Power windows sneak down

[9C1pack]

Hi, A friend has an annoying problem with his VY/YZ front electric window sneaking down a few mm while driving, he constantly has to close it.
Is there a known issue with this, can you tighten something up that will prevent it sneaking down?

Never had the issue with mine mate.. may be a wire?? stuck on or something??? a sticky switch??
