Power Window Master Switch Input Test

NOTE:
  • The power window control unit is built into the power window master switch.
  • Before testing, check the No. 1 (7.5 A), No. 3 (20 A), No. 17 (20 A), No. 18 (20 A), No. 19 (20 A), No. 22 (7.5 A), and No. 60 (IGN) (50 A) fuses in the under-dash fuse/relay box.
  1. Remove the power window master switch (see POWER WINDOW MASTER SWITCH REPLACEMENT ).
  2. Disconnect the 22P 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, 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.

  5. Reconnect the connector to the power window master switch. Turn the ignition switch to ON (II), and 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, the control unit must be faulty; replace the power window master switch (see POWER WINDOW MASTER SWITCH REPLACEMENT ).
      NOTE: After replacing the power window master switch, reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT ).
