CHEVY CRUISE CONTROL PROBLEMS

2003 Chevrolet Impala

2003 Chevy Impala 6 cyl Front Wheel Drive Automatic 178000 miles

Hello, intermittently my cruise control will disengage as I am driving down the highway with it engaged. When this happens you feel the car gives a little jerk and the dash light goes out for the cruise control. Its seems once this happens it will not work until you turn off the car and try it on the next trip. Also, sometimes when I go to turn on the cruise control it will not engage (no light on the dash board).I would say that the cruise control works about 75% of the time for turn on but fails probably about 30% of the time while it is engaged.

Any ideas on what might be wrong?

Thanks,
Scott

You will need a scan tool to check for trouble codes. The cruise module is loosing a signal from somewhere. Could be a brake switch, set switch ect. A scan tool will show this when it happends
