Rear defrost/wiring problem
Hi Everyone,
I’m having a problem with my ’95 Bonneville and hope someone has an answer. The rear defrost button comes on by itself and kills the engine. When this happens I crawl under the dash and pull the fuse then the car would start back up. Well, lately this doesn’t seem to work. The other day I pulled the fuse and the light (on the r-def) wouldn’t go out for about 20 minutes, then the car started. The next day I was driving it and the RD light came on and the car died. The strange thing about this was I had the fuse pulled and the RD light still came on and once again I had to wait about 20 minutes till the car would start again.
What would cause the car to die when this comes on? Why would the RD light come on with the fuse pulled or come on by itself at all? I noticed the RD is connected to the hot/cold **** on the dash, could this be part of the problem?
Thanks for the help.

Sounds to me like either a short somewhere, or a failing alternator.
The short is for obvious reasons. The failing alt is based on my belief that the sudden draw is pulling more than the alt can handle and keep the engine running.
