2004 Chevrolet Trailblazer Q&A
2004 Chevrolet Trailblazer Question: cruise control
Cruise control failure could be a failure electrically or mechanical. Have you a Service Engine Soon/Check Engine Light on. If so a scan tool is required to retrieve the trouble codes from the on board computer in your car. Look on Autozone's website once you register they have a lot of workshop manuals for popular cars on line for free. - patrick mannion
Hello ,, the cruise control will not turn on the check engine ligt, because it is not an emmission related fault, however there might be a code stored in the body control module that might help in the diagnosis.. the most simpliest problem to check for , is make sure all of your brake lights work, a burned out bulb will cause cruise not to work - mastertech154
my truck will not go into cruise or downshift by it self when i floor it. i need to manually downshift it. it is showing a p0107 code.
the indicator light does not come on when I turn on the cruise control switch. I am not sure but this failed around the same time I replaced the turn signal flasher...
Some told me about thermostat but gauge shows normal
it worked fine untill i went to the beach
...eedometer works fine for a while and then it slowly goes down to zero. What is strange is the cruise control works fine all the time. When I'm stopped at a stop sign, I hear a clicking.
