Remove sunroof motor on 1983 Mercedes?

Here is what the shop manual says.

1. Drop the head liner.

2. Disconnect teleflex cable end from sunroof.

3. Press sunroof button to "open" to disengage cable from motor gearbox.

4. Remove cover in trunk on LH side and disconnect motor wires.

5. Disconnect teleflex tube.

6. Remove unit.

If the cable is frozen you have to disassemble the gearbox on the motor assembly.

If the motor is dead you can manually open and close the roof from the motor assembly.

As a side note you may be able to disconnect the teleflex tube at the motor and just run the roof open to disengage the cable from the gearbox. This would keep you from having to remove the head liner. I have not tried this but I would try is first

Hope this helps.
