I have a problem like this and it's the rubber seal on the door becoming rigid over time. My front passenger door, below halfway gets stuck and unsets.
To set push button and have someone pull the window up to top hold for 5 seconds, then push down then hold for 5 seconds. A decent lubricating spray will help too

The assembly contains a feedback unit. The BeCM counts the number of pulses from full up to full down. That way it knows where the window is and when to shut off the power when the window is fully open or closed. 3 of the wires are for this with a fourth one being the earth. There's only two for the motor itself - Grey & Grey/Orange. The voltage to these two is just reversed to give both directions.

If you have replaced the motor, it could be the switch in the central consol that is the issue, you would need to look at the wiring diagram for the switch pack to see which wires to short circuit to move the window - if it is the switch a replacement swich pack from a breakers should be easy to find.

Doh - sorry didn't read that it was the rear window - no both switches would send a message to the BECM to operate the motor - it is a shame you do not have a Faultmate so that you could test the operation from the BECM....

The Faultmate is a superb diagnostic piece of kit available from Black Box Solutions. Expensive though but necessary to access the BeCM.
There are a couple of people on here you could send your BeCM to for testing and repair - one is Irish Rover and the other is Rick The Pick. You're better sending them a PM (private mail).
