Are there any updates for the question on no brake lights, but the third light works.

Mr. Obvious, Here. I Don’t Know What Updates You Refer To, But Have You Checked Fuses And Bulbs ?

It is possible for two bulbs to go out and they don’t necessarily go out at the same time. One could burn out and unless you check frequently you may not notice until the second one burns out.

Also, some of these vehicles have moisture problems in light assemblies. While checking bulbs, one should check for moisture and corrosion in the bulb sockets.

Please tell what you’ve already checked.
