on my 94 Z-71, the stop lamp switch was bad, on the lower steering column, and this switch is what gives the CC (cruise control) the signal to disengage. So in effect, when you depress the brake pedal, the CC assumes u are slowing down on an incline or some other natural deccelerant, and engages the accelerate function to compensate. check to see that your stop lamps are functioning, if not, this COULD be your problem, or something in this line of the system.

No , absolutely not ( if you hit a puddle , which will slow the car down , the cruise control willtry to accelerate the car to maintain the set speed )It's not recommended to use the cruise control in the rain. Normally, you use the cruise control on the highways. When it's raining you need complete control on the car and be fully alert.( NO ) if you hit a puddle that slows the car down then the cruise control will accelerate the carbetter not it could cause the car to accelerate at the wrong time and cause loss of control

Why won't 2004 accord cruise control set?

Make sure you have the main cruise control button depressed. You will then see a display light indiciating "Cruise Control". After that, just use the normal buttons to set, accelerate, and coast. BEWARE, though. The cruise control button for our 2004 Accord stopped letting me keep it in the depressed position, and I can't keep my cruise control on now. Will let you know once the mechanic takes a look at it.
