..97 SL500 stored winters resulting run down battery. The red button kept flashing and the soft top and roll bar would neither go down or up. Dealership diagnosed a bad control module and supposedly replaced it. I say "supposedly" because the mfg date on the "replacement" control module was circa build date for the car. I should have spoken up and had them try clearing the bad code(s) on the module instead of suspect replacement. My recommendation to you at my expense - clear the codes. If there truely is a problem - they should trip again. BTW, I suspect the main cause of this a rundown battery unable to power top and rollbar, among other things. You could also try replacing battery. Good luck!

(edited) BTW the cost of module was $1100.
