Wabbly window help

I have just wound my window down on my cabriolet and on winding it back up it’s become very wabbly and doesn’t line up well any ideas why
I have recorded a video of the play but can’t seem to add it on

Cleaning up the mechanism, and greasing things a wee bit always helps on these guy's rolling up or down.

The Rubber tracks can get dirty, as well as bind the glass.

Ah ok I’ll give  that a go it feels really loose going down and tight going up would that be expected

The weight of the glass is assisting you going down.
Where as you are taking the weight of the glass going up When the spring on the winding mech gets full of crud, it can bind….



Oh and be warned, most bolts and nuts holding the rails are an adjustment of one way or the other….

Watch the movement of the glass as it winds down and up it shoudl come up and down parallel and not dip one way or the other, the sad part is that the nylon bits are hard to find, if they are worn, but a good cleaning of the mech can solve a few issues.  I have also found that a Dosing syringe for the kiddies, when filled with a good Axle Grease (I use Marine Grade on my cabbies as it is more water resilient) can shoot tiny bits of grease in really tight areas and limits the amount that I get it places I don't want.
 

 Oils be it’s a rotten clamp and bottom guide.
It’s common for them to rust away
Case of take door cars off and have a nosey.
