Right Rear Power Window Switch Input Test

  1. Turn the ignition switch to LOCK (0).
  2. Remove the right rear power window switch (see POWER WINDOW MASTER SWITCH REPLACEMENT  ).
  3. Disconnect the 14P connector (A) from the right rear power window switch (B).

  4. 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 5.
  5. 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 6.
      TEST CONDITION AND WIRE REFERENCE CHART

      Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained
      2 GRY Driver's under-dash fuse/relay box connector X (39P) and passenger's MPCS unit connector A (28P) disconnected Check for continuity between terminal No. 2 and driver's under-dash fuse/relay box connector X (39P) terminal No. 15:
      There should be continuity.
      • Faulty passenger's under-dash fuse/relay box
      • An open or high resistance in the wire
      Check for continuity to ground:
      There should be no continuity.
      • Faulty passenger's under-dash fuse/relay box
      • A short to ground in the wire
      1 RED Connect terminals No. 8 and No. 1 with a jumper wire, and connect terminal No. 7 to body ground. Check the right rear power window motor operation:
      The motor should run (the window should go down).
      • Blown No. 5 (20 A) fuse in the passenger's under-dash fuse/relay box
      • Faulty right rear power window motor
      • An open or high resistance in the wire
      7 BLU Connect terminals No. 8 and No. 7 with a jumper wire, and connect terminal No. 1 to body ground. Check the right rear power window motor operation:
      The motor should run (the window should go up).
      • Blown No. 5 (20 A) fuse in the passenger's under-dash fuse/relay box
      • Faulty right rear power window motor
      • An open or high resistance in the wire
  6. Reconnect the connector to the right rear power window switch, 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 right rear power window switch must be faulty; replace it (see POWER WINDOW MASTER SWITCH REPLACEMENT  ) and go to step 7.
      TEST CONDITION AND WIRE REFERENCE CHART

      Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained
      6 BLK In all ignition switch positions Measure the voltage to ground:
      There should be less than 0.2 V.
      • Poor ground (G651)
      • An open or high resistance in the ground wire
      14 BLK In all ignition switch positions Measure the voltage to ground:
      There should be less than 0.2 V.
      • Poor ground (G651)
      • An open or high resistance in the ground wire
      8 PUR Under all conditions Measure the voltage to ground:
      There should be battery voltage.
      • Blown No. 22 (70 A) fuse in the under-hood fuse/relay box
      • Blown No. 5 (20 A) fuse in the passenger's under-dash fuse/relay box
      • Faulty passenger's under-dash fuse/relay box
      • An open or high resistance in the wire
      3 PNK Ignition switch ON (II) Measure the voltage to ground:
      There should be battery voltage.
      • Faulty right rear power window switch
      • An open or high resistance in the wire
      5 LT GRN Ignition switch ON (II) and right rear power window motor runs by connecting terminals No. 8 and No. 1 with a jumper wire, and connect terminal No. 7 to body ground. Measure the voltage between terminals No. 5 and No. 6:
      An analog meter should alternate between 0 V and about 5 V (a digital voltmeter reads about 2.5 V while the window moves).
      • Blown No. 5 (20 A) fuse in the passenger's under-dash fuse/relay box
      • Faulty right rear power window switch
      • Faulty right rear power window motor
      • An open or high resistance in the wire
      4 ORN Ignition switch ON (II) and right rear power window motor runs by connecting terminals No. 8 and No. 1 with a jumper wire, and connect terminal No. 7 to body ground. Measure the voltage between terminals No. 4 and No. 6:
      An analog meter should alternate between 0 V and about 5 V (a digital voltmeter reads about 2.5 V while the window moves).
      • Blown No. 5 (20 A) fuse in the passenger's under-dash fuse/relay box
      • Faulty right rear power window switch
      • Faulty right rear power window motor
      • An open or high resistance in the wire
  7. Reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT  ).
