I was able to find a replacement CC module for my '93 6.5 C2500, if this is the type of module you have. I think it was a Dorman, but can't find the paperwork on it now. My bad module would not maintain an acceleration for more than a couple seconds and after taking the cover off of it, found that the cable ribbon spool worm and spur gears were bad. The worm gear's center teeth worn out badly. Plastic gears, of course. The reman. module had a bad problem of very abrupt action on reengaging a set speed. Annoying. So, I took the cover with the circuit card off the old module and put it on the reman. module that had the new worm and spur gears. Solved the problem and has worked fine for 5 yrs. now. Lube the new gears with something that's compatible with plastic gears if you do this.
