When I have the cruise control on and make a right hand turn it get's knocked off. Sometimes if I hit a bump in the road it will happen also. I can reset it and it's fine. Never does this with left hand turns. This can happen at any speed. Any idea what I might look for?
 
I'd start with checking the fuse boxes for fuses related to the cruise control , one might be dirty or loose , so take it out clean the legs or pins with fine sandpaper or a wire brush and put it back in.Also there is a ground wire that goes to the cruise control servo unit under the hood , this ground wire could be faulty or have a bad connection , I'd simply run a brand new ground wire to it off the chassis or battery terminal , plus the problem could be in the steering wheel column wiring.

Hope that helps and best of luck.By the way the cruise control servo has steel lines coming off of it that run to the throttle body and that's how you know that's the servo unit.
