    Does anyone know what would cause the
    sunroof on a 2001 V70XC to operate eratically?
    The switch doesn't seem to be the problem
    and a new power module was put in for a
    test but that didn't solve the problem

    Is there a relay or circuit-breaker in the
    system that controls the sunroof? I read
    something about a software problem causing
    power windows troubles in the V70. Does anyone
    know if there is a reset procedure? Thanks.

    Try this.
    Close all of the doors and hood.
    Key in pos II engine not running.
    Hold both the driver window and passanger
    window switches in the driver door panel in the closed or
    up position for 5 to 8 seconds after the windows are closed.
    Release buttons.
    Remove the ignition key.
    Operated the remote twice. lock/unlock lock/unlock.
    This will reset the UEM brain.
    This can correct faulty operation of the sunroof
    and/or erratic door lock function.

    Using the key in the drivers door to lock/unlock
    lock/unlock will also reset the UEM ----
    Upper Electronic Module.

    Thanks. The procedure worked very well. No
    more problems with the sunroof. It goes back
    and forth properly.
