I have a 1990 Silverado that the passenger window quit working, thankfully it was in the up position. I changed out the motor/regulator with a new one and it still will not work. The window on the drivers side still works however.

Do I need to just trace the wires or is there a problem wire splice to look for? I appreciate any advice on this issue.

run a wire from your battery straight to your window motor. if it works, then you need to replace your switch or trace where the problem is in between.
