Cruise control is suppose to cancel when brakes are applied.

Did you try just changing the bulbs?

If its not the bulbs I would have to say check the brake light switch at the pedal, it is a different switch than the cruise control cut out switch.

1975 chevrolet truck. turn signals and stop light not working


Your brake lights go through your turn signal as well, That's what disables a brake light when you use your turn signal, In other words, When you hit your brakes, Your brake lights come on, Then when you use your turn signal, It cancels that brake light on the side that you're turning..Make sure you're getting fire to your turn signal switch and if it's coming through when you apply the brakes or use the signals..

Right turn signal possible short


I think your flasher is working properly if its blinking fast while that light is out. I think you may have a grounding issue with the wires on that light. Unplug it again and look all down the wires to see if there are any cracks or brakes. You can take the bulb out and attach the positive lead to the bulb and ground it to the chassis. It should turn on. If it doesn't then your problem is in the positive lead, if it does turn on your problem is with the ground wire.

Possible causes

The P0573 codes is set when the stop light switch signal is too high.
Possible symptoms

When the brake pedal is depressed, the stop light switch sends a signal to the Engine Control Module (ECM). When the ECM receives this signal, it cancels the cruise control.

2005 chevy trailblazer - no cruise control and brake lights only work when key is turned off


I would check the turn signal switch. The cruise and turn signal are on the same switch. The brake lights go through the switch before going to the brake lights. And the turn signals don't work with the ignition off.

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.

Brake light problems on a 2000 chevy lumina


Will your Center High-Mount Stop Light (CHMSL) illuminate when you depress the brake pedal, but the lower/outer lights will not?
-- Do you have to hold the signal lever in a certain spot to get the turn signals to flash?
-- Do you have to hold the signal lever in a certain spot to get the lower/outer brake lights to illuminate?
-- Will the signals work in one direction, but not the other?
If you answered yes to any of the preceeding questions, your turn signal switch is likely malfunctioning.

**One more question before we continue: Is the turn signal lever not "cancelling" (returning to the "off" position) after you make a turn? If this is the case, you have a broken "cancelling spring."


Before you begin disassembly of your steering column, verify the turn signal flasher is not malfunctioning. If your brake lights work fine, but not the signals (either direction,) then it's likely the flasher is burnt out. The flasher itself is located underneath the dash near where the steering column passes through the firewall

NO BLINKERS WHEN I PUT ON THE BRAKES


Check to see if you have a burnt out light bulb, that usually causes your blinkers to stop working when you apply the brakes. and check your four way flasher fuse, it's part of your turn signals and brake lighting system.
