99 S-10 Blazer Brake Light?

[wrightway]

Not sure what to look for next need help

 

Rear left side brake light not working

 

Works when the right side turn signal is on but if the turn signal is turned off I lose the left brake light

 

Left turn also works fine

 

I have checked all the bulbs and wiring in the rear looks good

 

I have also removed all trailer wiring did not help

 

thanks

Sounds like the turn signal switch.
