Power Window Master Switch

INSPECTION

1. INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY









a. Using an electrical tester, check if the diodes are functioning normally.

If the result is not as specified, replace the master switch assembly.

b. Using an electrical tester, check if the diodes are functioning normally.

HINT:
- As the switch has diodes, a resistance inspection cannot be performed. Use the tester's diode check function to check the diodes.
- Connect the tester's leads as shown in the table below. If the leads are not connected correctly, the readings will not be accurate. Connect the tester's positive (+) lead to the diode's positive (+) side, and the negative (-) lead to the diode's negative (-) side.

1. Set the function selector switch to diode check function mode, and check that the diodes are functioning normally.









If the result is not as specified, replace the master switch assembly.

c. Check the window lock switch.





If the result is not as specified, replace the master switch assembly.
