Summer Opening Windows/Sunroof features doesn't work
I just found out that my summer features to open/close windows using SmartKey doesn't work. What did I do wrong?
1. I have tried as instructed in the manual. To open: Unlock the car, press and hold unlock button, then Windows/Sunroof should open and vice versa (to close)
2. My car is 2004 W211 with Appearance and Premium. Anything else that I have to order? No keyless go. I'm not sure, but I remembered my C-Class has small square black box in the doors' grips/handle. This new car doesn't have. Is this the one that causing problem?
Please help.
