SLK 230 (R170) owner for almost 2 years. Love the ride, made a couple of cosmetic improvements to make ride look newer, snazzy. i joined to get some help with a problem that just cropped up. My Vario Roof will not retract. The trunk opens as it should, then nothing happens. The red light on the console switch flashes fast, so something is not right. Any ideas on trrouble shooting or approx cost to repair? Heck even my side windows are now stop down. Is this a relay problem or hydraulics? Hmm. Help!!!
