Default Rear Defogger Dosen't Work

I have a 1982 corvette. The rear defogger switch on the console plate lights up but my rear defogger in the glass hatch does not work at all. Any suggestions or comments would be appreciated. Thanks

Inspect the filaments that line the rear window. Breaks in those filaments will cause it not to work. I believe they can be repaired, but that's where I would start first.

check the timer for the defroster. If Im not mistaken there is a relay/timer in line with the switch and defroster elements. Also check the wire connections at the rear window and make sure the contacts are not coroded or rusty.
