On Thursday 1st May (hottest day of the year so far), I opened the drivers side door window but found it would not close although I can hear the motor running both to open and close very briefly. Is it possible to remove the inner door panel to inspect the mechanism. With only 28,000 genuine miles on the clock from new, I can't think it is wear and tear. This is the first problem I have had in 10 years of ownership. Please advise.

Hi Leslie, that sounds like an unfortunate experience. Yes, it is possible to remove the door card - what you refer to as the inner door panel - but you will require the correct trim tools to give you the best chance of removing the card without damaging the fixings, which are generally quite brittle, so having replacements available before you start would be a good idea.

Once you have removed the door card, which generally also involves "hidden screws", you should be faced with a clear plastic sheet, or membrane, which prevents moisture seeping into the cabin. You will need to cut carefully into this membrane in such a manner that you can replace it and secure it on completion of the work.

The link below shows the mechanism you will find inside the door carcase and as you will see, there are several pieces that can "go wrong". If you are certain you can hear the motor operating when you make the switch in both directions, then it could be that the motor is "stalling out", which is what it is designed to do at the top and bottom extremities of its travel cycle. If that is the case, then there may be an obstruction to the glass path being caused by something within the mechanism having become detached - which could be obvious. Note if the link doesn't work correctly, you can search for "Jaguar Classic Parts" and simply follow the instructions to reach the information for the XF.

Until you get into the door carcase, it is not possible to say what else you may find. If you are not comfortable accessing the inside of the door on your own, then a friendly body shop may be a good call to talk to.

Many thanks for your advice. Will follow it and report results. At 80 I am reluctant to travel to our nearest Jaguar repair garage, so as a retired C.Eng. I will have another go as I can't leave the car in any public place. Have temporarily covered the window with a plastic sheet but can only use lock without alarm
