Test 107A - Wiper Motor Intermittent Speed Operation
NOTE:
For connector terminal identification and wiring diagrams, see BODY CONTROL COMPUTER
section in this article. Perform TEST VER-1
VERIFICATION TEST after each repair.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
- Turn ignition on. Move wiper switch through all 6 different delay (intermittent speed) levels. If all delay levels do not fail, go to step 3). If all delay levels fail, go to next step.
- Using scan tool, read wiper switch status. Move wiper switch from OFF position through all 6 different delay levels. If scan tool voltage does not increase proportionally between INTRMT WIPE 0V and 5V (volts), replace multifunction switch. If scan tool voltage does increase proportionally, replace BCM.
- Using scan tool, read wiper switch status at failed intermittent wiper switch position(s). If voltage is present at failed position, replace BCM. If voltage is not present at failed position, replace multifunction switch.
