Looking through the archives, I can't find anything exactly like the problem I'm having with the cruise control.

Sometimes, it simply won't engage. If I stop the car, turn off the key, and re-start, it WILL engage. Then is works fine (mostly, a little more surging lately). It'll work fine for several trips, then it will just refuse to engage, and I have to stop and re-start to get it to work.

Any suggestions, ideas on troubleshooting it?

Thanks,
