Rear window Defogger Telay

[Mach I Pony]

Will someone please tell me the location of the rear window / rear light defogger/ relay?

I'm not sure there is a relay per se, but rather a switch which feeds off of a secondary power line that has a circuit breaker at the starter solenoid.

On my '71 it is passenger side, behind the glove box.

Yes it is above the glove box on a metal plate. Remove the liner and you will see it attached at the top of the glove box opening. It is hard to access kind of. If you feel comfortable removing your dash pad it’s better to access it that way.

The relay plate above the glove box drops down with a couple screws.

I tried to get to mine that way and it didn’t want to drop down much. I was able to get to what I was after but it was a pain in the buttock. Do A/C cars have more duct work?
