Just bought a 1983 300DT, the front pass side and the rear driver side windows do not work. Would it be a relay and if so, where is it located?

to check if its the switches, pull the two switch assemblys, plug the non working window's plugs into the slots for the windows that work, and see if they work. if they do, uv got a bad switch.

Does the rear not work only when using the console switch or does the door switch not move it either? If so, it's probably not the switches, since it's unlikely that both of them would be out. The 123s did not use window relays. Check the fuses if you haven't already. To be safe though, take out the driver's side combo switch and swap it with the pass side one, see if that does anything. If you feel really adventurous swap the door ones, too. If none of this helps, the switches are not the problem, you probably have two bad motors.

It's one of the fuses. Can't remember which, but there should be a thick piece of paper behind the fusebox cover indicating which fuse it is. If it's easily seen you can easily determine though. The fuses control an X pattern for the windows, hence your case.
