Switch Voltage Test

Performing switch voltage test determines if voltage is available at wiring harness. Remove control switch from trim panel. Carefully separate terminal block from switch body. Using test light, connect test light lead to Black or Gray wire terminal. Turn ignition on and touch other test light lead to Tan wire terminal. If test light glows, wiring harness and circuit breaker are okay. If test light does NOT glow, inspect wiring harness and circuit breaker. Perform SWITCH FUNCTIONAL TEST  to determine if window switch is defective.
