Fox Body Electrical Gurus, Hi!
I'd appreciate your suggestions with my hatch window defrost problem described below.
CAR: '87 hatchback
Problem: Turning on the rear defrost button does not even make the slightest difference in any fog or glazing of ice on the rear window.
Volts: 12+v measured at the two tabs that are mounted to the glass (The fine wire grid is fed from these tabs)
Volts: 12v measured on each of the fine wires in the grid in the main backlight (glass)
Amps: 55-77ma measured from each grid wire to ground
Grid Wires: I've visually inspected the fine grid wires and they do not seem to have any breaks along their length.
Tint: There was "temporary" tint on the glass. I label it temporary b/c it was NOT held on by any adhesive. It was held up perhaps by static electricity or something. I had bought the tint solely because it did not have adhesive. The tint was on for a few years. I easily peeled it off last autumn by just getting my fingernail under one corner. It came right off. The DEFOGGER was indeed effective on fog & ice glazing with the tint present. But last winter, after the tint was removed, there was no noticeable defogging or de-icing.
I had read through the following on a 94/95 but it didn't lead me to discover anything on mine.
