Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing more. Check fuse 34 in the fuse box. It's called the smart junction box. It's the fuse for the servo in the engine bay. The servo is very prone to failure. But if the cruise light does not come on the dash it is most likely 1 of 2 issues. 1 the buttons have failed or 2 the clock spring contact behind the steering wheel is not sending the proper signals. Here is the test list.
1. Verify ALL brake lights are functioning and repair as needed.
2. In Antilock Brake System (ABS) DATA, monitor for correct ABS wheel speed input as compared to the Speedometer and Powertrain Control Module (PCM) Vehicle Speed Sensor (VSS) Parameter Identification (PID).
3. Verify battery power is present to the servo on the Light Blue/Pink (LB/PK) wire from fuse 34 (5 amp) of the Smart Junction Box (SJB) and the Tan/Orange (TN/OG) wire from the deactivator switch and fuse 27 (5 amp) of the SJB. Check the Black (BK) wire of the servo connection to verify it is a good ground.
4. Monitor the Speed Control switch input circuit by backprobing the Light Blue/Black (LB/BK) wire at the speed control servo with a DVOM and exercising all the switches. Expected readings Key On Engine Off (KOEO) are as follows: (all readings + or - 0.03 volts).
a) No switches pushed, 8.1 volts.
b) ON switch pushed, battery voltage.
c) Resume, 5.9 volts
d) Set/Accel, 3.7 volts.
e) Coast, 1.1 volts.
f) Off, 0.0 volts.
5. If any individual switch shows an incorrect value, the set of switches is suspect for failure.
6. If all switch readings show an incorrect value, address the circuits, clockspring connection, etc. for an issue.
7. Check the Light Blue/Yellow (LB/YE) wire of the servo to verify it is not showing to be grounded. The Transmission Range (TR) sensor (automatic transmission applications) should ground this circuit when the transmission is in Neutral (only).
8. Monitor the Grey/Black (GY/BK) wire of the servo connection for a square wave signal with changing frequency as vehicle speed changes. This signal is supplied to the servo from the ABS module.
9. If all circuits and signals check to be OK, suspect a faulty speed control servo.
