Master Switch Input Test
NOTE: The power window control unit is built into the power window master switch, and it only controls the driver'swindow operations.
1. Remove the window master switch {A) (see page 22-133).
2. Disconnect the 14P connector (B) from the master switch.

3. Inspect the co nnector and socket terminals to be sure they are all making good contact.
. lf theterminals are bent, loose orcorroded, repairthem as necessary, and recheckthe system.. lf the terminals look OK, go to step 4.
