I would suspect a speed sensor.

I have had this same problem on two difference vehicles both of which are suburbans.

The solution is simple.
Remove the engine cover.
Locate a small ground wire that is bolted to the top rear of the engine block on the passenger side.
Remove the bolt, clean surfaces and replace.

This should solve your problem.

I know it seems too easy but it works.

SOURCE: need 02 trailblazer third brake light removal

Open the full hatch.
Pull down the weather strip near the rear dome light.
There should be a wire with a connector in it. Disconnect it
Close the full hatch.

Open just the window hatch. There is 1 screw on either side of the bulb housing.

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

The third brake light is always on and the abs light also frontier 2002


Couple of questions....
when you step on the brakes pedal do the other brake lights work?
does the third brake light go out with the brake switch unplugged?
have you checked for trouble codes in the abs module?

Just had brakes done 2 weeks ago, now my abs/brake lights are on and blower fan will not work?


For the ABS light, bring it back to the place that did the work. May have damaged the sensor or not connected it back up. The blower fan is a seperate issue. If you have manual controls, not auto climate controls, try replacing your blower resistor module. The resistor is a very common thing to go out in TB's and Envoys.

2003 silverado abs/brake light and service 4x4 light comes on heater blower quit working at the same time.


Possible bad ignition switch. Check out video on YouTube called 2003 Trailblazer, no blower, abs and brake lights on. I know it says trailblazer, but it applies to most of gm full size trucks. 2003-2007 including Silverado. Video tells you how to test to see if that is the problem.
