Cruise Control

[gjhumphris]

Sorry about all the questions I've been asking over the past 10 days (since I bought my first SVX). I love the car and, although it's in really good condition, I just want to rectify a few things which aren't working properly.

I noticed my Cruise Control is not working. The dash switch and light both come on as they should, the Cruise fuse is good, but nothing on the steering wheel control works (ie I can't set a speed). Is there a common fault with these? I noticed quite a few Cruise spares on ebay, but not being overly mechanically minded, don't know where to start.

Any ideas would be greatly appreciated.
