[V8] Rear Defrost Switch

[Ron Wainwright]

You should check power @ the switch when the light isn't on as well, just to rule out that being the problem. Cause in my 20vt the Def "triangle" sometimes lights up & sometimes it doesn't.... but my rear Def works with the switch liteup or not.

 Then work your way to the rear window wires for the def.
 & not sure... W/O looking @ the manual... but the ground wire MIGHT go through the trunk hing. I'de check were the ground is as well.
