Td4 tail gate window

I changed my battery on my td4 2006 56 and when I put new battery on the tailgate window went down half way and stayed there I tried it ting it back up and down but motor was going but window did not move and a beeping noise came on. I've tried the calibration thing but window don't move and now it just falls down when I put it up manually can anyone help

New window regulator mate. common fault in Freelanders.
Oh and they're easy to change if you buy them complete, a bu@@er if bought without motor and don't even think of buying a cable kit only.

Look for them in ebay.
