I have an 87 na with a rear window defogger not working. I am reading different stories on different sites on what could be wrong so I thought I would check here. Here is what I know.

I am getting 12 volts from both left and right side wires.
The grid is good.
Both shocks are identical and in good shape, they don't need replaced. I do not believe they are OEM.
My right side heated mirror works but not the left.
I am having issues with the interior lights not shutting off, just going dim with all doors shut.
I have not blown any fuses.

I have a couple ideas but I know someone knows exactly what I should do. Thanks. gnccquadracer@hotmail.com

The struts shouldn't be the same.

I have the exact same problem...did you get yours resolved???

The right side strut should have a guard and switch on it at the lower end... this is what triggers the rear hatch area light when the hatch is opened..

The left side strut is the + connection for the rear defroster, the right side strut is the ground for the defroster and the switch... teh wire at the right strut is for the rear area light, and has nothing to do with the defroster (unless you have 2 left struts fitted, in this case you have NO ground path for your defrost or light)..

The flag mirrors being heated... you may not have a heated mirror installed, it would need to be removed to be checked.. to do this there is a locking ring holding the mirror on, it is dis-engauged by inserting a screwdriver in the hole in teh bottom of the mirror bezel (look and you will see it) and using the screwdriver to unlock the ring... I have a broken mirror at home I can take pictures of if you need a picture!

+1 on John's.

They are different.

I would (as I always say), clean all your grounds. There's two main ones back there. The mirrors are a pain to pop open, lol!
