I recently did a lot of work on the 300 to get it into really solid shape for long-distance cruising, and in doing so I figured I wouldn't have time to deal with the inoperative cruise control system. I decided to just check it out later - i.e. now. However, in dealing with the lubrication and adjustment of the throttle linkage, I found that someone may have removed one or more components of the cruise control. Does anyone have a photograph or clear diagram of the system on a six-cylinder car? I found a number of the same for eight-cylinder models, and the parts I am searching for are not located in the same spot. I would appreciate anything - even just a quick snapshot of someone's engine with the proper cruise system functional. Thanks!

I don't have a picture to show, but I will say the most common reason for inoperative cruise control on these cars is a faulty cruise control amplifier. Just put one in my '91 300se last month, an easy job. Hopefully there aren't missing components on your car. Best wishes-

NKJohn,

Thanks for the kind wishes - I planned to just re-solder the amp connections as per the instructions in the DIY threads, but on examining the throttle linkage, I see nothing other than throttle componentry, NOTHING to suggest cruise control! I have a cruise control stalk, so I just assumed I had cruise control and that it was faulty, but unless the actuator mechanism looks totally foreign to me, I think some joker yanked it!
