After reading several posts, I am not sure where to start to diagnose this.
Thank You,

Definitely check the pedal switches first, but I'm guessing the problem is either a vacuum leak, or a dirty residue on the copper contacts of the switches on the directional arm. This residue also affects the power window switches, and the fan speed selector switch for the heat/AC. Sometimes you can disassemble, clean and lube, and reassemble with success. Other times component replacement is the only way.

The vacuum leak can be resolved by checking the lines as per the book. Leaks along the manifold can be diagnosed with a vacuum gauge and an oil can. Connect the gauge to a vacuum nipple, and squirt oil slowly along the intake manifold gasket edge. If the gauge jumps, the oil has briefly "sealed" the leak, and you have found your problem.

Good hunting!

VW had a lot of trouble with the brake (light) switch that interacts with the brake pedal...it's on the bracket just under your dash. If it's faulty (ON all the time) then the cruise-control won't work. Of course, your brake lights should be staying ON all the time too...
The linkage for the cruise control has some small plastic knuckles on it...they have been known to break...disconnecting the linkage from what its' supposed to be controlling. Not expensive or hard to replace, if you are able to identify the parts under the hood...On the 95 Cab, they are pretty obvious. Well, almost obvious. I had to deal with this about 4 years ago...

I have my own cruise problems, but after speaking with Art, I learned I have a VW aftermarket system in my car.
An electric/non-vacuum style.

Before I found that out, I was digging through some postings looking for help and found that some people fixed their cruise problems. The most common faults I remember reading were:

* The switches involved with the pedals, Brake (and clutch if equipped)
  • Battery acid corroded vacuum line found somewhere behind the battery.

Good luck.
