Cruise Control 380 SL

My cruise control will accelerate my 1982 380 SL but will not hold at set speed. Could this be something as minor as the switch on the steering column or should I look for something else and if so what? Thanks to all in advance.

You need to have the cruise control tested with the correct test equipment or you'll just be replacing parts.

Bobby,

There is a site that has been posted serveral time which has the how-to for testing purposes. Basically helps you narrow it down without expensive equipment, but I can't recall the site right now.

If it accelerates with the stalk, but won't hold, the common fault is in the cruise amp. A couple choices here - open it up and resolder every joint in the amp (about 300 or so it seems), send off the cruise amp for a reman replacement (as long as the old one hasn't been opened up and DIY fixed), or what I did... go to a salvage yard and pull about 5 cruise amps from junkers and keep swapping amps until the dang thing works.

But before doing all that, I would do a search on cruise amps, try to find the mentioned site and test the switch and acuator before yanking the amp.

Never mind the search Bobby, just looked in my history and found the link to GDL .

Hope this helps.

Mike,

Man you are full of info. Thanks very much. Why would I need a CD or a manual when I have this site and you. Trust all is well with you and family.
