You should check the brake switch. Is that what you replaced?

Yes, the brake switch was replaced.

Can you pull the OBD codes and post them?

When I turn the car off it resets itself, so I Have to re engaged the cruise control to get the error message. I have a pending code of P1111. The last 6 digits of my VIN is 027727.

Well I took it into the shop. The problem was a Clogged vacuum hose. Fixed - Cruise control working beautifully.:icon_bike:

Good to know but do you know what hose was clogged?

It was a bad vacuum hose under right front inner fender liner for cruise control vacuum tank.
