Driver's Switch:
The driver's switch is combined with the control unit so you cannot isolate the switch to test it. Instead, run the master switch input test procedures. If the tests are normal, the driver's switch must be faulty.
4. If the continuity is not as specified, replace the switch.
5. If the switch is faulty, replace the switch by removing the three mounting screws and the switch (A).
