Forgot to mention that I had already made friends with the junkyard and the other switch does the same thing. It will light up but wil not stay on. Is there a relay that may also go bad and if so where is it?
I donno. I'm almost ready to guess not judging by the amount of heat generated in the switch. When you say it lights up but doesn't stay on, do you mean the button doesn't physically stay down or the button stays down, the light stays on, but the defogger is not on?
If the button won't stay down on its own it's bad. If that's what's happening try a third one.
it will work if you hold the button down. mine does that too. not that big of a deal. there might be some sort of a clip behind it that would let it stay down but i havent bothered to tear my dash apart
I told you the switch is bad. There's a mechanical dohickey inside the switch with a spring that makes it so it alternates between held down and not held down. That dohickey is broken. It's very common. If you just got it at the wrecker then they'll give you another one.
Yeah it is definatley the switch, i have replaced them on both my escorts. I found that if you wedge something in the switch to make the light stay on your defrost will work but mine only worked like that for a while till it went completly bad. Just save yourself the trouble and go but a new switch, if you can get one.
