200 CLK 320 top will not go down




When lamp flashes at 3 Hz (3 times/second) while the switch is held pressed, the power roof will not operate, because the controller has not received the necessary electrical signals, confirming that:
1. The trunk is closed and locked
or
2. The retractable luggage cover partition is not pulled out into its fully closed position
A couple of troubleshooting suggestions:
Whenever, the trunk is unlocked, the lamp in center console trunk release switch will remain lit. Check that the trunk release lamp is not lit, while attempting to operate the power roof.
Make sure that the retractable luggage partition has been pulled out into its fully closed position and engages the position/limit switch, that tells the controller that the cover is closed. The switch is located on the passenger side and may not engage if the partition comes off it's guide rails.
