Test 32A - Wiper Motor Low Speed Operation

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. Turn ignition switch to OFF position. Turn wiper switch off. Ensure all doors are closed and courtesy lamps are off. Wait one minute. Gain access to Body Control Module (BCM). BCM is located behind right kick panel. Go to next step.
  2. Using DRB in ohmmeter mode, backprobe BCM Bone connector terminal No. 16 (Dark Green/Red wire). If resistance is not 1100-1400 ohms, go to TEST 33E  . If resistance is 1100-1400 ohms, go to next step.
  3. Turn ignition switch to ON position. If wipers operate at one speed continuously without stopping in park regardless of switch position, go to TEST 31B  . If wipers do not operate at one speed continuously without stopping in park regardless of switch position, go to next step.
  4. Using DRB, actuate wiper motor low speed then high speed. If wiper motor actuates in both tests at same speed, go to TEST 32B. If wiper motor does not actuate in both tests at same speed, go to next step.
  5. Stop actuation test. Using DRB, actuate wiper motor low speed. If wiper operates in low speed mode, replace multifunction switch. If wiper does not operate in low speed, go to next step.
  6. With DRB still actuating low speed, if wiper motor is not operating in high speed, go to TEST 32D  . If wiper motor is operating in high speed, go to next step.
  7. Stop actuation test. Remove high/low wiper relay (relay No. 10) from Power Distribution Center (PDC). PDC is located on left front fender apron. See Figure . Using an external ohmmeter, check resistance between high/low wiper relay terminals "B" and "D". If resistance is less than 5 ohms, replace high/low wiper relay. If resistance is more than 5 ohms, go to next step.
  8. Turn ignition switch to OFF position. Gain access to Body Control Module (BCM). BCM is located behind right kick panel. Disconnect BCM Bone connector. Using DRB in ohmmeter mode, check resistance of BCM Bone connector terminal No. 18 (Violet wire). If resistance is less than 5 ohms, repair short to ground in Violet wire. If resistance is more than 5 ohms, go to next step.
  9. Remove on/off wiper relay (relay No. 6). Using an external ohmmeter, check resistance between BCM Bone connector terminals No. 1 (Dark Green/Yellow wire) and No. 18 (Violet wire). If resistance is less than 5 ohms, repair short between Dark Green/Yellow wire and Violet wire. If resistance is less than 5 ohms, replace BCM.
