Cruise control stopped working i was told it was the brake switched i replaced the brake switch and its still not working any ideas?
I just got the perfect answer to this yesterday. It's a $5 fix! Check your brake lights. If any of them are out, it will make the cruise control not function. Turns out all 4 of the 3rd set of brake lights were out. We replaced the 4 of them and the cruise control immediately became functional again. I got this tip from a gentleman in the service department at a local Chevy dealer.

There are several items to check. The first is at your brake pedal. You have a small switch on the brake pedal that will cut the power to the cruise control when you step on the brake.

SOURCE: cruise doesn't work on 1999 Chevy Suburban 6.5 Diesel 4x4
sounds like speed sensor that where it picks up the pulse for cruise
SOURCE: MY cruise control on my 03 trailblazer ls works intermittingly
short , loose connection or relay --most likely ---those little green light flicker or come on when generally there is an intermittent short, loose connection or a relay or fuse going to fail soon
and nothing works without a good ground ---one could check if the correct voltage is reaching the cruise contol system and go from there
Just my 2 cents --wiggle the connections --gently ---the cruise control is a complicated sysytem somewhat --you may need another symptom to appear to narrow this down more
but then again --I hate Tow trucks it's a GM --SELL IT Buy a foreign car don't go to ford either
a friend of mine once told me --a 30+yrGM master mechanic that thanks to GM's faulty wiring harnesses and stuff HE will NOT ever want for work and Ford isn't any better --
Get the Toyota if you can that is --unless you are a GM Fan
then sorry my bad no insult intended --

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

how many switches on teh brake pedal ,bet their is more than one
?€¢
The brake pedal position (BPP) sensor
?€¢
The body control module (BCM)
?€¢
The cruise on/off switch
?€¢
The + RES switch (equivalent to resume/accel switch)
?€¢
The - SET switch (equivalent to set/coast switch)
?€¢
The engine control module (ECM)
?€¢
The clutch pedal position (CPP) sensor, if equipped with a manual transmission
?€¢
The throttle actuator control (TAC) motor
?€¢
The vehicle speed sensor
The body control module (BCM) monitors the signal circuit of the cruise control switches, which are located on the steering wheel. The BCM relays the cruise control switch status to the engine control module (ECM) via the GMLAN serial data circuit. The ECM uses the status of the cruise control switch to determine when to capture and maintain the vehicle speed. The ECM monitors the vehicle speed signal circuit in order to determine the desired vehicle speed. The ECM uses the TAC motor in order to maintain the vehicle speed. For further information on the TAC system, refer to Throttle Actuator Control (TAC) System Description for the 2.2L engine or to Throttle Actuator Control (TAC) System Description for the 2.4L engine.
Ignition voltage is supplied to the cruise control switch from the 2-ampere EPS fuse located in the integrated BCM fuse block. The cruise control function switches are arranged in a resistive ladder design, with each cruise control function switch having a different resistance value. The BCM detects a specific voltage value that is associated with the cruise control function switch being activated. When the normally open cruise control on/off switch is turned ON, the switch closes and the BCM sends a GMLAN serial data message to the ECM indicating that the on/off switch is active. Similarly, when the normally open + RES switch or the normally open - SET switch are pressed, the switch closes and the BCM detects the predetermined voltage signal on the cruise control switch signal circuit. The BCM sends a GMLAN serial data message to the ECM indicating that the + RES switch or the - SET switch is active. The + RES switch or the - SET switch will remain inactive when the BCM has not received the predetermined voltage signal from the on/off switch.
Unless the air bag light is lit too , your best bet would be to take your vehicle to a qualified repair shop.
