Wiper Not Working In High Speed

NOTE: After making any repairs, perform BODY CONTROL MODULES SYSTEM VERIFICATION TEST  under VERIFICATION TESTS.
  1. Turn ignition off. Remove wiper high/low relay from Power Distribution Center (PDC). See Figure . Connect a jumper wire between wiper high/low relay connector terminal "A", fused B+ circuit (Red/Orange wire) and terminal "D", wiper high/low relay high speed output circuit (Red/Yellow wire). If windshield wipers operate at high speed, leave wiper high/low relay removed, and go to next step. If windshield wipers do not operate at high speed, leave wiper high/low relay removed, and go to step  6 .
  2. Remove jumper wire. Substitute a known-good wiper high/low relay. Turn ignition on. Operate wipers in low, then high speed. If wipers operate properly, replace wiper high/low relay. If wipers do not operate properly, install original wiper high/low relay, and go to next step.
  3. Turn wipers off. Turn ignition off. Disconnect multifunction switch connector. Remove multifunction switch from steering column. Set multifunction switch in high position. Measure resistance between multifunction switch (component side) terminals No. 1 and 3. See Figure . If resistance is 480-540 ohms, go to next step. If resistance is not 480-540 ohms, replace multifunction switch.
  4. Remove wiper high/low relay. Disconnect Body Control Module (BCM) connector C3. Turn ignition on. Measure voltage on BCM connector C3 terminal No. 12, wiper high/low relay control circuit (Violet wire). See Figure . If any voltage exists, repair short to voltage in Violet wire. If no voltage exists, leave wiper high/low relay removed, BCM connector C3 disconnected, and go to next step.
  5. Turn ignition off. Measure resistance of wiper high/low relay control circuit (Violet wire) between BCM connector C3 terminal No. 12 and high/low relay connector terminal "C". If resistance is less than 5 ohms, replace BCM. If resistance is 5 ohms or more, repair open in Violet wire.
  6. Remove jumper wire. Turn wipers off. Connect a 12-volt test light between ground and wiper high/low relay connector terminal "A", fused B+ circuit (Red/Orange wire). If test light illuminates brightly, leave wiper high/low relay removed, and go to next step. If test light does not illuminate brightly, repair open in Red/Orange wire.
  7. Disconnect wiper motor connector. Connect a fused jumper wire between ground and wiper motor connector terminal No. 1, wiper relay high speed output circuit (Red/Yellow wire). See Figure . Connect 12-volt test light between battery voltage and wiper high/low relay connector terminal "D", wiper relay high speed output circuit (Red/Yellow wire). If test light illuminates brightly, leave wiper high/low relay removed, wiper motor connector disconnected, and go to next step. If test light does not illuminate brightly, repair open in Red/Yellow wire.
  8. Measure resistance between ground and wiper motor connector terminal No. 1, wiper relay high speed output circuit (Red/Yellow wire). If resistance is less than 100 ohms, repair short to ground in Red/Yellow wire. If resistance is 100 ohms or more, replace wiper motor.
