Recently I was pulled over because my tail light was out. I found this hard to believe because it was so new. Anyway long story short, my driver side park lights are out. (Front signal; rear tail) Do not come on when my lights are on. Once I throw my left turn signal both lights work, and when I apply my brake the rear works as well. I have troubleshot the exposed wires that I can see and there are no loose wires. I am wondering if anyone has ran into this before or knows what may be the cause,

 

I do recall a thread on this recently but I don't recall the title or the possibility of a solution.

Is the left front side marker light out, too?

Check fuse M17.
It supplies power for the left front park and side marker lights, and the left rear park light.

 

Check I bulbs happens to me some times they go out and my break lights work but then my signals don't work and its the same bulb

 

Thank you will check this morning

 

I probably should have wrote this above but I did change both front and rear bulbs.

 

process of elimination my friend. pull out the front driver bulb and see if the rear works as it should. if not, replace the front bulb and remove the rear and try again. again if not, remove both front and rear and check if your still having the voltage drop out like you mentioned. more than likely you used an incorrect bulb type somewhere. this once happened to me on another vehicle. good luck

 

Thanks to all for the help. I pulled M17 this morning and sure enough it was blown, put a new 15a fuse in and they work!

 

The next thing you should be thinking about is why did the fuse blow.

 

I installed a trailer wiring kit a few months back. I simply took the light out and plugged it in. I did not ground that wiring harness. The ground wire I just left loose. I'm thinking this is it because you install the trailer wiring on the left side.
