Two problems related to power window have been reported for the 2001 Nissan Crew. The most recently reported issues are listed below.
Both passanger and driver power windows failed within 1 month of each other, in both cases the plastic cable cap broke off and allowed the windoe cable to wrap around the motor.
Power door windows begin "sticking" while powering up and eventually fail and get stuck. This happened on my friend's truck just 2 weeks before mine. Ours were manufactured just a few months apart and it happened on both of my windows (front) within a week of each other. A small plastic end on the wires used to "pulley" the windows breaks and allows the wire to wrap improperly around the window motor's internal pulley resulting in wires overlapping and eventually wedging within the motor. This shows me that this is a flaw in the manufacturers window motors on not only my frontier, but others I have met.
