I have a '94 4Runner SR5 V6 Automatic. I have a brake light that's out, and I figure that I have to lower the tail gate window (by switch on the center console). The gate window doesn't work, I opened up the panel, and there is what looks like calcium build up. Does any one know what could be wrong, and fix it? I have a maual for it, but it doesn't mention anything about the window. Dont want to take it to a dealer ship.
