My Commander has auto power front windows (they go up and down automatically if you pull the switch through the notch). What is wrong when both driver and passenger window go all the way up (in auto mode) and then come down about half way? If I don't use the auto function, they go up and stay up, but in auto, they come back half way. This happens with either the master switch or the passenger switch. Has anybody encountered this problem?

Thanks in advance.

From the Service manual - You may need to have a calabration done? Or it may be sensing it thinks an object is in the window path and reverses for safety?​


"Another detent for the window up on both front window control switches in the master window switch and the front passenger switch activates the express up window feature for both front driver and passenger windows. The Driver Door Module (DDM) and Passenger Door Module (PDM) must be calibrated before this feature is enables. The window is calibrated at the factory. If a re-calibration is required stall the window in the full closed position for greater than 500 milliseconds."

Best I can tell, the windows anti-pinch safety feature is controlled by sensing the current draw of the motor. Which will change as the motor wears, and thus will need to be re-calibrated from time to time.

And the way your windows are reacting, it does sound like the control module is erronously sensing that the window encountered an obstacle before fully closing, thus reversing itself so as NOT to pinch someone's arm in the window.

The above procedure, in simplier terms. Close the window the whole way, pull up on the window switch the whole way and hold it at least a full second. You'll hear/feel the motor push the window against the stops for at least a full second after you release the switch. This will give the module a new value for the current drawn when the motor is powered but stopped (stalled). The windows auto up and down feature should work fine for a while.

If your motor is really wearing (or gumming up inside, which is how most window motors go bad) it will require this re-calibration more and more often.

2007 Commander--:> Every once in a while the passenger side window stays down ... a rapid lock-unlock of the power door locks a few times 'shakes' the insides of the passenger door and the electric motor then drives the window up. Probably just a little 'rust' on the commentator or button contacts.

If you slap the passenger door on the [meaning if you can reach the door]inside about where the electric motor is, she'll start to work again.
