SOURCE: Why does'nt the Cruise Control Activate 2007 Chrysler Pacifica

Hi Daniel, I'm glad to help! One of the most found problems with cruise control's inoperative here at the dealership is a vacuum problem. If you do not have vacuum from the engine to the cruise control under the hood, then even though the rest of the system is working fine it will not pull the accelerator pedal. NEXT: Another problem could be that the cruise control unit under the hood is not getting power from the brake switch. Check and see if there is power at the unit's connector under the hood. If there is no power then replace the brake switch. NEXT: The PCM may not be getting a signal to apply the cruise and this mainly happens because of a cruise switch problem OR the signal is not getting through the "Clock Spring". This could be either one causing this problem, so replace the switch first because its cheaper. If all of these things check out good then it could be the Cruise Control Unit itself. Hope this helps and have an awesome day Daniel.

Can the clock spring stop my cruise control from activate, not even the indicator light in cluster .


If the clock spring is defective it can affect the cruise control if the buttons are on the steering wheel. Usually the horn will also be affected as well and the airbag light on constantly

Where is the fuse for cruise control on a 2003 envoy


It is HVAC 1fuse #39 in the rear fuse block ,this powers the on/off switch for cruise control ! Fuse Block - Rear Beneath the left rear seat. What engine does it have ? 4.2 L or 5.3 l There is no vacuum involved in the operation of the cruise control ! Your vehicle has electronic throttle control .
Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at vehicle speeds above 40 km/h (25 mph). Steep grades may cause variations in the selected vehicle speeds.
The following are the main components of the Cruise Control System:
?€¢
The powertrain control module (PCM)


?€¢
The On/Off switch


?€¢
The Resume/Accel switch


?€¢
The Set/Coast switch


?€¢
The TCC brake switch


?€¢
The stop lamp switch


?€¢
The throttle actuator control (TAC) motor


?€¢
The vehicle speed sensor


Cruise Control Engaged
The cruise control system will engage and adjust the vehicle speed based on the activation of the following cruise control switches:
?€¢
On/Off


?€¢
Resume/Accel.


?€¢
Set/Coast

The cruise control switches are located on the multifunction/turn signal lever.
The powertrain control module (PCM) monitors the signal circuits of the cruise control switches in order to determine when to capture and maintain the selected vehicle speed. The PCM uses the throttle actuator control (TAC) module motor in order to control the vehicle speed. For further information on the TAC System, refer to Throttle Actuator Control (TAC) System Description in Engine Controls - 4.2 L.
Ignition positive voltage is supplied from the 10 ampere HVAC 1 fuse to the cruise control switch via the ignition 3 voltage circuit. When the normally open cruise control On/Off switch is turned On, the switch closes and the PCM detects a high signal voltage on the cruise control on switch signal circuit. When the normally open Set/Coast switch is pressed, the switch closes and the PCM detects a high signal voltage on the cruise control set/coast switch signal circuit. To engage the cruise control system, turn the On/Off switch On and momentarily press the Set/Coast switch. The PCM will confirm that the cruise control enable criteria has been achieved. The PCM will engage the cruise control system and record the selected vehicle speed. The PCM sends a class 2 message to the instrument panel cluster in order to illuminate the cruise control indicator. Pressing the accelerator pedal, while the cruise control system is engaged, will allow the driver to override the cruise control system in order to accelerate the vehicle beyond the current set vehicle speed. When the accelerator pedal is released, the vehicle will decelerate and resume the current set vehicle speed. The driver can also override the current set vehicle speed via the Set/Coast switch and the Resume/Accel switch. When the cruise control system is engaged, pressing and holding the Set/Coast switch will allow the vehicle to decelerate from the current set vehicle speed without deactivating the cruise control system. When the Set/Coast switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily pressing the Set/Coast switch will allow the vehicle to decelerate at 1.6 km/h (1 mph) increments for each time that the Set/Coast is momentarily pressed, with a minimum vehicle speed of 37 km/h (23 mph). When the normally open Resume/Accel switch is activated, the switch closes and the PCM detects a high signal voltage on the cruise control resume/accel switch signal circuit. Activating and holding the Resume/Accel switch, when the cruise control system is engaged, will allow the vehicle to accelerate to a greater vehicle speed than the current set vehicle speed. When the Resume/Accel switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily activating the Resume/Accel switch will allow the vehicle to accelerate at 1.6 km/h (1 mph) increments for each time that the Resume/Accel switch is momentarily activated, with the maximum acceleration total of 16 km/h (10 mph) over the current set vehicle speed . Momentarily activating the Resume/Accel switch, after the cruise control system has been disengaged by pressing the brake pedal, will recall the previous set vehicle speed that is recorded in the PCM.

