DEFINITION: This diagnostic table is for problems with rear power windows only. Refer to Power Window Inoperative from Master Switch for front window diagnostics.

Did you perform the Diagnostic System Check for the door system?

Go to Step 2

Go to Diagnostic System Check - Door Systems

1. Turn ON the ignition, with the engine OFF.
2. Make sure the window lockout feature is not enabled.
3. Verify that at least one of the rear power windows is inoperative.

Do the rear windows operate properly?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 3

Does the inoperative window operate from the master window switch?

Go to Step 4

Go to Step 5

1. Disconnect the window switch that is in the door that has the inoperative window.
2. Connect a test lamp between the positive voltage feed circuit at the switch connector and a good ground.

Does the test lamp illuminate?

Go to Step 13

Go to Step 9

1. Disconnect the window switch that is in the door that has the inoperative window.
2. Connect a test lamp between the up control feed circuit at the switch connector and the down control feed circuit at the switch connector.
3. On the master switch, press the appropriate window switch to the up position then to the down position.

Did the test lamp illuminate when the switch was pressed to the up position or the down position?

Go to Step 6

Go to Step 10

Did the test lamp illuminate when the switch was pressed to the up position and the down position?

Go to Step 7

Go to Step 11

1. Reconnect the window switch disconnected earlier.
2. Disconnect the inoperative window motor connector.
3. Connect a test lamp between the control circuits of the inoperative window motor connector.
4. On the master switch, press the appropriate window switch to the up position then to the down position.

Does the test lamp illuminate for the up condition or the down condition?

Go to Step 8

Go to Step 12

Did the test lamp illuminate when the switch was pressed to the up position and the down position?
