2nd Gen Non-Engine/Transmission cruise control ramps up

[GMichaels]

Looked through the post on cruise control fixes, checked my vacume lines.



what happens only when cold (35 or less). when I set the cruise the speed will increase, then decrease and the increase etc, each cycle a slight speed increase will occur of about 2 mph. I started at 55 and went up to 65 on its own before I shut it off.



when its warm works fine. Any TS Tips?

My 98 used to work great and then started over shooting real bad when I would set it and it was worse in cold weather. I finally replaced the servo for about $35 from the dealer and this solved the problem. I know there are different problems but this is what fixed mine.
