I have a 98 ML320 with cruise control. Does anyone know if the switch assembly on the column is all one assembly with the wiper switch, signals, and cruise control. I want to get the right replacement part before I take the steering wheel off. Also, I need to replace the drivers seat belt. The winder doesn't work anymore. Does anyone know if I can get the passenger side can be used? Lots of used passenger side seat belts out there. I only know about my C230 coupe. This SUV is all new to me. Thanks is advance for your help and advice.
