So my son's Malibu brake and blinkers are not working? Now the odd part the trunk center brake light works and the front blinkers work. I am at a loss as to what it might be I have look at diagrams and just can't seem to figure it out...

I would check to see if voltage is getting to the plugs themselves. ..then trace back further if necessary. ....the blinkers and brake lights...have seperate bulbs if I remember correctly . So it makes me doubt a socket problem.

Thanks and yes both separate bulbs.

If your taillights have bulb sockets mounted to a PC board, that alone could be the issue. If they're the usual socket with a pigtail, then check the bulbs when you're back there checking for power.

In my 2011, the CHMSL is powered with a separate fuse and relay from the other 2 brake lights.

Check your fuses and look for any relay that might suggest it's for the lower brake lights.

If someone at one time added a trailer hook-up, it could be part or all of the issue.
