2005 Chev Impala Cruise control stopped working

The car runs fine except the cruise control doesn't engage or work. Is this a module I can replace or something more involved? If it is a module, where can I get the part number and about how much should it cost?

    I have a 2005. My cruise only works if it is turned off before I start the car, then only if I turn it off everytime I hit the brake to disengage it; if I leave it turned on for more than a few minutes, it won't work. I have to stop, kill the car, turn it off, then restart the car. I figure it must be a defctive module, wherever it is; I have only owned the car for a couple of months.

SOURCE: Cruise control stopped working

if the fuses are ok then i would say that there is a distruption between the cruise module vehicle speed sensor and the computer(ECM). unfortunately this is something only a qualified tech with diagnostic equipment can correct. i'm sure there are stored fault codes that the tech needs to check and reset. it's been my experience that oftyen times when this problem happens it has to do with the transmission control module which dictates how the engine and the transmission sync up to shift properly and your speed is measured through the transmission circuit thus the cruise control circuit is slaved to that.anymore questions feel free to contact me . just click my user tab on this site

SOURCE: 2004 acura Tl cruise control wont engage

This is a problem you will to take to a shop, If you are mechanically inclined I can help you, but if not I would not mess with it, it could be the button or it could be the controller and could even just be a fuse, check the fuse and if you don't find the fuse blown then let me know if you have a volt meter and what to test this yourself. You are going to be working around the air bag too and if you probe the wrong wire while testing you could break your arm or leg by deploying the air bag by accident. Or your neck.

2004 Trailblazer cruise control stopped working, all signal lights are functional, and the SES is not on.

Crank & cam sensors would not have anything to do with it . Now if the vehicle didn't run (no spark or fuel injector pulse ) sure. The vehicle does start an run , Right ?

Cruise Control Description and Operation (4.2L)
Cruise Control Description and Operation (5.3L)

Your vehicle has electronic throttle control (drive by wire ) do you know what this is. Complex electronic's invloved . 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.

The PCM will engage and adjust vehicle speed based on the information received from the TAC module via the UART serial data link. For further information on the TAC system, refer to Throttle Actuator Control (TAC) System Description in Engine Controls - 4.8L, 5.3L, and 6.0L.

Your best bet , take your vehicle to a qualified repair shop that has the knowledge an diagnostic scanner to trouble shoot your problem .

2005 Impala cruise won't hold speed. The cruise seems to work kind of.

Check the linkage at the advance to se if it is broken. Some are by mechanical connection and others are by vacuum. If vacuum you have developed a leak and must replace the controler to make it work again.

Cruise control not working in my 2009 Silverado. It went out gradually over the past several months, pretty much worked intermittantly.

cruise control module has failed. or if your brake lights are staying on, then brake light switch has failed and not allowing cruise to engage. Have someone stand behind truck and see if brakes are working properly, if not- replace brake light switch. if fine, then swap out cruise control module under hood.... prob find one at a junk yard.

2005 Chevy trailblazer ext problems 1. Cruise will not set.worked last on 4/12/15 2. While checking fuses for CC problemdome lights stopped working, but worked fine before checking fuses. PLEASE HELP!

Bummer deal! This may be a way to tell you some tail lights are burnt out. Some cruise controls have a fuse in a second location.
The fuse is not in right or is blown. Check with a new fuse. Hope this helps. ...gc

Cruise control on 03 buick rendezvous won't engage, no light, replaced cruise control module?

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..

2005 Chrysler town&country cruise control stopped working

Does the cruise control lights come on when you select it? If it doesn't then you may want to check the fuse(s) that give the system power. If the fuse is blown then try replacing it. If it blows again when you try to use the cruise control then the unit it self may be bad and need replacing. You can find the fuse box location and the right fuse for it in the owners manual of the car.

I have 98 Saturn sl2. The cruise control works intermittently. I set the cruise and it will engage for about 20 to 30 seconds before disengaging. Sometimes it won't engage at all unless I repeatedly...

Testing the electrical inputs to the control module from the switch . Testing power an ground circuits to the switch . As a professional technician this is how i go about find what is wrong ! Not just replacing parts , that gets expensive. Do you know what a wiring diagram is ,an how to use one to pin point areas to do testing ? Here is a site for free wiring diagrams . Enter your vehicle info. Year , make , model and engine size . Then under system click on Engine , then under subsystem click on speed controls . Click the search button , then on the blue link . You will see all the componets an wiring for the system . Do you know how to use a volt meter ?

How to fix cruise control

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.

Cruise control not engaging

Hi there,

As you have not stated the Model of Chev, nor the Year of Manufacture, I will give you some general possibilities:

* Blown fuse
* Short or open in Cruise Control circuit
* Faulty brake switch
* Leaking vaccuum circuit
* Faulty cruise control switch
* Faulty stepper motor
* Faulty transducer
* Faulty speed sensor
* Faulty cruise control module

As with all electrical circuits, you should first check the FUSE.

However, from experience, the most common cause of inoperative Cruise control are:

Brake pedal switch: check that tail lights illuminate when depressing the brake pedal. If not, then replace the brake pedal switch (located up on the brake pedal assembly).

Brake pressure switch: depending on which model Chev you have, there is an electrical switch (look for wires) screwed into the brake cylinder (attached to the brake booster). This switch is a cruise system backup from the pedal switch and measures brake fluid pressure, to disengage the cruise control. When this switch fails, the Cruise Control will not engage. If you have a multimetre, you can test the resistance on the switch terminals (ask Chev for the correct resistance spec) - if not to specification, then replace the switch.

Cruise control release valve: this is the alternative to the brake pressure switch and is also mounted on the brake pedal, above the brake switch. This switch is designed to disengage the cruise control, just like the pressure switch. If you have a multimetre, you can test the spec of this switch (ask Chev for the correct test procedure & specs) - if not to specification, then replace the switch.

NOTE: depending on the year of your vehicle, your local Chev Dealership will be able extract the Cruise Control fault codes, stored in the Cruise Control Computer. This is always the fastest (and cheapest) way to identify the suspected component and will eliminate unnecessary "trial and error" labor costs. This test cannot be done by your typical garage and must be entrusted to your Chev approved service agent only, who will have the correct Scan Tool.
