Wiper Park Switch Failure (Except Sebring Convertible)
- Turn ignition on. Record and erase any trouble codes in Body Control Module (BCM). Operate wipers in LOW, HIGH and all intermittent positions. Turn wipers off and activate washers. If wiper park switch DTC sets, go to next step. If wiper park switch DTC does not set, go to step 6.
- Operate wiper in intermittent mode. Using scan tool, select MONITOR DISPLAY, WIPER SYSTEM and observe wiper park switch. If wiper park switch does not toggle from closed to open, turn wipers off and go to next step. If wiper park switch toggles from closed to open, system is operating properly. Using scan tool, clear trouble codes, and try to reproduce fault.
- Turn wipers off. Disconnect wiper motor Light Gray 4-pin connector and ensure connector is clean and not damaged. Using scan tool, continue observing wiper park switch. Connect a jumper wire between ground and wiper motor 4-pin connector terminal "D" (Tan/Red wire). See Fig 1. If scan tool does not display SWITCH: CLOSED, go to next step. If scan tool displays SWITCH: CLOSED, replace wiper motor. See appropriate WIPER/WASHER SYSTEMS article.
- Locate BCM 14-pin connector C1. See Figure. Using a jumper wire, backprobe between ground and BCM 14-pin connector C1 terminal No. 2 (Tan/Red wire). See CONNECTOR IDENTIFICATION . If scan tool does not display SWITCH: CLOSED, go to next step. If scan tool displays SWITCH: CLOSED, repair open in Tan/Red wire. See WIRING DIAGRAMS .
- Replace BCM. See BODY CONTROL MODULE (BCM) under REMOVAL & INSTALLATION.
- Turn ignition on. Using scan tool, monitor wiper voltage. Move wiper switch through all 6 intermittent positions. If voltage changed while moving switch through intermittent positions, replace BCM. See BODY CONTROL MODULE (BCM) under REMOVAL & INSTALLATION. If voltage did not change while moving switch through intermittent positions, replace multifunction switch. See appropriate STEERING COLUMN SWITCHES article.
