after having to boost my 1995 XJR6 due to a flat battery she's developed a few electrical problems drivers window stopped working ,both power seats stopped working all functions also memory settings and mirrors .fuses seem ok any thoughts greatly appreciated.

 

Try disconnecting the battery for a couple hours that is what I do with most cars when they have gremlins it resets all the electronics hopefully you didn't fry anything when you jumped it

 

Thanks for the reply did disconnect battery for a few hours unfortunately no joy, fried looking likely . My electrical knowledge very limited .

 

Dam that could be costly
Funny how its just the things you said if it had fried the car you would have thought it would have fried the lot
Try flipping the fuses around they can sometimes get a bit corroded from being in the same spot for a long time also I had a couple fuses blown that looked fine to the naked eye only reason I found that out was I just replaced all of them on a hunch while you are checking them see if anything smells burned or has a burned smell I wont jump start modern cars unless I have special anti zap jumper leads learned that the hard way years ago on a new ford

 

Finding out the hard way really sucks, will try replacing all fuses, fingers crossed .And have a good go at solving the problem this weekend cheers Doc.....

 

Do this again but try a "hard reset": remove both cables from the battery and then hold them together for a few seconds.

Cheers

Was the vehicle you used for the jump running or not? The jump vehicle must NOT be running, per instructions in the Jag owners manual. Jumping from a running vehicle poses the risk of damage to the Jags electrical system.

 

In addition to doing a 'hard reset' and checking fuses for the non operational accessories as advised in earlier posts, the flat battery has to be suspect and probably contributing to the ongoing problems.

Does the vehicle have an OE Varta battery as fitted by Jaguar to UK vehicles or an aftermarket replacement? If it's a Varta, you can tell the age of it from the code on the negative terminal:



This one is 23-12 indicating it was manufactured Week 23 in Year 2012.

Any battery over five years old is on borrowed time.

cheers guys will try a hard reset, thats a new one for me. unfortunately the jump car was running at the time ops ! The flat battery has been replaced sadly with an after market bosch. Does anyone know if the seats can be adjusted manually, the drivers seat is perfect for me but the passenger seat needs raising for my wife.

 

The seats cannot be adjusted manually but you can power the motors through the appropriate pinouts to the seat module harness.

I think this is the correct circuit diagram for your model:
