Express Window Programming and Setup

Anytime battery power is lost or if the rear electrical center is replaced, the express down feature must be relearned.

Follow the procedure below to program the power windows:

    • Ignition ON, lower each window to the full down position and hold each window switch at the full down position for 5 seconds.
    • Raise each window to the full up position and hold each window switch at the full up position for 5 seconds.
    • Ignition OFF and remove key.
    • Close all doors and command all doors to LOCK by using remote keyless entry (RKE) transmitter.
    • Command all doors to UNLOCK by using the RKE transmitter.
    • Verify that the express down feature is working by holding the unlock button on the RKE transmitter. If the express down function is successfully relearned, all power windows should roll completely down.
