I have a 2001 s10 4.3l and my problem is that the left tail lights brake light works but not the daytime runner only on the left side, right side works fine, i replaced the bulb and fuse.. i was wondering if anyone has had this problem and hows a fix

if you think its the socket how do you check to know for sure and if so how to replace

thanks

 

Losing connection in the socket perhaps?
