My brake lights work, but tail lights don't. Tail lights blink on when I click to unlock car.

Check the bulbs and the connectors they go in. Check for loose or corroded grounds in trunk.

Bulbs work when I turn on flashers.

Flashers work off the brake lights Park lights are on a separate wire.

It was relay. Thanks for your help.

I have same problem but a 2012 Chevy Malibu LT just the tail lights are not working

On my 2007 Malibu, the rear drivers side tail light worked but the turn signal didn't. I bought a new bulb and installed it but the problem didn't go away. I looked at the old bulb and both filaments were fine. I looked at the contacts and one side was black and corroded. I tried using a needle nose pliers to rough up the contact but at the slightest touch, the contact broke off. There was no way for me to re-install the clip fragment that broke off so I just took a small piece of aluminum foil, folded it into a small enough piece to fit where the clip had been and ........it worked!!

My break light don't come on when i hit the pedal & my tail lights not coming on but my signal working
