Windows and Sunroof don't work? 100/200/5000 Models.
The accordion boot in the drivers door jamb holds the secret.
If the switch in the drivers door arm rest doesn't light up, its most likely not getting power.
Apparently, the LARGE wire is a GROUND for the windows and sunroof.
Now this large wire can be intact and still not have the
passenger window work of the back seats either...
There are smaller gauge wires that daisy chain (like old fashioned Christmas lights)
power to the passenger and the rears.
If these smaller wires break up stream, the downstream (pass & back) windows won't work.
