My back windows don't work properly; right one go's down slow and the left one opens only half way.
My question is how do I safely remove the back panels, tried it ones with bad result; broke the clips of the b-pillar panel and could not get the panel itself nicely back in place.

Before starting on this adventure, any tips to do it the right way.
