Numbering of terminals of switches with increased operating frequency and with alternating cleaning and washing mode of glass
1. Switch with increased operating frequency
2. Switch with alternating glass cleaning and washing mode
Numbering of terminals of rear window wiper switch with increased operating frequency and with alternating cleaning and washing mode
1. High frequency rear window wiper switch
2. Rear window wiper switch with alternating wipe and wash mode
Examination
1. Disconnect the battery from ground.
2. Disable the airbag.
3. Remove the steering wheel.
4. Remove the steering column cover.
5. Disconnect the connector from the windshield wiper switch.
6. Check for continuity between the switch terminals (see Fig. Numbering of terminals of switches with increased operating frequency and with alternating windshield cleaning and washing mode and Fig. Numbering of terminals of rear window wiper switch with increased operating frequency and with alternating windshield cleaning and washing mode).
High frequency switch (in foggy conditions)
7. With the switch in the OFF position, the circuit should be between terminals 7 and 16.
8. With the MIST switch in the position, continuity should be between terminals 7 and 17.
9. In the LO switch position (weak move) the chain should be between terminals 7 and 17.
10. In the HI switch position (high speed) the chain should be between terminals 8 and 17.
Switch with alternating glass cleaning and washing
11. With the switch in the OFF position, the circuit should be between terminals 7 and 16.
12. With the MIST switch in the position, continuity should be between terminals 7 and 16.
13. In the LO switch position (weak move) the chain should be between terminals 7 and 17.
14. In the HI switch position (high speed) the chain should be between terminals 8 and 17.
Rear Window Wiper Switch
15. In the WASHER 1 switch position, the circuit should be between terminals 2 and 12.
16. In the OFF position of the switch there should be no current between all terminals of the circuit.
17. In the WIPER INT switch position, the circuit should be between terminals 2 and 13.
18. With the switch in the WIPER ON position, the circuit should be between terminals 2 and 10.
19. In the WASHER 2 switch position, the circuit should be between terminals 2, 10 and 12.
20. To test both types of switches, ensure that there is continuity between terminals 2 and 11 when the switch is in the ON position.
21. If the test results are negative, replace the switch.
Replacement
1. Remove the switch from the housing. To do this, unscrew the two screws (indicated by arrows). The switch has been removed from the steering column.
2. Installation is performed in the reverse order. Before installing the steering wheel, check the centering of the airbag wire coil (see subsection 9.14).
