Hey guys, I was wondering if anyone could help me with a fog light issue I'm having.
Basically my left turn signal/fog light will only go on certain times. When I have my lights up it turns off, however when I throw my left signal on it blinks as normal.
Anyone else have this issue?
its obviously a wiring problem...

 

Your '88 didn't come with factory fogs, so whoever installed them had to do all the wiring (they're plug-n-play on a S5).
Obviously, they screwed it up but there's no way for us to know how.

What is a "left turn signal/fog light" anyway?
The TS and fogs are usually two discrete systems.

 

yeah sorryy I meant just my turn signal
