NOTE: The power window control unit is built into the power window master switch.
-
-
Disconnect the 22P connector (A) from the power window master switch.
-
Inspect the connector and socket terminals to be sure they are all making good contact.
-
With the connector still disconnected, make these input tests at the connector.
NOTE: Before testing, make sure the No. 1 (10 A), No. 22 (7.5 A), and No. 60 (50 A) fuse in the under-dash fuse/relay.
