Make sure it is not your bulbs. You need to check your fuse first. Make sure it is not blown. It could also be your brake switch. This is located above your brake pedal. It is a chrome looking round cylinder. If they all check out, it is a problem with the wiring harness. Thank you for choosing FixYa.

SOURCE: chevy trailblazer - brake lights do not work

try checking the brake light switch attached to the brake pedal,very common problem. has about 5 contacts in it ,they all operate different things. If you have a scan tool with live data readings you can watch them all. also check fuses and bulbs ,but you say the signals work so that seems ok.

SOURCE: my speakers at back does not work on my chevy 2007

First, check that the balance switchon the radio has not been set to front only. If not, then pull the radio out and check the speaker wires at the back of the radio for connectivity, if ok, then do the same for the speakers, remove them and check the wires. Hope that helps

How do you bleed brakes on a 2007 chevy trailblazer?


I haven't heard of them being particularly troublesome brakes so presumably using the traditional method should be satisfactory - using an assistant to pump fresh fluid through each bleeder in turn by pressing the brake pedal. Start at the furthest from the master cylinder and work to the nearest.

If the system is dry it might be necessary to bleed the master cylinder first and then allow the system to fill under gravity for a time before bleeding.

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

My mom has a 2004 chevy trailblazer and her brake lights weren't working she changed the fuse they work now but her directionals aren't working at all now


Did she disconnect the negative terminal from the battery when replacing the fuse? Is it possible she swapped fuses instead of replacing them? One easy thing to try is to disconnect the battery for at least 30 min to allow the PCM (computer) to reset itself.

Dash lights


sounds like a problem in the abs brake system, you will need to take it to a dealer to be diagnosed.. it probably won't cause any driveability issues but is definitely a safety concern..

Brake lights not working on my chevy malibu


Check fuse/relay and then check the brake switch under the dash close to the brake pedal. It tells the brake lights to come on when you apply the brakes.
