New to me 80. Seems like the rear defrost is not working. Either that or it works very slowly. Fuse is good. Switch Lights up. I do have power to the connector on the drivers side or the rear window, none on the passenger. I assume drivers side is hot, passenger ground? Any idea what to check next?
 
I had to gently reflow the solder where the connector attaches to the element in the glass as that connection was broken. You can check if the elements in the glass are getting voltage with a multimeter and small piece of aluminum foil across the glass over the embedded elements.

There are repair kits out there for the elements. Also endless youtube videos detailing how to test and repair them.

Also get your FSM at the link in my signature, it has the electrical wiring diagram (EWD) that shows this circuit.
