Window and Sunroof auto open/close

[JonnyCJ]

The auto close function on my CL has stopped working. Not sure if it auto opens or not. This happened soon after I had the battery disconnected and the very next time I tried it. In addition the auto open/close on the boot doesn't work, although the motor can be powered independently which operates the open/close facility.

Would disconnecting upset the car's electronics and the PSE system ? A bit in the dark and don't want to go to Merc yet in case it's just a simple reset job, similar to the windows and sunroof (hold the button down for a couple of seconds)

Any help gratefully received !

Cheers

I would say ... reset all the windows including the sunroof ...

open all the windows one by one and then close them one by one ... and hold the button of each window for 5 secs

Do a full open and close on the sunroof as well ... both ways slide all the way in and up.

Similar happened to me when the bodyshop disconnected the battery and I had to do what I mentioned.

You need to 'normalise' the windows.
Simply wind windows all the way down and keep holding the switch in that position for 5 seconds.
Then back up and hold again... repeat for all windows and sunroof.

Can't help with the boot issue though.

edit: DO'H greekcl beat me to it.

Good news on the sunroof and windows - it worked ! boot still an issue though. Looks like a trip to Merc is in order.

mine doesn't work either.

Did you do the following:

All windows up, then put a windows down one at a time and when each window was down keep holding the button down for 5 sec? (the window button and not the remote button)....

Your boot doesn't work ? I put all my windows down and sunroof open, then closed one by one and held the switch for 5 seconds on each. That cured the total closure on the key fob issue.

Boot still won't open/close though...

yes mate, as your original post. I have just tried the above with no look so no summer opening and the boot is playing up to..... also to top it off when I went to try the windows the cd changer wasn't found. The fun of owning a CL

what was it stolen or ran away with the lack of power?

Sounds like something to do with the PSE unit, whatever that is. Hopefully Ollie or someone will come to the rescue ! I've put a post on the "other" forum, so will let you know if I hear anything.

Try the following with the boot ...
open it from the driver door and close it using the soft close...

then open using the normal button above the number plate and close it with soft close...

and check again to see if the key works ?

ooohh if you have the auto open close ....boot is should be just the same with the sunroof... mechanish ... it just needs to be opened all the way and closed all the way , this should do it

Hmm - tried that. The boot will only open if you physically lift it as the various buttons are operated. The pump won't work it. Had the g/f out in her dressing gown and face cream doing the driver's door switch Tried a manual lift and soft close using both methods but key still didn't work, neither did the door switch or boot switch.

Try the following - switch the ignition on then hold down the boot opening switch for 20 seconds. Apparently works on an S500. Going to try mine right now !

Didn't work :-(

Had the car on a Star machine at the weekend and it shows the boot auto open/close as "not normalized" Going to book it in for a full check over as they say it could be something called a hall switch (may have heard incorrectly !) which senses the position of the boot lid. they have them on electric windows as well apparently.

Hooray !!

Sorted at last

Turned out to be a broken wire on the springy mechanism under the rear parcel shelf. This should be the first place to check (prob best to get an auto electrician to do it) as it means that the PSE unit goes into an error mode and needs to be "normalized" by someone with a STAR machine.

If you fix the wire without normalizing the auto open close function still won't work until it's normalized.
