Hi Keith from LaPlata, MD. I bought a 1998 SLK 230 over the winter and did nothing with it until the weather improved. It appears that the retractable roof will not open and the button flashes when activated. Now when I attempt to utilize the button to close the roof you can hear the motor run and roof attempt to close as it is supposed to. No idea what the problem could be. Now I will note that the drivers side window appears to be off track and does not operate properly when opening and closing. Would this have any bearing on roof operation?
