Got the cover off now? Good. Here's what you are going to see. It turns out the W123 vintage cars have less electronics in the ACC unit and more mechanical stuff. You'll see that in a minute. The parallel rows of pins along the far side of the circuit board represent the pushbutton switch connections (there are more, as we shall see). Now you have the chance to look for cold solder joints and broken solder joints.
