Cruise control blinks

Cadillac has a cruise control system that becomes disabled when there is a fault in either the suspension, abs, traction control, or engine management system. The car needs to be scanned to find the cause

Check your cruise control fuse.

have a look at the cruise control cable that goes next to your throttle cable next to your throttle body for looseness

The adjustment of the brake light switch or it could be bad. the brake lights can work fine and the part of the switch that works the cruise doesn't The swiches that control it from the steering wheel can losse connection in a part called the clock spring. Vacume connections can effect the cruise but yours is likly cables less therefore doesn't work the cruize.

cruise control best let garage check out,here are few things to check,check fuse and check to see if brake lights dont work.check brake light fuse if fuse okay brake light switch could faulty or bad connection then brake light will reset cruise control you apply brakes.if all is good problem could be speed sensor or accelerator pedal to ecm.you need diagnostic euipment to troubleshoot.

Typical reason for no cruise and horn is a bad clock spring underneath the airbag. Typically you have an airbag light on as well and not an abs light

are you going uphill in overdrive gear . If the speed is lower than you set the crruise control might disengage. ?

the remote start and cruise control will not work if the codes are stored just because the light is off doesn't mean the codes are cleared

jnjkingbird, It sounds like this problem is the clock spring as I don't believe that the horn and the cruise control would share a fuse. However, they do share a circuit in the clock-spring. You can check for power at each unit (horn and the cruise control) which would confirm this. Check each fuse as well. Good luck with this.
