The info I looked at was for a two door. Yes, check the wiring harness, hinge side of door. Pull the rubber boot back to access wires. Brown wire, top, in diagram, is voltage to master switch, hot all the time, that key is on, voltage comes from power window circuit breaker. The black wire in diagram is ground. If you use a testlite between those two wires, key on, it should lite up. You have to penetrate the insulation. If good voltage and ground, have to check master switch.
