Did the C/C work previously and just quit? Or was it cutting out beforehand?
Buy a Bentley Repair manual if you intend to DIY. (aka, welcome to your new mistress)
Have a butcher's at the cruise control cable. Is it still routed correctly? Are any of the plastic anchors for the cable broken? Does the linkage at the throttle body work smoothly by hand with no binding, stiffness?
Check the related fuses. Do you have an illuminated brake lite warning on your instrument panel? Even tho the brake lites work?...then replace the brake switch that abuts the flange of the brake pedal .
you'll need to remove the knee bar and the lower cardboard barrier.
I you are of good size, the drivers seat will have to come out. I recommend that you have a repair manual handy.
Easy job but very fiddly.

If your speedometer is not working, the CC will not work either. There is a single yellow/blue wire in the cluster harness that splits off and plugs into the green plug on the rear of the speedometer. Without that connection, CC will not work.Owner - Bavarian Restoration
