Check the socket on the third brake light.

I was having an intermittent 'check brake light' warning. Sometimes the brake light worked ... sometimes it didn't.

Turns out the bulb socket was melted and the spring contact on the side of the socket was not always making contact with the bulb.

Additionally, the PO had put a brass base bulb in the socket which I have heard is not recommended.

I replaced my socket yesterday and installed a nickel plated bulb. Problem solved.

Most likely 3rd Brake light ( one in rear window)

The socket is bad and partly melted. I had same issue kept on changing bulbs. $7.00 for new socket all fixed!,

Did you change the center brake light?

That's usually the problem.

Typing /brake light f3 in the bestlinks nets this, among others:
