1. Turn the ignition switch to LOCK (0), and remove the power window master switch (see «POWER WINDOW MASTER SWITCH REPLACEMENT»(ref-333619-S07541619552009072100000) ).
2. Disconnect the 37P connector (A) from the power window master switch (B).
3. 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 .
4. With the connector still disconnected from the power window master switch, do the following input tests. If any test indicates a problem, find and correct the cause, then recheck the system.
