New here. This forum looks great by the way.
My C5 2019 Aircross passenger front window bounces back when attempting to close. I've tried resetting the anti-pinch but when I do the long pull on the switch after inching the window closed, it just goes back to partially open.
I've noticed that the trailing edge of the window when fully opened seems higher than the glass on drivers side window when fully opened. It's as if the pax side window glass is slightly out of alignment. This slightly high trailing edge seems to activate the anti pinch. I've tried grasping the glass and trying to "level" it but no detectable movement.
Is this a "thing" and if so, what to do?
Thanks

Re: Window not closing
When you've 'inched' the window up and it gets to the top. Only use the first position on the switch (as in when manually closing and not the one-touch second position). When it closes, again just hold the switch at the first position for a few seconds, again not fully lifting the switch until you hear that slight click.
If it's still playing up, then you've got an alignment issue I suspect that the window mechanism is treating as an obstacle from the resistance and so is releasing as intended.
Short of taking the door card off and all the associated work to get to the window securing clamps to check alignment, I'd get some silicon oil spray (not WD40) and lube the window channels on both sides, raise and lower the windows several times whilst spraying to reduce resistance.

Re: Window not closing
Thanks Marc. I've just now tried this reset multiple times being careful to use only the first position for the long hold. However, no click and no reset. I'll try the silicone spray but to be honest, the window seems to be sliding up and down quite smoothly.

Re: Window not closing
No worries - the oil can reduce the resistance for anti pinch to kick in, so an inexpensive option to try first

Re: Window not closing
I've had a thought that the problem may be related to the window being frozen shut one morning and the motor working overtime and eventually managing.to.shift the window. It will have put a lot.of strain on the mechanism. Maybe this has caused a misalignment. Silicone spray arriving today, so will try next.

Re: Window not closing
Aahhh.... if you'd mentioned that to start with I'd have concurred with that as the factor.
This can also cause the wire to break - water gets in, rusts the regulator wire over time and just when you are at the car park ticket barrier, decides to break!
Frost / Ice freezes around the weather seal and of course, that will strain the motor, but can also force the glass from the holders when lowering the window. So this may indeed be what has happened - so when raising, when it gets to the top, it's trying to force the window bottom back into the glass holder and the anti pinch is kicking in.

Re: Window not closing
Yes, it didn't occur to me to begin with, but reading your reply seems to confirm the cause. Question now, how to fix? Sounds like if I can access the glass holder etc it IS fixable? How to access? Where to start even? Is going to be tricky?

Re: Window not closing
It's not going to be a 5 minute job for sure, because the door card will have to come off, which means removing some trim and window control switches, some screws, unplug the connectors and then you'll have the sealing sheet cover over the door that needs removing.
The glass seems to have 2 shaped areas with holes in the bottom and side grooves, but I don't have the exact method to remove it to be honest. There are 2 side grooves and I thing one or more clips. As I can't see what is inside I can't advise, but will require the window to be moved to get access to the relevant bits.
So unless you can raise the window as high as it will go, then get somebody to hold the panel from both sides and at the same time they apply some upward force, operate the switch to raise the window electronically - which may work, or it's going to be a lot of work just to see how it's all secured.

Re: Window not closing
Could applying downward force to the trailing edge of the window possibly push it back into its "holder"? At present it seems.like.the trailing edge is getting to the top too quickly after the frozen episode. However I'm wary of breaking something and at least for now, after your explanation, I have a way of inching the window closed.

Re: Window not closing
My concern here would be that there is already some force on the window being exerted when it is raised to the top (albeit manually), so this is obviously not 'pushing' it back in place. So it may be that there is some fixing that has broken or it isn't holding the window in place at the bottom holders.
