Wipers Inoperative; Switch In Any Position
- Turn ignition on. Using a test light, probe Yellow/Blue wire at combination switch. If test light comes on, go to next step. If test light does not come on, repair open in Yellow/Blue between fuse block and combination switch.
- Probe Blue wire at combination switch with test light. Set wiper/washer switch in "LO" position. If test light comes on, check for open in Black wire between wiper motor and ground. Repair wire as necessary. If wire is okay, replace windshield wiper motor. If test light does not come on, replace combination switch.
