Replacing the Rear Window Defroster Switch on your Ford Escort? The Airtex 1S is a genuine replacement, with the fit of an Original Equipment part .
Picked up a 96 LX, the rear window defrost/defogger switch will not stay I even grabbed a switch off an Escort in the recycle yard, and it does.
I dont think a relay is involved anywhere for the rear window defroster, or the OEM switch might have held up longer. At least no relay is shown.
