Stop Lamps
The body control module (BCM) is responsible for controlling the stop lamps. When the driver presses the brake pedal, the BCM will receive a signal from the brake pedal position sensor. The BCM then supplies battery positive voltage to both left and right stop lamp assemblies and to the center high mounted stop lamp (CHMSL). The stop lamps are grounded at G401 and G403. The CHMSL is grounded at G302.
Did you check the blub , is there power ( B+) at the third light ? Is the ground G302 good ? Do you have a DVOM - digital volt ohm meter , do you know how to use one ? Do you know what voltage drop is ? an know how to test it ? Check the stop lamp relay in the under hood fuse / relay box.

SOURCE: brake light on 2001 chevy blazer LT 2wd

When my blazer did this they had to replace part of the wiring harness in the steering wheel. It took forever for them to get the parts because we live in nowhereville, but once it was in it works again and no problems. I had to take it to the actual chevy dealer because none of the other places had a clue. good luck.

SOURCE: My third brake light dosen't work on my chevy s10 94'

I had a similar problem with my 1994 S-10 LS extended cab. Both tail brake lights worked fine. I removed the 3rd brake light cover and tested for voltage at the steel center of the two rivets and found the positive (driver side) negative (passenger side) were good. I checked the two metal strips that send power to bulbs and found the positive side was open. Seems the flared side of the rivet was not making contact with the metal strip. I bucked the rivet with a punch and hammer and it took care of the problem.

SOURCE: Change headlight on 2008 Chevy Malibu

Hi there,

Well first you can please follow the below steps -
1. Make sure the ignition key is in the off position and the headlight switch is off. Release the hood latch.
2. Open the hood and locate the top of the headlight assembly where you intend to change the headlight. If a plastic shroud is present, locate the center bolt and remove it with a ratchet and a socket. Lift the shroud out of the way to access the headlight assembly retaining brackets. Some later models may feature a snap-release shroud requiring no tools to remove.
3. Locate the brackets on the top rear of each side of the headlight assembly. Lift them all the way up to align the hole on the bottom of each bracket to the retaining tabs on the assembly.
4. Pull the assembly forward away from the Malibu, but be careful not to scratch the bumper. There are three guide pins that require unseating. The guide pins are what aim the headlights and it may take some wiggling to get the pins from their seats.
5. Support the assembly with one hand and then reach behind the unit with the other. The low beam bulb is on the outside, the high beam bulb is on the inside. You can also replace the parking light if desired. Locate the wire harness connection. Un-clip the wire harness from the back of the bulb socket. Remove the bulb by turning it counterclockwise 1/3 of a turn to align the release tabs of the ring and the assembly. Wiggle the bulb out of the assembly.
6. Place the latex gloves on your hands before opening the package of the replacement bulb. Oil in our skin can damage the glass bulbs of halogen headlights.
7. Carefully insert the new bulb into the ring and then align the tabs of the ring to the tabs of the headlight assembly. Push inward and then twist clockwise 1/3 of a turn to lock the bulb in place. Reattach the wire harness. Rest the headlight assembly inside its cavity and test the operation of the headlight before securing the headlight assembly in place. Be sure to turn the lights and ignition back off.
8. Align the three guide pins to their seats and push the assembly back into them gently until they snap into place. Replace the retaining brackets by pushing them downward to lock into place. Replace shroud, if applicable. Remove the tools and old bulb and close the hood. Post comments for further help or information......

Good Luck!!

2008 Chevy Malibu check engine light and traction control light is on but im not losing power. also third brake light is out was working fine earlier.


Check engine light on ? Have it checked for DTC'S - diagnostic trouble codes . All problems maybe linked together . If you don't want to take to a qualified repair shop , auto part stores will check codes for free ,most will ! i hear advance charges $20 now. Third brake light may just be a bulb or the Stop lamp relay in the under hood fuse box.

How do I replace the high mount brake light on my 2011 Chevy Malibu?


You need to take the back seat out. Remove the C-Pillar trim panels. Lift up on the package shelf. Unplug the wiring connector. I've had mine out when I changed the speakers.

BTW, Its Not a Bulb. Its a LED Assembly. Replaced as a whole unit. Unless your good with electronics and soldering.

How do you replace the third brake light bulb?


If you do not know what you are doing you should go to a mechanic. A simple slip with a screw driver can cost a lot of money.
