1996 Land Rover Discovery Transmission and ABS Light and Window

I just bought a 1996 Land Rover Discovery Automatic Transmission and 88k miles and I have 3 current problems I need to address.

#1 The ABS Light is On. How can I trouble shoot this?

#2 The passenger side window only goes down a few inches and gets stuck. But goes back up fine.

#3 After i lift my foot off of accelerator the vehicle jerks once or twice and then runs ok at any speeds

hi m8,1 will need diagnostic check to see what the problem is,2 most probably the window regulator is damaged,3 need a bit more info on the problem? your a little vaige in your explanation.

i bought a 300tdi auto had same problem on abs had to have diagnostics on abs found air gap needed adjusting on sensor been fine since wheel on window regulator tends to break did on mine week after buying it was told more of a poblem on drivers window easy to do not had the other problem though
