: Rear defrost problem

09-20-07, 07:59 PM
Hey guys, this morning i was driving to work and turned on my rear defrosters and noticed that the top 6 inches or so of the back window dont defrost. Lets say theres 18 of those coils or whatever, the top 6 of them dont work. Are they supposed to work? also im noticing alot of rattling going on on both driver side and passenger side doors when there is bass. Is this common? thanks

I can tell you that the rattling is caused by something loose in the door. Your dealer will have to take the door panel off to fix it. I can't remember exactly what is was on mine. Just that is wasn't a blown speaker as I once suspected.
And, yes, the top 6 coil thingies should work.

Depending on what Caddy you have, the top grid lines in the rear window may be your radio antenna. On my Deville, the top 4 lines are actually the radio antenna, but you can still see fairly well without having the top 6" or so of the window defrosting.
