My rear window defog seems to be cutting out in a much shorter time than normal..and won't restart for several minutes...Not a problem at this time of year...but in winter..well, that won't be so good. Anybody dealt with this before? Time for a new switch?

 

What year camaro? Sounds like a new switch is needed.

 

It's a 1998. As I said, it will come on initially, but will only stay on for about two minutes before shutting off, and won't restart until after a 7 minutes or so 'off' period.
