Why are my window switches staying on?

[Roa, Greg]

Hello all,
Got home late yesterday, and noticed a problem when I turned off the
car.  Was driving the 86' 4kcsq, and when I shut off the ignition, and
took out the key, the lights on the window switches remained on, as well
as the lights on the sunroof switch.
It didn't keep power to the switches to actually move the window
regulators, but if I tried the switches, the lights went out while I had
the switch depressed, but came right back on when I let go.  Also, if I
activated the blower fan switch, or the rear defrost switch, the lights
would go out until the switches were back in the off position.
I then tried restarting the car, and wiggling the key around in the
switch, but nothing I did made any difference.  Got out of the car,
locked the doors and they still stayed on.  Drove the car to work this
morning, and they stayed on again after I got there.
They're not on at full brightness, but they show up fairly well at
night.

Anyone have any suggestions?

Thanks!
