Intermittent Wipers Inoperative

NOTE: For connector terminal identification and wiring diagrams, see BODY CONTROL COMPUTER - INTRODUCTION article. Perform VERIFICATION TEST VER-1A  after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Connect scan tool to Data Link Connector (DLC). DLC is a 16-pin connector located under left side of dash, to left of steering wheel. Turn ignition switch to ON position. If scan tool display is not blank or have a CCD bus failure message, go to next step. If scan tool display is blank or has a CCD bus failure message, see appropriate VEHICLE COMMUNICATIONS article.
  2. If problem is wipers parking in wrong position, go to step  5 . If problem is not wipers parking in wrong position, go to next step.
  3. Gain access to wiper motor connector. Turn wipers on to low speed. Using an external voltmeter, measure voltage between ground and wiper motor switch terminal No. 2 (Dark Green/Yellow wire). If voltage does not cycle between zero and 12 volts, replace wiper motor. If voltage cycles between zero and 12 volts, go to next step.
  4. Locate Central Timer Module (CTM). CTM is located behind right kick panel. Using an external voltmeter, measure voltage between ground and backprobe of CTM 14-pin Green connector "A" terminal No. 11 (Dark Green/Yellow wire). Wipers should be operating at low speed. If voltage does not cycle between zero and 12 volts, repair open Dark Green/Yellow wire between CTM and wiper relay or park switch. If voltage cycles between zero and 10 volts, replace CTM.
  5. Using scan tool, monitor intermittent wiper voltage level. Rotate wiper switch from low intermittent to high intermittent level. If voltage changes from approximately 2.5 to 12 volts, replace CTM. If voltage does not change from approximately 2.5 to 12 volts, go to next step.
  6. Disconnect 24-pin multifunction switch connector. Using an external ohmmeter, measure resistance of White wire between multifunction switch connector terminal No. 1 and CTM 14-pin Green connector "A" terminal No. 12. If resistance is less than 5 ohms, replace multifunction switch. If resistance is 5 ohms or more, repair open White wire between multifunction switch and CTM.
