1. Turn ON the ignition, with the engine OFF.
2. Attempt to operate the power windows from both the driver door switch, and, from each one of the window switches mounted to the passenger doors.

Does any window operate?

Go to Power Windows Inoperative - One

Go to Step 3

1. Remove the PWR WDO circuit breaker from the underhood fuse block.
2. Probe the circuit breaker battery supply terminal with a test lamp connected to a good ground.

Does the test lamp illuminate?

Go to Step 4

Go to Step 8

Test the circuit breaker for an open or high resistance.

Was the circuit breaker found to be open or have a high resistance?

Go to Step 5

--

1. Turn OFF the ignition.
2. Disconnect all of the door modules.
3. Test the battery positive window supply circuit contained in each door modules connector C2 for an open or a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

1. Reinstall the PWR WDO circuit breaker.
2. Turn ON the ignition, with the engine OFF.
3. Reconnect the door modules, one at a time, attempting to operate the window associated with each module as each module is reconnected.
4. If, after reconnecting a module, the associated window operates, proceed to reconnecting the next module.

Did any window not operate after its module was reconnected?

Go to Step 7

Go to Step 10

Inspect for poor connections/terminal tension at the harness connector of the inoperative door module. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?
