Re: Renault Laguna II - Interiors - Electric Window Problems - Regulator Repairs
The mechanical side of the window winding mechanism suffers from lack of lubricant on the various parts, especially those hidden right up in the top of the door. It eventually busts the wire ropes that move the glass. This needs the whole mechanism replacing. I got a new one from Euro Car parts.
The electronics are sensitive to the load the glass puts on them, so lack of lube might show up as the window stopping, it should sense if its jamming or has a person's hand in the way.
WD40 first, money later.
