The window will often fall down on a 2001 Nissan Xterra due to a faulty drive motor. This causes the tension that holds the window in place to release.
Write down the VIN number of your vehicle, then call the dealer and ask them.
There is actually two O2 sensors. One is located on the down pipe from the engine by the NO 1Catalytic converter. The other is further down the pipe toward the muffler about half way down the pipe
I had same problem on my 2000 Nissan Xterra. You probably need to replace the power window switch assembly. I did the same on my car and it works fine now. Go to http://catalog.nissanpartswholesale.com and look for part number O3060-177168 ($89.60). I'm not sure how far it goes back but there was a recall/service bulletin on my '01 Xterra for the same problem. They replaced all 4 of the assemblies at no charge. Might be worth a call to the local dealership.
you can try WD-40 on window edges, but usually need to take off door panel and check the cable. I had this happen to 3 out of 4 windows and the motors were ok but had to replace the cable arm they are about $60.00

Sounds like the window regulator. Mine did the same thing changed that and no more problems, it cost about 75.00 for the part.
A standard twin mattress will fit into an xterra. You must fold down the seats and adjust the front seats a few inches forward but I managed to fit an entire bed in there.
Not to be smart but you can find out in 5 seconds. Get down on your knees, look under the vehicle and count them.
The SE has the upgraded interior, moon roof (pretty useless), and the full exterior upgrades - mag wheels, rubber door protectors etc. The XE is anything else and varies from the stripped down 4 cylinder, manual transmission to the V6 4x4 with various options.
Based on symptom: switch or motpr Based on Nissan: switch Replace Nissan window switches frequently lest you be caught open in the rain.
