Rear electric window

Does anyone else find this window temperamental when shutting. I had the ignition on and tried to close from the rear switch, nothing. So started the engine and used the drivers door switch and initially nothing, but then it worked. This is the second time its happened.

Steve B, thinking there might be a short in your system or possibly a bad connector. I was on the way to check something else in my Marco Puzzle and remembering your above post checked out my rear right window. I use it daily with no problems, I leave it cracked open on hot days, but have only used the driver's door switch. This morning, without the key in the ignition, I climbed in the back and opened and closed it several times from the rear switch without issue. Hopefully the dealer can resolve this before it gets stuck open on you on a wet day.

Thanks, I’ll wait for it to go in for the next service. Sounds like mine has an issue, both front windows are fine

I had the same issue and mentioned it on my first service thinking the fuse had gone (it worked with the rear switch). Turned out it was because I had the child lock on... Have you tried it without?

I'll check but i did get it to work and I didn't (I don't think) press the child lock button, but you never know......

I find the rear windows controls a bit of a faff, cannot really work out if it’s me or the car but I always get them to behave eventually. I partly think it down to the buttons not really correlating with the action so I have been trying to remember up to close and down to open.. and think of them as vertically sliding like the fronts.

Method7, that's exactly my feeling. I don't use the child-lock anyway so was surprised when it was pointed out. And since then, activating/deactivating the lock seems to get the rear window switch to function properly, so I haven't investigated further. The behaviour also seems to relate to the auto-locking mechanism. One day I will look more closely but too busy having a great time in the van to worry about these things...
 
I also have a bit of brain freeze on the action. To my mind, open (outward) would be up on the toggle, but of course that's to close. Also as mentioned the child lock seems to stop it operating entirely.

My "brain freeze" is with the shifter, up to go back, down to go forward? Mercedes are you kidding me? Wish I could change it, after 3 months of driving daily this still freezes my brain.

Ha I think I have that one sorted now but when I drive my wife’s manual Mini I keep putting the wipers on when I want reverse, the clutch is fine, changing gears going forward is fine, just bloody reverse lol.

I have to think about the selector, often get it wrong. My Audi auto is a short lever, push forward for reverse, pull back for forward, button for park, that took some time as well

So a little test today.

Key in, try to close window, no joy (because more than 5 minutes has elapsed with engine off).

Engine started, try to close window, no luck (because the child lock comes on automatically -- probably some setting to turn this off)

Turn off child lock, try to close window, success!

I'm a little confused here...
So, child lock enabled = can't open / close window and child lock disabled = can open / close window. That's surely correct behaviour??

I would assume the child lock should just disable the switches in the rear not the ones on the drivers console - that’s the way my old V280 behaved.

I used the drivers side buttons. That's why I found it odd when the guy at the service mentioned that the lock has to be off to open/close the window. Pretty sure that what he says is "correct" behaviour according to the manual too, even if it doesn't really make a lot of sense.

Anyway, @SteveB, did you manage to solve your problem?

Not had a chance, didn’t make it home from London today, one of many looking for hotels and buying shirts. Hope to get home tomorrow so will give it a go

I just tried the rear windows from the drivers console with the child lock on and the windows open and close in the locked position on our 2018 horizon...
