    Tailgate window repair.

    Either follow the whole [How to] to repair a regulator or skip the middle section if you are replacing with a complete assembly.

    You will need, Philips screwdriver, 10mm & 13mm sockets, ratchet and an extension. Long nose pliers, T25 torx(if you are repairing the regulator), new tailgate membrane or gaffer tape.

    First off open the tailgate! Under the bottom of the trim there should be 4 screws,

    [​IMG]

    Remove these and them the tailgate trim can be pulled off starting in the corner where the screws were. The top edge is held on by u shaped clips -the trim lifts vertically off these when the rest of the clips are free.

    [​IMG]

    Remove the tailgate waterproof membrane,


    Now to start the strip down...

    [​IMG][​IMG]

    Loosen the 2 bolts securing the window clamps,

    [​IMG]

    Unplug and unclip the heated rear window wires.
    Then carefully lift the glass up out of the door and place in a safe place (away from dogs, children, clumsy mates etc.)

    Remove the two clamp bolts fully and retrieve the clamps and plastic bits from inside the door bottom.

    [​IMG]

    Loosen but don't remove the three bolts in the centre of the door retaining the window motor.

    [​IMG]

    Rotate the motor and push the bolt heads through the panel.

    [​IMG]
    [​IMG]

    Loose. But don't undo the two 10mm nuts at the top of each side slider. The second bolt is higher up and hidden in my pictures!

    [​IMG]

    Then undo and remove the 13mm nuts on each side at the bottom of the sliders.

    [​IMG]

    Un clip the wiring for the motor and pull the motor towards the hole in the door.

    [​IMG]

    You should now be able to unplug the motor wires.

    Wiggle the regulator assembly free.

    Either reassemble with a new regulator here or read the next bit about repair....


    Find somewhere warm (living room if wife will allow):jaw:




    Strip the old cable from the motor and sliders. If the aluminium has corroded and is preventing the cable from coming out some hot water will help wash the corrosion away.

    Get the nice new regulator kit out of its packet!

    Lay it all out and feed the parts together. I had a fight with one of the white end sections not going into the frame very easily, but with a bit of persuasion it pushed in. Also the d shaped section that retains the spring the hole was a little too small and had to be gently remedy out to fit.

    Feed the wires around the plastic wheel taking up all of the slack, Three hands can be useful for this! And pop into place on the motor....... Then have a fight with it so that the white plastic bits hook over the black plastic backing of the motor body. Making sure that the flat edge is upwards.

    Image

    Replace the metal section (slide it into the big white plastic bit and wiggle the small plastic section over it.

    Image

    Replace the bolts

    Image

    Have a cuppa - you have earned it!


    Take the unit back out into the cold.... And in the ubiquitous Haynes speak reassembly is the reverse of disassembly.

    Wiggle the regulator assembly into place and do up the bolts top and bottom and on the motor (referencing the marks on the door where it was originally)

    Image

    Reattach the clamps for the glass ensuring the plastic bit sit correctly.

    Drop the glass back into the door being very careful of the heated window terminals.

    Image

    Replace and re waterproof the door membrane.

    Refit the trim panel.

    Job is a good un. Now all you have to do is the re calibration procedure and you are all set.

    Hi did every thing you said BUT found a problem ...When my window cable broke it did so when the door was shutting...So window stayed up..So on your images plus the youtube video the replacement of the cables are for a window or cable broken DOWN ...So when I did everything put it back pressed the button the cable broke again as the window was down and the motor was set to take it down from being up where it broke ...So ,if I do this again I do I reset the motor so that it lifts up and not down.

    If you can reach the bolts holding the glass then loosen them and lift the glass up, then it should be easy to get out.

    Be careful while taking off the rear window heater connector. They break off the window very easily.

    Fitted new regulator. Problem is the longstanding marks on the glass where the old glass clamps bear no relationship to the new glass clamps. I have spaced them out as equally as I can. Window is not level and offset. When recalibrating the window keeps going down and when raising it stops several times on the way up and three beeps can be heard each time. It will not sit snugly at the top in the closed position. Stays up with ignition off, opening door causes window to drop down What do I do next?

    First thing is to get it level by loosening the bolts and adjusting as best you can. Then disconnect the battery so that when you reconnect it the rear window will automatically go all the way down. Then turn the ignition on and bring it back to the top, this should re-calibrate your window.

    Finally got it level. Tried recalbration procedure 12 times and gave up. Locked the Freelander and went to bed. Got up in morning and everything was the same plus it refused to start! An hour later it roared into life and the window operated perfectly! Puzzling! Thanks for the suggestions anyway it all helped.
