This is part 2 of a 4 part video series Kent has done on repairing the power tilting sunroofs on the W201 W126 and W124 chassis built from 1986 to 1995. Part 1 covers removal and replacement of the sunroof panel and headliner. Part 3 covers removal and repair of the sunroof motor and cable assembly and Part 4 will cover routine maintenance and adjustment. You will need to remove the panel to work on the tilting arm mechanisms. If you are not familiar with that procedure refer to the factory service manual or watch part 1 of this on demand video series.
Kent is a strong believer in the importance of understanding how a part or mechanism works if you are going to diagnosis a problem and then fix it. He starts the video explaining three different problems he is having on three different models. Next, using a complete sunroof mechanism removed from a car, he walks you through how it works. After watching that you may be surprised that these mechanisms hold up as well as they do. He explains what each mechanical component does and how to remove them all from the car. Then using three different failed mechanisms, he explains the type of problems you may run into with your own power sunroof and how to fix them yourself. Since most of the problems are caused by the lack of proper lubrication he spends considerable time showing how they should be cleaned and lubricated before reinstalling back into the sunroof tracks.
Learning how to fix your own titling sunroof can save you hundreds of dollars! Many owners just let it go but now you can fix it and have a smooth and fully working sunroof again...
