Washer System Inoperative

First check washer solution, hoses, pump, nozzles and bottle for proper attachment and condition, or screen (inside bottle) and nozzles for plugging.

1. If system components are satisfactory, turn ignition "ON" and dash switch to "LO" or minimum delay. Momentarily jumper No. 4 terminal to ground. If pump fails to operate, see step 2)  . If pump operates, check for open circuit in No. 4 (dash switch) wire. If circuit is not open, replace dash switch.
2. With ignition "ON", check for voltage at No. 4 and 5 terminals using a test light. With voltage at both terminals, see step 3)  . With no voltage at either terminal, check for open circuit between No 5 terminal (battery) lead and No. 2 terminal. With voltage at just one terminal, ratchet relay has open circuit and should be replaced.
3. Remove washer pump cover and reconnect wiring. Turn ignition "ON" and dash switch to "LO" or minimum delay. Check ratchet pawl for back and forth movement. If pawl moves back and forth, see step 4)  . If pawl does not move, check and repair or replace the cam follower or ratchet pawl spring.
4. With ignition "ON" and wiper running at low speed, push wash button to start wash cycle. If ratchet gear rotates, see step 5)  . If ratchet gear fails to rotate, replace ratchet gear and/or pawl as required.
5. Check piston movement through piston housing. If piston moves back and forth, replace valve assembly. If piston does not move, replace piston and pump housing assembly.
