Relay Switch Test
- If gear mechanism is in full-park position, install a small screwdriver into switch slot between drive pawl and latch arm. Push latch arm downward and toward relay switch coil in direction of arrow. See Figure.
- Remove washer pump assembly. Using test light, check for voltage at Black/Pink wire. If voltage exists, but motor does not operate, proceed to step 3). If voltage does not exist, relay switch and terminal board are defective.
- Disassemble motor section. Check for binding brushes, defective solder connections at brush holders, defective splice joints at field coil, open armature, defective circuit breaker ground connection on field lamination. Check for dirty or defective circuit breaker contacts or loose connections at circuit breaker terminals.
