Thanks for the quick response Benzmac. I finally had a chance to check into it some more. The fuses are ok, an I get 12 volts+ at the bottom right terminal where the switch itself plugs in. Looks like the power to the switches is ok. The lower center and lower left terminals are ground. I don't know what the two terminals on the top are for. Anybody have any ideas? Are there any other switches between the switch and the window?
