It is for the W123133 (as noted on schematic) This covers several years up to 1985.

The only "133" that I see is the page number.

In any case, I have the 1982 Electrical Troubleshooting Manual; it's not the the same as your schematic. My terminal numbers might not be correct for an '84.

I admit is not clear just what that 133 means. I see in the later ETM that the power windows schematics are on pages 132 and 133, so you could be right.

Regardless, it seems I do have the later schematic too. If the switches have internal LED backlighting, then this schematic should be correct (it is for my 85)

It's the page number. No doubt about it.

I admitted that you could be right, but you just don't give up do you?

OK, so does that make your terminal numbers correct - to test my ground?

Set your meter to Resistance. Then with switch plug disconnected, connect meter leads between pin socket 4 on the switch plug and a good ground. If I recall correctly, there is a ground connection driver side near shift lever (but any chassis ground will do). If the ground is good, meter will read 0.00. If it is not connected to ground, it will read Infinite (very high) resistance.

You might try applying 12v from external source to pin sockets 1 and 2 and see if motor runs. If it does and ground was good, then get a new switch.

If it does not run, another check would be to disconnect green and black wires inside door. Then measure resistance from pin socket 1 to green wire inside door and from pin socket 2 to black wire inside door. They should read 0.00 if the wires are not broken between door and switch plug.

Good luck with it.

If in doubt, brown wires are always ground.
