when the body shop did some work on the hatch, they didn't connect up the defroster??

Where would I start?

Could well be a broken run on the glass. They are easy to break if care isn't taken with them.

A careful visual inspection will often reveal a broken "wire", or run on the glass. It only takes a very small gap to stop the entire grid to stop working.

Aldo, check the cable going to the rear door. It can have wire(s) worn through, which could be causing the failure.

See the attached pictures for the FSM pages for "how-to" check the rear window defogger system.
