I recently came across the issue of my windows not closing fully, or reaching full height, in my 2005 Lotus Elise 111R. The windows would then leak in the rain or when I would wash the car. The gap became enough that you could fit all of your fingers through the open space and I looked online for a solution. This fix surprisingly was not highlighted in any of the forum posts besides one where it was buried at the bottom, so I thought I should make a quick video about it. If you have this problem I hope this video helps.
Cheers!
