Hello Boys and Girls,
I have a new problem today; I know this may have been covered in the past, but I could not find any threads with solution to my situation.
So I have a 2010 XKR convertible that I have owned for just a few months and I have had the wonderful experience of learn about low power issues and am on my second battery (first was a wet and I change it out for a AGM) So I had a instance where the rear window would not go up after a low battery problem but after changing and do a widow reset ( up and down 3 times that I found here on the forum ) it fixed the problem. the next time it happened I did a hard reset disconnecting the battery and touching the battery cable together and this worked. Now I was messing around trying to get the oil light rest and had the ignition on that killed my battery and now my rear window will not work again. I pugged in my OBD2 tester, and it showed a number of faults.
on the BCM so I cleared them, and this did not help, I then did the battery cable reset and that did not help and then tried putting the front windows up and down 3 times that did not help.
I was wondering how common this is and what I need to check from here.
does anyone have any ideas for me, I really want to get this fixed without taking it to the dreaded black hole I call the dealership.

Cheers
Matt

 

I'm watching this thread; it's the stuff of nightmares for a car like mine which currently has to live outside.

 

You did this as in the window reset procedure, correct?
No messages on the dash?
Will the top fully open and close?
Smells like a weak battery. Fully charge it with a charger (not a maintainer).

 

I am not completely sure of the proper way to do a widow reset but I put the front widow up and down 3 time after connecting the battery.
This is a new battery completely charge before install. It is not the battery.

 

Hold the window up/down button longer than the window fully closing/opening, until you hear a click. Do this for both the driver and passenger side, repeat a couple times. If you don’t hear a click, just continue holding that position for several seconds.

 

The window reset procedure of three times up and down only resets the front windows, has nothing to do with the rears.

If you cycle the top several times, the windows should start working again if the top completes it's cycles.

 

WRONG. That's totally related to the rear windows. I experienced it a few time...

 

I retired two years ago after 35 years as a Jaguar Tech, and I doubt that I am wrong.
The up/down rest procedure only works on the front windows to set memory positions.
The rear windows do not have a memory position, they are synced with the top position and latches.

Also, doing the window and top reset procedures is best done with the engine running.

 

Not later than last week I made a hard reset .
I forgot and left for a ride.
Parking for shopping I noticed the rear windows weren't shutting while the hood finished closing...
I made the window reset and getting back to the hood button... they closed.

2 weeks ago , exact same thing.
Beside these 2 occasions, it never happened again and I used the hood at least 25 times since then...

Is this a coincidence?

 

Please show me anywhere in the owner's manual or the Shop Manual that references the quarter windows being reset by resetting the front windows.

 

Maybe nothing 'resets' the rear windows, but they won't operate at all unless the fronts are calibrated properly? Like a safety measure to avoid damage?

 

Yes, after a battery disconnect, you should definitely re set front windows first.
The quarter windows don't have a memory position built into the Motors. Their positioning is set by moving
adjusters on the window regulator.
Resetting the front windows has no direct effect on position or activation of quarter windows. That's controlled by the top latches and positions.

 

I just did as I've read somewhere on this forum from the "specialist about everything window and hood" member...And it worked.
That's all I can say.
PS: as far as I know the manuals are nowhere explaining how to change the tiny rubber button on the door handles....but it sometime get worn out... and has to be changed..and can be changed...Jaguar says you have to change the whole door handle...
So , you see, they aren't saying everything.

 

So how do you explain what i've been through with them?
Do you have a convertible too? did it never happen to you?
Why doesn't it work before reseting the windows? why does it work after?

 

Yes, I've had two convertables a 2000 and a 2006.
I have no idea about YOUR car as I haven't seen it.
When you press Top up, the conv top system looks to see that the front windows have dropped or are already down.
The top goes up, the top latches and sends a signal to the top control system.
The control system raises the quarter windows all the way to their closed rest position.
The control system raises the front windows.

I've worked at Jaguar Dealers and independents for 35 years and have seen just about every problem.

 

That's exactly were it goes wrong.
The front windows goes up straight without the rear one doing it. And that's all.
Weirdly if i reset the windows with the right procedure, then the rear windows goes up.
( once again the problem happened only 2 times after I made a hard reset and used the car as usual right after )

 

We respect your work history, but since you reside in the US, your 2000 and 2006 would be X100 models. Our collective experience with the X150’s is that the rear quarter windows will not rise without having reset the front windows.

 

I have been trying to find this on the manual, but I have a PDF version that I cannot do a search and it pain staking to go through it all to find this.
If I do find anything I will post an update and let everyone know what I find out.

 

And what exactly was the "right procedure" you used? when you put the from windows up and down do you click the buttons all the way and use express up and down or just clicked them halfway? And how many times?

 

Just in passing - it's unclear to me why the hood control 'needs' the front windows to fully open in order for the hood to close. it is what it is I suppose but it's boring to have to watch the front windows open all the way, then watch the hood close, then watch the front windows close again. I always wonder why the hood can't just close with the front windows closed. Is it something to do with lining up the rubber seals?