How do you activate the cruise control on a Mercedes ML 270 cdi.


If you know how to set your speed limiter. To set your cruise control, press the stalk in (to the right). The orange light on your dash should go out and you're ready to set your cruise control. You can start the cruise control by either moving the cruise control stalk up or down. Once you start the cruise control you can move the stalk up or down to increase or decrease your cruise speed. You can move it toward you to shut off the cruise control. You can press it in again to go back to the speed limiter. I hope this helps.

Cruise doesn't work. Checked fuse and its good. Does this truck have a self diagnosis or do I need to rely on Chevrolet to fix?


Before you go to the dealer check your stop lights including your cyclopes. Cruise controls use brake lights for resistance to activate cruise.

Parking Brake Light won't turn off, Cruise Control won't engage


Get down and look at parking brake assembly, If you see an electrical connector, unplug it, see if that helps? If it doesn't help or causes other issues just plug it back in.
Of course that isn't the proper fix. If something wrong with parking brake assembly, get it checked out.

Cruise control inop


if the cruise control does not activate. Check the cruise control fuse. Do a visual check of all wiring relating to the cruise control system. Visually inspect the brake (and clutch if so equipped). If these are out of adjustment, the voltage cannot get to the components down stream with enough power to operate the cruise control.
Visually inspect for vacuum leaks in the release hose and valve, If the cruise control system fails to maintain the set speed, check the throttle linkage adjustment.

Cruise control is out on my 09 silverado. small v-6. fuse is good. had throttle body replaced 3 months ago. 126k miles, i drive a lot. tried the top off the master cylinder trick. still won't work....


you could have a problem with the brake switch which de-activates the cruise when you push on the brake or a bad cruise switch or control module.have the cruise system checked out to find what is causing the problem first then go from there.

I own a 2005 GMC Canyon Five CYL and the cruise control stopped working last niight. You push the button and no cruise. I checked the fuse and it is ok I exchanged with another 10AMP and no change still...


Start with the simple and check the fuses and the Stop lamp switch. Check your brake lights, if they're not working, the cruise won't work either. If they're not working, check the fuse for them, if the fuse is fine, then take it into the dealer, there's been a recall issued on the brake switch, so it should get fixed for free.
Cruise Control Disengaged
The powertrain control module (PCM) disengages the cruise control operation based on the signals from the following switches:

* The stop lamp switch
* The TCC brake/cruise release switch
* The clutch release switch, if equipped
* The cruise control On/Off switch

The TCC brake/cruise release switch and the stop lamp switch are mounted on the brake pedal bracket. When the brake pedal is applied, the normally closed TCC brake/cruise release switch opens and the normally open stop lamp switch closes. The PCM detects a low signal voltage on the TCC brake/cruise release switch signal circuit and a high signal voltage on the stop lamp switch signal circuit. When the clutch pedal is applied, the normally closed clutch release switch opens and the PCM detects zero voltage on the CCP switch signal circuit. The vehicle speed stored in the memory of the PCM will be erased when the cruise control On/Off button is turned OFF, or the ignition switch is turned OFF.

The Cruise Control System will disengage when the PCM detects that a driver override function has been active for approximately 60 seconds .

When the Cruise Control System is disengaged, the PCM sends a class 2 message to the instrument panel cluster (IPC) in order to deactivate the cruise control indicator.

Cruise Control Inhibited
The powertrain control module (PCM) inhibits the cruise control operation when any of the following conditions exist:

* A cruise control related DTC has been set.
* The vehicle speed is less than 40.2 km/h (25 mph) .
* The vehicle is in PARK, REVERSE, NEUTRAL, or 1st gear.
* The engine RPM is too low.
* The engine RPM is too high, with fuel cut off.
* The vehicle speed is too high, with fuel cut off.
* The system voltage is not between 9 volts and 16 volts .
* The Traction Control System (TCS) is active for more than 2 seconds .

Thank you for using Fixya and start with replacing the stop lamp switch. Even though the brake light work, it;s been known for that switch to cause your issue. that's way there was a recall for it.
