This is once again pertaining to my on again off again non functionig cruise control. It has been working as often as not of late, until I have to tap the brakes to shut it off. Then it seems to stop working for a while. So my question is where and how do I test the brake switch on the cruise to see if that is what is causing the problem? When I first got the car 3 1/2 years ago the cruise was inactive for a while due to a short in the brakes somewhere. This time it is intermittent. Any Help will be appreciated.

Wheel speed sensor maybe man..

To answer your question, test the violet wire coming off of the brake switch for +12 volts when the brake is NOT depressed. This switch is an input to the PCM for cruise control and opens whenever the brake pedal is depressed.
