Master Switch Inoperative, Individual Switches Are Operative
- Disconnect master window switch 10-pin connector C1. Turn ignition switch to RUN position. Using a test light connected to ground, backprobe master switch connector terminal "F" (Brown wire). If test light is on, go to next step. If test light is off, repair open in circuit No. 141 (Brown wire) between master switch and power window 30-amp circuit breaker.
- Reconnect master window switch connector. Leave ignition switch in RUN position. Using test light, backprobe between master switch connector C1 terminals "B" (Tan wire) and "A" (Light Blue wire). Press right front window switch at master switch to UP and DOWN position. If test light does not illuminate in both positions, check for poor connection at master switch connector. Repair as necessary. If connection is okay, replace master switch.
