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.

Where is the cruise control fuse located on 2005 chev trailblazer


I take it that it's not working? 1 thing to keep in mind...if there are any check engine codes stored in the computer, te cruise control will be disabled. When this code is cleared out, the cruise control will work again.

There's two fuse:
1. Fuse#4 (10amp) fuse box on top driver feet behind trim cover.

If you're having problem with cruise control and horn act funny at time. You might have a bad cable reel. located in steering wheel.

Cruise control not working on 2003 honda pilot


First thing would be to check the fuse. If the fuse is good, use a vacuum pressure tester and test the control unit. It wouldn't be a bad idea to test the power to the cruise control unit as well.

Cruise control in my 2003 mr2 spyder suddenly went out


check the fuse for the cruise control from the driver side located on the left side of the dashborad. Make sure the fuse is not blown out.
If it bad, change it out but make sure it is the same rated fuse.

Good luck

Cruise control will not come on.


First I would try and replace the #1 fuse which is a 10 amp fuse that powers the Transmission Controller, Gauges and Autostick. If that fuse is good let me know.
