Official summary
Some customer's may complain that the front power window(s) do not operate after the vehicle has been parked outside during freezing temperatures. This may be caused by water that infiltrates into the power window regulator and freezes in the drum groove for the cable. Then when the power window is operated, the cable slips out from the ice-filled groove and tangles, blocking further window operations.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
