W124 - HOW-TO - Sunroof Disassembly.

Note this is how to disassemble it out of a junkyard car. This is merely educational so you know how the system works. If you are taking out of your own car, the steps can vary. For example, if the motor in your car works, you don't have to put a drill battery power onto the motor pins to get it to spin, this is simply because the junkyard cars don't have a car battery installed, etc.
