Anyone can give me tips at what to look... turn signal and brake light stopped working at the same time. Fuse are good and day light is working (front and back). first thought is the relay. But why would brake light be affected? could a burnt bulb cause this kind of issue (no more turn or brake light front and back)?

thanks everyone

How did you check the fuses? A visual check is not good enough. A fuse can control more than 1 thing and may not be marked as you think it should be.

 

a burnt bulb usually only affects on corner of the vech......like left front or left rear.....but not all the way around....i would look for a bad ground wire or broken wire....you could also have multiple issues at the same time.....bad ground...bad brake switch.........good luck

 

I believe all of them go trough the turn blinker switch too. Make you have the right DC coming out of it.
