I have a 2003 Grand Caravan with a 3.3.
The Cruise works fine, except when coming to a hill.
The cruise does not accelerate to overcome the steeper grade, it just loses speed.
Any ideas?
Thanks

Vehicle Issue Vehicle will not hold set speed | Replace the Speed Control Servo;Verify vehicle complaint. If the vehicle is not holding set speed, you must determine if it is dropping vacuum supply. "TEE" in an in line vacuum gauge between the servo and vacuum supply. If it is a steady vacuum, then check to be sure that the PCM is not getting any signals from the switches for a "coast" request. If no stray inputs are coming from the switches, use a mighty vac tester and pump up the servo to see if it holds vacuum . If it does not, review the below recommendation.
Recommendation Replace the Speed Control Servo.

 

Thank you, I'll check it out tomorrow.

Hello,
My '05 Caravan cruise control is not functioning. When I activate the system, the yellow icon on the control illuminates, but when I hit the set switch on the steering wheel, nothing happens. I did not find a fuse or relay in the manual, so I'm stumped. Any suggestions?
