My rear defogger don't work what could the probelm be?
Hello FOX-- The two problems you are having with your 1997 Chevrolet Cavalier are probably electrical and probablyrelated. Without a hands-on diagnosis, I would say you have a problem that should be looked at by a professional. Electrical problems are hard to handle for the amateur mechanic, but a competent pro should be able to pinpoint the problem. Good luck from Bovan.
