I have an 02 discovery 2 and the left front window will go down and up sometimes. sometimes it works great then others it will go down but not back up. I replaced the motor and regulator still no difference. I tried other switches still no difference. all my other windows work perfect.
Any ideas would be helpful. I think its electrical for example a ground or an ecu of some sort that may be part of the system.


The left front window started working this morning but it still doesn't seem 100 percent. It goes up slow and hesitant in some spots.
Now my right front window won't work. The switch is good.


I see a computer and some other computer type boxes behind the gloves box on passenger side. There are 2 black boxes with multiple plugs on them. one has different colored plugs all on the bottom (both black boxes are mounted on their sides). The other black box has wires going in the top of it and several plugs on its side. What are these boxes?


Need help with this problem. I am in the army and moving to Germany. I can't take the vehicle with me so I need to sell it but I don't want to sell it with issues to someone.
