Hello, hope I have found the correct forum to post in. Recently purchased a 2001 CLK 230. While driving the Roof operation switch red light came on and then blinked about once per second. When I stopped and restarted it, the same everytime I turn the ignition on and start the engine. The roof will not retract, the windows go down, but when I pull the switch nothing happens, including the headrests at rear not going down. I can move the headrests up and down using the dashboard switch but they do not move when the roof switch is used. Also, the boot will not open with the dashboard switch, or the key fob, but can be opened manually with the key. I am feeling these three things (the roof not retracting, the roof warning light flashing, and the boot not opening) must be connected somehow. I wonder if there is any advice that I could try before embarking on what will doubtless be a very expensive dealership route. Many thanks.
