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 --

SOURCE: check engine light on

You cannot reset the check engine light any other way than using a scan tool. Some auto parts stores will scan the vehicle for free then at least you will know the area of the fault.

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

I have a 2007 Chevrolet Trailblazer ls that has a ticking noise when you accelerate but stops when you brake no check engine light is on and vehicle seems to be running normal


Check engine lights do not come on for every possible fault. The noise you hear could be many different things, such as very small exhaust leak, a knock sensor just starting to fail, and others. Best would be if you could hook up a GOOD scan tool that will display real-time data and drive with a knowledgeable helper. Otherwise, you may have to make the dreaded trip to the dealer service dept.

My oil light with a little wrench beside it came on this morning, I have a 2007 chevy trailblazer and I just had a oil change 1 month ago


If the service light is on in your TrailBlazer, open the door, turn the key to ignition position and push the accelerator pedal 5 times, the service light will flash. flash your high beams and you're done.
