My 2005 Mustang's driver side window recently stopped closing itself automatically when the door is closed. Anyone know what is causing it to not move up on it's own? Does it have it's own separate fuse? Or is it something electrial within the confines of the door?

 

I personally have not experienced this, however from what I've read in the past, there is a way to recalibrate the windows. Try using the search function and see what you can come up with.
Also, those that have experienced this issue may chime in as well.
Good luck!

 

I located this thread. Worth a try!

Exactly as kevin said, you roll it up and hold for a few seconds then roll it down and hold it for a few seconds.

Had to do it when my battery died.

 

The recalibration procedure is described in the OM.

 

The 'brains' for the windows resides on the window motors themselves.

The motor can be de-initialized in 2 ways:
Disconnect the battery cable from the battery while the window is operating.
Remove the window motor fuse while the window is operating.
After the motor has been de-initialized, reconnect/reinstall the battery cable or fuse and carry out the initialization procedure.
Initialization


WARNING: Keep objects and body parts clear of the glass panel when carrying out the initialization procedure. During the initialization procedure, the glass panel closes with high force and cannot detect objects in its path. Failure to follow this instruction may result in serious personal injury.

NOTE: If this procedure is only partially completed, the front window motor remains non-initialized and may allow one-touch down operation, but does NOT allow one-touch up operation.

NOTE: The door MUST be closed during this procedure (for convertibles, the top and quarter glass must be in the CLOSED and UP position) in order for the door window motor to initialize.

NOTE: The windows must be in the full OPEN position for this procedure to operate correctly.

Press and hold the window control switch in the UP position at the second detent until the window glass stalls into the glass top run for at least 2 seconds.
Once the top run is reached, hold the window control switch in the DOWN position at the second detent until the window glass stalls at the bottom of its travel for at least 2 seconds.
Cycle the window glass up and down once more to set the window soft stop for the DOWN position.
Test for correct window operation by carrying out the one-touch up and one-touch down features.
