Window motor only moves in 1 inch increments. Motor and switch tested good. Relay is prematurely opening. Where is relay?

Sounds like the window has lost initialization. Re-initializing the windows should resolve this. This is a common thing on your vehicle. How to do this move the window all the way closed once the window is closed from the window switch at that door with the door closed hold the window switch up for 17 seconds with the engine running.
