- Remove the power window master switch (see «POWER WINDOW MASTER SWITCH REPLACEMENT»(ref-513206-S19193195592012110700000) ).
- Disconnect the 22P connector (A) from the power window master switch (B).
- Inspect the connector and socket terminals to be sure they are all making good contact. If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system. If the terminals look OK, go to step 4.
- With the connector still disconnected, do the following input tests: If any test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, go to step 5.

- Remove the power window master switch (see «POWER WINDOW MASTER SWITCH REPLACEMENT»(ref-513206-S19193195592012110700000) ).
- Disconnect the 22P connector (A) from the power window master switch (B).
- Check for continuity between the terminals in each position according to the tables. Front Passenger's Switch Left Rear Switch Right Rear Switch 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 power window master switch input test procedures (see «POWER WINDOW MASTER SWITCH INPUT TEST»(ref-513206-S10718363042012110700000) ). If the tests are normal, the driver's switch must be faulty; replace the power window master switch.
- If the continuity is not as specified, replace the switch (see «POWER WINDOW MASTER SWITCH REPLACEMENT»(ref-513206-S19193195592012110700000) ).
