Check your brake lights. Sounds like you have a bad brake light switch.

When cruse is set, why does it not hold going down hill


Cruise control only maintains speed by utilizing the accelerator. To speed up it increases it and during slowing is removes it. The cruise control will not apply brakes in the event of a steep downhill run. In this case the vehicle will start to accelerate in the same manner as if the cruise control was not engaged. But in theses cases, most cruise controls, once the speed exceeds a certain amount above the set speed, will auto-disengage as a safety feature.

Intermittent Cruise Control Issue - cuts out when small bump in road is hit and may or may not re-engage after that.


Check the wire connector that plugs into the cruise control under the hood. Sounds like a loose connection. Remove the and reinsert the wire connector several times to make a better connection. Stepping on the brake pedal disengages the cruise control by a switch on the brake pedal, not the computer.

Vauxhall vectra sli cruise controll not working


The cruise control is normal disengaged by applying a little pressure to either the clutch or brake pedal. There are switches/sensors on the top of these pedals near the return springs. The retuns springs become weaker with time/use, so it is possible that they are not fully returning to allow disengage to reset so that it can be used again.
That is the cheapest fix and should be the first check.
The next is to cange the stalk as the switch at the end may be broken. Costwise it is relatively inexpensive for a replacement and to instal yourself. Make sure you've done the first part, or else you'll waste money and time.
Good luck.

My 2002 Ford Focus brake lights stay on in drive, cruise control doesnt work and the hatch button in car doesnt work. I noticed the middle rear brake light is also out.


If you brake lights stay on and the cruise control doesn't work then I would be looking at the brake light switch at the top of the brake pedal as if there is power passing through it then it cuts out the cruise control. The same as if you put your foot on the brake cuts out the cruise control. The hatch button will be another problem like a fuse or broken cable or failed latch solenoid. As to the rear middle brake light try checking the bulb first.

My 2007 saturn sky brake lights stay on and cruise doesnt work


The brake light switch, located on the brake padal assembly, is and input to the cruise control module. When the switch fails keeping the lights on is makes the cruise control module think you are applying the brakes when infact you are not. Chek the switch wiring for damage and if ok replace the switch making sure you adjust it properly.

My all wheel drive subaru is now a fwd only. cruise control quit working I pulled the cruise fuse put it back in. the cruise and awd drive worked for about ten minutes then stopped working again. I am at...


Check that the cruise control module fuses are not blown in the fuse panel. Also make sure your stop lights are working; cruise controls are designed to disengage when the brakes are applied, and one method of sensing that is to monitor brake light current.


then reset your four wheel drive again

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.

Ive replaced the brake lite switch twice on my 1996 grand chrokee -when the cruse control is on it will only engadge if i lift up on the brake pedel-but soon as the pegel drops it turns off the cruse...


the brake light switch is part of your cruise control circuit. check the adjustment. it should be threaded so that you can change the depth on it. probably not your switch at all.
