SOURCE: cruise control does not activate

I had the same problem and it's the electronic speed control modual on the fire wall. Just follow the thortle cable to the speed control behind the break booster. I did the junk yard special when i got the price at the dealer.

SOURCE: 1990 GMC Sierra 1500 pickup. Windshield wipers, Cruise Control

May want to look at replacing the wiper circuit board.It is located on the firewall adjacent to the wiper motor and has a some what square black cover with 3 torx screws and wireing harness pluged into the side.We had a truck that every time you washed it the wipers would stay on until it dryed out.You can try removing it and spaying it down with contact cleaner just watch the brease on the two contact tips.Well hope this helps.

SOURCE: I own a 2005 GMC Canyon Five CYL and the cruise

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.

Most times when this happens with Envoys and Trailblazers, your PCM or computer is storing a check engine code, which will disable cruise control. Scan your vehicle with an OBDII scanner to see what code may be stored. Once the code is cleared, your cruise control will work again.

Engine reduced power


Reduced power can be a multitude of things. Find out what code is present by using a scanner. The cruise control WILL NOT work if the check engine light is on. Once the check engine light is cleared, the cruise control will work again.

Click on the link, part of cruise control circuit, you can see the fuses. Not only check the fuses, use a test lite to check voltage on fuse circuit, goes hot with key on.
Make sure the brake lites work?
Check applicable trouble codes relating to cruise control. There are other possible issues.

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.

Looked for 2004 Envoy Cruise Control fuse under hood. Nothing on the diagram says Cruise Control. Which fuse would it be? Number?


There are four fuses that can affect the cruise control. In the underhood fuse panel, fuses #12 & 22, and in the rear fuse panel, fuses #34 & 39.
There are other things that can stop the CC from working, stuck brake light switch, bad vehicle speed sensor, certain fault codes set by the computer, to name a few.
