2003 dodge stratus cruise control not engaging

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.

first check to see if brake lights work, because brake light switch will deactivate cruis control when you press brake pedal to slow down stop.if brake light switch okay, dealership has to check out cruise control since pcm and vechicle speed sensor control the cruise control also.

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.

P0582 is the Chrysler Diagnostic Trouble Code (Error Code) for:

Speed control vacuum or vent solenoid circuits open or shorted

If you do not have cruise control on your vehicle, you can ignore this code. If you do, you've probably noticed it is no longer working or only works intermittently. The code is saying it's an electrical problem to the servo.

The most common solution is to replace the brake light switch . The switch has 3 sets of contacts one set is for the cruise control. If the cruise control part is at fault the cruise control will not engage. The switch typically costs from 10 to 15 dollars.

My 2003 Ram 1500, would not engage the cruise control, when the speed sensor on the rear axle, was the problem. The other symptoms, speedometer worked irregularly. Replaced speed sensor on top center of rear axle, and problem went away.
