Hi,
I have had a V8 convertible for the last 4 years and love it, just joined the group to see if anybody can help with a problem that its developed.
When opening the door (drivers mainly) the window is supposed to drop slightly so that it does not catch on the trim. This has stopped happening (Still works occasionally). Also, not sure if this is related, but when I unlock the doors via the keyfob, the mirrors no longer automatically open either (Again works occasionally).
Had a new battery fitted, but still got the problem.

Anybody got any ideas??

Many Thanks in advance

Phil

Have you done the window reset procedure (I bet not!), Should be described in your manual but basically consists of holding the window switch down for a few seconds after it's reached it's limit, and holding the window switch up for a few seconds after it's fully up.

Can't help with the mirrors, sorry.

Also, is the battery fully charged? New batteries aren't usually supplied fully charged, and low voltage can give rise to all sorts of random failures on these cars.

Have you tried removing positive terminal off battery and leaving for a few seconds, this does a reset
(You'll then need to set up the one touch windows again)

Also, dont some new batteries need coding to car, basically telling the car its a new unit and what state of charge it needs to be at etc (car will work if this hasnt been done, but people report funny elec issues as a result)

Hi Phil,

I had the same problem with my car, and found one other instance on Google (the poster there never came back to say if they rectified it).

Mine went back to the Dealer where it stayed for 5 weeks. Their Master Technician couldn’t fix it, even with the help of Jaguar Technical. I know it had a new Body Control Module, and possibly a door module. I think they had got to the point of a damaged loom, but couldn’t work out where.
They insisted they’d get it fixed “eventually”, but after 5 weeks I lost patience and gave the car back.

I hope you have better luck, and find someone with better fault finding abilities.


Edit - the Dealer managed to partially rectify it, in as much as the window would drop until the car had been left to go to sleep when it failed again. I think the keyless entry had stopped working as well.

Thanks for your replies, yes the new battery had been configured to the car.

Update:
Car been back in the garage this morning and windows have been reset using the plug-in diagnostic machine.
Everything worked fine, until I got home and tried it again......
1) Window does not always drop when you unlock
2) Mirrors do not auto fold out

    Disconnect the +ve from the battery, or 2 +ve's if you have two batteries.

    You forgot the real penultimate stage: "give it a good test".

    Only if the process is done in the morning, not evening :)
