Test 26B - Repairing Wiper Switch, Controller & Power Supply

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAMS  . Perform TEST VER-1 after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting any module connector.
  1. Using DRB, actuate wiper motor low speed test. If wiper motor operates in low speed mode, go to TEST 26C  . If wiper motor does not operate in low speed mode, go to next step.
  2. Stop wiper motor low speed mode actuation test. Using DRB, actuate wiper motor high speed test. If wiper motor operates in high speed mode, go to TEST 26C. If wiper motor does not operate in high speed mode, go to next step.
  3. Stop high speed mode actuation test. Access Power Distribution Center (PDC). PDC is located on left front fender apron. Inspect "C" cartridge fuse in PDC. See Figure . If fuse is blown, go to TEST 26C. If fuse is okay, go to next step.
  4. Remove "C" cartridge fuse from PDC. Using DRB in voltmeter mode, check voltage on "C" cartridge fuse connector (Black wire). If voltage is less than 10 volts, repair open Black wire between "C" cartridge fuse and battery positive terminal. If voltage is more than 10 volts, go to next step.
  5. Install "C" cartridge fuse. Remove on/off wiper relay (relay No. 6) from PDC. Using DRB in voltmeter mode, check voltage on on/off wiper relay connector terminal "D" (Red/Dark Blue wire). If voltage is less than 10 volts, repair open Red/Dark Blue wire between "C" cartridge fuse and on/off wiper relay. If voltage is more than 10 volts, go to next step.
  6. Connect jumper wire between on/off wiper relay connector terminals "B" (Light Green/Black wire) and "D" (Red/Dark Blue wire). If wiper motor operates, go to TEST 27A  . If wiper motor does not operate, go to next step.
  7. Remove high/low wiper relay (relay No. 10) from PDC. Ensure jumper wire is still connected between on/off wiper relay connector terminals "B" (Light Green/Black wire) and "D" (Red/Dark Blue wire). Using DRB in voltmeter mode, check voltage on high/low wiper relay connector terminal "B" (Light Green/Black wire). If voltage is less than 10 volts, repair open Light Green/Black wire between on/off wiper relay and high/low wiper relay. If voltage is more than 10 volts, go to next step.
  8. Remove jumper wire from on/off wiper relay terminals. Connect jumper wire between on/off wiper relay connector terminal "D" (Red/Yellow wire) and high/low wiper relay connector terminal "E" (Brown/White wire). If wiper motor does not operate in low speed mode, go to TEST 28A  . If wiper motor operates in low speed mode, go to next step.
  9. Remove jumper wire from on/off wiper relay and high/low wiper relay terminals. Using DRB in voltmeter mode, check voltage on on/off wiper relay connector terminal "A" (Dark Blue wire). If voltage is less than 10 volts, go to TEST 29A  . If voltage is more than 10 volts, go to next step.
  10. Using DRB, actuate wiper motor in low speed mode. Using DRB in voltmeter mode, check voltage on on/off wiper relay connector terminal "C" (Dark Green/Yellow wire). If voltage does not pulsate between zero and more than 0.2 volt, go to step 12). If voltage pulsated between zero and more than 0.2 volt, go to next step.
  11. Install on/off wiper relay in PDC. Using DRB in voltmeter mode, check voltage on high/low wiper relay connector terminal "B" (Light Green/Black wire). If voltage does not pulsate between zero and battery voltage, replace on/off wiper relay. If voltage pulsates between zero and battery voltage, replace high/low wiper relay.
  12. Access Body Control Module (BCM). BCM is located behind right kick panel. Using DRB, actuate wiper motor in low speed mode. Using DRB in voltmeter mode, backprobe BCM Bone connector terminal No. 1 (Dark Green/Yellow wire). If voltage pulsates between zero and more than 0.2 volt, repair open Dark Green/Yellow wire between BCM and on/off wiper relay. If voltage does not pulsate between zero and more than 0.2 volt, replace BCM.
