Car: 95 Mercury Grand Marquis
Issue: Frequent & Intermittent Cruise Control Failure
Specific: Often unable to engage cruise control for more than 1-2 seconds. As soon as "speed control" display comes on, it disappears from the dash board. Sometime it works perfectly for a while, then I disengage due to traffic condition then it won't able to engage again. Cycle the cruise ON-OFF/Set/Resume does not work.
Does anyone have troubleshooting ideas or know what is wrong with the unit?
