Need Some help with my window defroster hello I don't know if this is were this would go but I think it is. Anyway I live in michigan and it has been raining and geting cold here and I whent to use my front window defroster today and it didn't come on there is no air blowing out of the vents. it is the same when I try to use any seting heat, ac, vent. So my ? is what is going on. Also the other week when I was driving at night the little lite in the rear defroster switch whent out don't know if that is important or not. |
The front controls are vacuum powered I believe. Look under the hood for a vacuum line that is unhooked or broken. Hard to see sometimes look close. Rear defog has a timer in the switch, goes out after a couple minutes. Think this runs on a circuit breaker in the fuse box under the dash, no fuse on it. (edit, your 91 Firebird may have electric heat duct controls, not sure. Sorry if I'm wrong) |
It may be the ground wire for your blower motor. That was my problem |
k thx I will take a look at those things |
