... your initial description was the proper behavior based on the experi-
ence of my car. My observations on the '88 5kCSTQW is that when the igni-
tion switch is on, the window/sunroof switches are illuminated. After the
ignition is switched off the switches remain illuminated for a short period.
If a switch is actuated all the switches are again illuminated for a few
seconds. As soon as either front door is opened the circuit is deactivated.
I suspect that from your description you will be able to roll the windows
up and down as long as you see the switches illuminated. I was thinking
that the problem was due to a malfunction of the door switch, but if this
were the case the illumination would switch off eventually. You're problem
may be that the ignition on signal to the window/sunroof power controller
is always on or the power controller itself has failed. The wiring diagram
in the Bentley manual should give you the info you need.
I don't know if you regularly open the passenger's side door, but if not
it may be worth a try ...
