Windshield Wiper Test 3A - Wipers Not Working In High Speed Mode

NOTE: Perform WINDSHIELD WIPER TEST 1A  before proceeding with this test. For connector terminal identification, refer to CONNECTOR IDENTIFICATION  . For wiring diagrams, refer to WIRING DIAGRAMS  . Perform, after each repair, VERIFICATION TEST VER-1A - VERIFICATION PROCEDURE  .
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Disconnect wiper HI/LO relay from Power Distribution Center (PDC). See Figure in EXTERIOR LIGHT TEST 2A. Using scan tool in voltmeter mode, measure voltage at terminal "C" on wiper HI/LO relay. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair or replace PDC.
  2. Connect a jumper wire between terminals "B" and "D" on wiper HI/LO relay socket. If wiper motor does not operate in high speed, leave jumper wire connected and go to next step. If wiper motor operates in high speed, go to step 4).
  3. Disconnect wiper module connector. Ensure connector is clean and not damaged. Using scan tool in voltmeter mode, measure voltage at terminal No. 3 (Red/Yellow wire) on wiper module connector. If voltage is more than 10 volts, replace wiper motor. If voltage is 10 volts or less, repair open in Red/Yellow wire between HI/LO wiper relay and wiper motor module.
  4. Disconnect jumper wire. Turn ignition off. Using scan tool in ohmmeter mode, measure resistance at terminal "A" on wiper HI/LO relay. Move wiper switch to HI position. If resistance is less than 5 ohms, replace wiper HI/LO relay. If resistance is 5 ohms or greater, go to next step.
  5. Disconnect multifunction switch. See Figure in CHIME TEST 4B. Connect jumper wire between ground and terminal No. 5 (White wire) on multifunction switch connector. Go to next step.
  6. Using scan tool in ohmmeter mode, measure resistance at terminal "A" on wiper HI/LO relay socket. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or greater, repair open White wire between PDC and multifunction switch.
  7. Remove jumper wire. Using scan tool in ohmmeter mode, measure resistance at terminal No. 8 (Black wire) on multifunction switch connector. If resistance is 5 ohms or greater, repair open Black wire. If resistance is less than 5 ohms, replace multi-function switch.
