Test 2, Wipers Won't Shut Off; Blades Operate In Normal Wipe Pattern
- With wipers in delay mode and wipers do not delay between wipes, go to test step 2). If wipers delay between wipes, turn ignition on and turn wiper switch to off position. Remove connector from terminals 1, 2 and 3. Connect 12-volt test light between terminals 1 and 2. If test light goes off, go to test step 3). If test light stays on, check for grounded wire between wiper switch and terminal 1, or defective wiper switch.
- With wiper switch off, turn ignition off and then on. If wipers do not shut off, check if override switch contacts are opened by projection on rim of ratchet gear. If contacts open, check for grounded Blue wire. If contacts close, check for loose timing circuit attaching screw. If okay, adjust contacts or replace timing circuit assembly. See Fig 1 .
- Remove washer pump assembly and check park relay spring. If connected, replace park relay. If wipers shut off and blades park correctly, check holding switch contacts, and adjust contacts. If okay, replace timing circuit assembly.
