Just installed my new window switches which FastLane shipped so quickly. Turns out there must be another problem. As I understand it, the right front and left rear windows are on the same circuit, I checked (replaced) the fuse but the windows still stay put. Any ideas on what to check next? The left front and right rear work fine.

Thanks!

If both are down, I'd say you have a power problem that derives from the fuse area.

I would look again at the fuses. Replace all that say windows. You will want to check top and bottom of the fuse connector for proper contact.

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?
Thanks!

Well, I worked on it some more this afternoon. The right front ended up being a very unusual problem. There was power to the switches, so I decided to check the door motor. The black and green wires from the switch meet a set of black and green wires from the motor at a small junction block that clips to the door under the door panel. Once I until the screws, cleaned some waxy looking stuff off the lugs and put it all back together, it works great. I'll check the left rear later, but I suspect it's the same problem.
