Power Window Master Switch Input Test

NOTE: The power window control unit is built into the power window master switch.
  1. Disconnect the 22P connector (A) from the power window master switch.
  1. 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 .
  1. With the connector still disconnected, make these input tests at the connector.
    • 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 .
    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.
