checked connections. No power at 3rd brake light.works occasionally when I slam on brakes a couple times. Usually 3 times. thinking about changing rcdl relay under hood on drivers fender

You are wrong if you meant RCDLR relay. It might be the CHMSL RELAY, depending on the date of mfg.

The CHMSL is on a different circuit from the regular stop lights. It is a lot more coplicated than you might suspect.

Yes that's the one. I was reading about it somewhere on here. It's on the inside driver fender. I was gonna replace the relay. It's like 10 bucks. Worth a shot.

A relay would not care how hard you hit the pedal.

Again, sounds like a poor connection.

I know it's not really how hard I press it, more so as the amount of times. Usually takes 3 times. Works fine some times. Connection at the bulbs is ok, changed the pedal sensor, I'll check that connection as well. I figured swap the relay for a new one, didn't know if it was a bad relay or connection there, not sure

You said you had no power at the brake light. Now you say connection at the bulbs is ok. Can you clarify?

jjoverit

No power but connection appears to look ok. No corrosion. Had vehicle running with brakes applied
