CRUISE CONTROL STOPPED ENGAGING

Many times a bad brake light switch will prevent the cruise from engaging. But your best bet is to get a shop manual and follow the step by step tests. Check with your local library to see if they have online access to a repair manual

Catherine, Check your cruise control fuse as a first step. Could be a bad brake switch, faulty vacuum line, faulty multi function switch,etc., may have to have a good Tech. diagnose and estimate repair.

Try checking the small switch at the top of the brake pedal. There may be two one for brake lights and one for the cruise control. To ascertain what is what, pull one wire off and see if brake lights work. If not, then the other switch controls the cruise control disconnect and engage..I you have a DC test light check to see if power is on on both side of the switch with brake pedal up. If so, depress pedal and check power on the other side there should be none, if there is the switch is defective.

Your best bet is to check what is happening by looking at cruise control data in the PCM and BCM. You will need a high end scan tool to do this. It could be as simple as a bad switch in the steering wheel or a brake switch that is bad or out of adjustment..

Its the brake system.
The flashing light tells you something is wrong with the cruise components. Could be the brake light switch, or the ABS if equipped.

Cruise controls can cease to engage if the clutch or brake light cruise switch are out of adjustment. If this happens, try placing you foot under the clutch pedal (if equipped) and lift up on it (toward you) and hold it while engaging the cruise. If it now works, it will likely cut out when you remove your foot from under the pedal. Check the brake pedal in an identical fashion. Adjusting the switch at the pedals can often solve he problem. Some vehicles (Honda, Acura, Ford, to name a few) have a plastic insert that mounts in the pedal arm which presses against the switch. These can become brittle and fracture into pieces. My Acura has little pieces of blue plastic on the floorboard around the brake pedal one afternoon and I noticed the cruise didn't work. It was the pieces of the insert that had come to pieces preventing the cruise from coming on. I replaced the insert and no more problem with the cruise.

The cruise control can be disabled for several reasons, one is if the check engine light is on or if the speed sensor is inoperative.

check your fueses first, is the check engine light on, if it is it might give u a code?

I had the same problem. When I tried to engage the cruise control, the cruse control light flashed and the cruise control did not work. I also noticed that this happens more often when the outside temperatures are low (below 5 deg. C). The problem was in the brake switch. The switch is positioned at the brake pedal. On Accord 2003 it can be very easily removed by anti-clockwise rotation of the switch. You can replace the switch with a new one or you can clean the contacts of the old one, since the switch can be dismantled very easily.

Check the speed control deactivation switch on the master cylinder. disconnect and use a jumper wire to connect the wires together. If the cruise works it's the switch.
