One problem related to power window has been reported for the 2001 Nissan Nissan Truck. The most recently reported issues are listed below.
I own '01 Nissan xterra. In '03 I had to replace driver's side power window regulator. Feb. '05 remaining 3 regulators failed, all at the same time. One of the windows was in "down position" during heavy snow storm. It created signifficant distraction to a driver. Currently waiting for Nissan to do what's right and recal.
