Cruise works initially, but, when disengaged as a result of brakes being applied or manually disengaged, it will not re-engage when pressing "Resume" or "Set". The problem was intermittent and would return to operational if turned off for a while, however it has since failed to engage at all. Brake switch seems to work OK according to the lights. Is it possible that the problem lies in the switch(es) located in the steering wheel? I've searched the cruise control threads for answers, but was unsuccessful finding a possible solution.
