    Default issue with passenger side power window

    In the past my passenger side power window was what I'd call "lazy" meaning it would sometimes not function from the master driver side switch but always works on the passenger side switch.

    Usually I would just hit the passenger side switch for a few seconds and then the master switch would again have control. Its only the passenger side front window that does this. All three other windows function correctly at the master switch and at the passenger switches.

    Today the passenger front finally crapped out from the driver master switch entirely. And its a NOS Motorcraft switch not old at all.

    Anybody else seen this behavior?

    The motors often get weak with age. I find if you rev. the engine to 8ncrease 5ne voltage level, gets them to respond. Replacing the motor is the fix.
