Windshield Wiper Test 7A - Wiper Wash Function Not Working Properly

WARNING: This page is about a different car, the 1995 Dodge Stratus and 1995 Chrysler Cirrus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform WINDSHIELD WIPER TEST 1A  before proceeding with this test. For connector terminal identification, see CONNECTOR IDENTIFICATION in BODY CONTROL COMPUTER INTRODUCTION. Perform TEST VER-1A  after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Ensure windshield washer fluid reservoir is full. Momentarily pull and release wash button. If washer pump did not operate and wipers did operate, go to next step. If washer pump and wipers did not operate, go to step 5). If washer pump operated without wiper operation, replace BCM. If washer pump and wipers operated, system is operating properly.
  2. Locate washer pump 2-pin connector at bottom of washer fluid reservoir and disconnect 2-pin connector. Ensure connector is clean and not damaged. Using scan tool in ohmmeter mode, check resistance of washer pump connector terminal No. 2 (Black wire). If resistance is less than 5 ohms, go to next step. If resistance is more than 5 ohms,repair open in Black wire.
  3. Activate washer pump switch. Using scan tool in voltmeter mode, check voltage on washer pump 2-pin connector terminal No. 1 (Brown/Dark Blue wire). If voltage is less than 10 volts, go to next step. If voltage is more than 10 volts, replace washer pump.
  4. Locate engine 14-pin connector at BCM. See Figure in CHIME TEST 3A  . Activate washer pump switch. Using scan tool in voltmeter mode, backprobe engine 14-pin connector terminal No. 10 (Brown/Dark Blue wire) and check voltage. If voltage is more than 10 volts, repair open Brown/Dark Blue wire. If voltage is less than 10 volts, replace BCM.
  5. Using scan tool, read washer switch status while pulling washer switch. If scan tool does not display WASHER SW: CLOSED, go to next step. If scan tool displays WASHER SW: CLOSED, replace BCM.
  6. Locate and disconnect right multifunction switch 7-pin connector. See Figure in INSTRUMENT CLUSTER TEST 5G. Connect a jumper wire between multifunction switch 7-pin connector terminals No. 1 (Dark Blue wire) and No. 3 (Brown/Dark Blue wire). Using scan tool, read washer switch status while pulling washer switch. If scan tool does not display WASHER SW: CLOSED, go to next step. If scan tool displays WASHER SW: CLOSED, replace multifunction switch.
  7. Disconnect instrument panel 22-pin connector at BCM. See Figure in CHIME TEST 3A  . Ensure connector is clean and not damaged. Using scan tool in voltmeter mode, check voltage on instrument panel 22-pin connector terminal No. 15 (Brown/Dark Blue wire). If voltage is more than 10 volts, replace BCM. If voltage is less than 10 volts, repair open in Brown/Dark Blue wire.
