Not getting any power to master window switch. I have a used/new junction box under the dash. Fuse is good, relay is good, checked the continuity of all the wires to test for a break in one (even in door jam) and those all checked out good. Not sure what step to take next.

There is a P/wdw fusible link that we need to check. here is a window wiring diagrams below so you can see how the system works. I have included the link location as well and how to check it.

is the relay working? we are missing something because the relay powers the switch. here is the wiring diagrams so you can see how it works with a guide to help check for power:

I tested the relay the "correct" way and it tested good. I have power coming in slots 86 and 30 in the relay "housing" on fuse box. Nothing in slots 85 and 87. Is 87 supposed to show that I am getting ground when I use a test light?

I found the problem. I am getting a bad ground to the window relay. Could you tell me where that wire runs and what wire cluster it goes into?

You check for ground by connecting the test light to the positive side of the battery. It is the gray wire in the passengers side junction box. Let me know.

I checked for ground with a test light and volt meter. Wasn't getting anything out of it. I put a wire in the negative terminal in the relay and touched it to metal and it started working.

yep, it is grounded by the ETAC module (The Electronic Time and Alarm Control System module ). here is the location so you can check it out and replace it. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
