The rear window went down a couple of inches and wont stay up

The motor is going bad and or the plastic track that actually does the lifting and lowering of the window ( i forget the exact name of it ) is going bad However if you replace the window motor you will need to replace that " track " too .But i think the motor for your window is about done At some point it just wont do anything at all

its lost its memory ,hold key in lock and close window then holding key in closed position for 10 secs should reset the memory in the electronic control box on the window motor memory inside this control box

This a fairly common problem with Altimas. Unfortunately you'll probably have the best luck just taking it to the dealer as the windows are controlled by a computer and certain functions need to be programmed by a dealer only tool. I know that part of your problem is related to a function in the system that prevents hands from being trapped in the window when it is closing. The idea is if the window is going up and it feels an obstruction before it reaches the top, it backs down a couple of inches. This means that the window needs to know where the top and bottom of it's travel is, which is done through programming. It also means that if the window track gets sticky and the computer thinks that it's hitting an obstruction, it will back down a couple inches when you're in the middle of trying to go up. For a temporary way of dealing with it, I've found that quick blips on the up button will allow you to get past the invisible "hand" that the computer thinks is in the way.

Hope this helps,

My 2002 alero rear right window will go down but wont come back up what do i do... Help

THERES A TIMEING SEQUINCE YOU HAVE TO DO THE MANUL MIGHT SAY HOW

youneed a new window motor cost anywhere from a couple of hundred to a couple grand

you will have to replace the whole regulator. check with your local used parts dealer for cheapest price. those regulators can range from 100 to 300 dollars and in some cause more. also for temp solution shove a piece of cardboard between inside window felt and glass to create pressure. it will help hold it up through the bumps

The Regulator will fix the problem. The tracks might also need a little adjustment.(loosen bolts move track then retighten) Try holding the window while you are rasing it you might be able to guide it up so that it will close a bit more.

I Had this happen to me . turn out to be driver side main switch bad to that door.

try a hard restart, if that doesnt work then you need a new rear window motor. for the hard restart all you have to do is disconnect the battery cables and touch the positive and negative together for about 8 seconds. if that fails then a new motor it is.
