Perform BODY VERIFICATION TEST  under VERIFICATION TESTS. If no, go to next step.
  2. Turn ignition off. Using a 12-volt test light connected to 12 volts, probe Front Washer Motor harness connector terminal No. 2. Does test light illuminate brightly? If yes, go to next step.

Does test light illuminate brightly? If no, go to next step. If yes, repair open in Fused Ignition Switch Output circuit. Check Instrument Panel Junction Block C8 Fuse No. 5 (20-amp). If fuse is open, check Fused Ignition Switch Output circuit for a short to ground. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
