Re: 98 chevy k1500 cruse control
Appreciate the "Ask Me".
To my knowledge, Cruise Control would be relatively difficult to diagnose without a scan tool attached to the control module to read the error codes. Additionally, car versions in my country seldom have such a device since our roads are narrower and travel distance is not that great.
vacuum line to actuator (most likely), vacuum actuator, diaphragm, control valve.
Other possible components to check are:
the control module itself (bolted to the firewall);
control cable or linkage;
steering wheel controls switches;
throttle position sensor.
As posted above, quite a number of possibilities. Any other indications, speedometer OK; abnormal throttle responses; abnormal idling, brake light always ON, slack in the accelerator/gas pedal? Was it cutting in/out before? Was there any recent repair work done on the engine before the cruise control cut out?
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.

The most common problem on this vehicle is the sensor right on the master brake cylinder the seal goes out and brake fluid gets right in the sensor ruining it that is the most common problem lete no if it helps
It sounds like a connection to your cruise control may have come loose and was not intentionally done by the mechcanic. I would take it back and ask him or her to take a good look again at the work he had performed and maybe it will show up in front of his face plain as day
Need to check the brake light switch. ok down by the brake pedal there is a switch that tells the lights to turn on when you push it. almost always easy to fix and you can buy a switch aftermarket for around $10 bucks. If you have cruse control a good way to check the switch is to run the cruse con and try to get it to stop crusing by pushing the brake pedal if it keeps going thats your problem. hope this helps
I had the same problem with my 2003 santa fe. Do you have any brake lights out in back? Weird as it is, as soon as I fixed a burned out brake bulb, my cruise worked again. The only relation I can think of is that tapping the breaks causes cruise to turn off - so maybe a broken brake/tail light passes a singal to cruise control from some reason???
