having problems with rear blinkers and brake lights. first the driver side stopped working now a few months later passenger side stopped. front blinkers still work. wtf is going on

 

probably burnt out bulbs

 

bulbs are both fine. fuses are fine also.

 

check for proper ground at the socket as well as corrosion in there

 

also check to make sure the bulbs havent melted anything in the light fixture. Ive heard of ppl using aftermarket lights and it isnt the right voltage and ends up melting vital parts of the light fixture..just an idea

 

id have to say go with checking the grounds thats always a good spot to start if bulns are good and nothings melted check the ground had a head light in my 89 blazer that was dim and would get bright as the blinker turned on and off riped apart the hole front end but found it right up front where i dint need to pull a part anything
