My left turn signal flickers as if a bulb is out. I checked the bulbs and none are out. And I looked for the fuses but I can't find the fuses for the turn signal I need a little help finding out what's going on. Thanks

If you mean it just turns off and on intermittently without the turn signal being activated by the turn signal lever. That sounds like the bulb is losing connection to the socket (while bouncing around) or maybe a wire is shorting out (plastic wire jacket worn through). Make sure the bulb is plugged in securely and the contacts on the bulb and socket are clean and making contact. Check wires leading to the bulb for worn spots where the metal wire can short out on the truck's metal somewhere.

If the bulb is snug and no apparent short, check the flasher.

Just like in a thorough Pre Trip: Make sure it is all SECURELY MOUNTED.

Well, you can't 'check' the flasher. Replace the flasher :)

Something like this happened to me this morning. My left turn signal wouldn't flash, and the 4 way flashers wouldn't either. It was 4 am so i just decided to drive and deal with it later (I could fake a flashing left turn signal by turning it off and on), but after a little driving it started to flicker, then later it worked ok. It rained really hard over the weekend when I was parked for a reset so I suspect it might be related. Maybe something dried out once I started moving.

When use my turn signal it flashes rapidly as if a bulb is out . My 4 ways working normally. I put a new bulb in but it's still not working probably. I looked behind the glove box to see if a fuse maybe bad but I can't find the fuse for the turn signal. Are the fuses for the signal located else where ?

If a fuse was out you would have no power to the turn signal, which means no turn signal at all. Is it possible a heavy duty bulb was put in instead a normal bulb? I have seen that cause irregularities in automobile turn signals and boat trailers.

Plug and unplug the conection to the trailer several times and see if that doesn't fix it. Then try and move it around while plugged in and see if it doesn't start working. If it does, some times you can wedge a pic of paper or even a tooth pick beside the connector and it will get you moving and you can report it when you drop the trailer off or you get to a terminal. Most of the time just unplugging and plugging it back in will actually fix almost all of your problems. LOL!

Terminal:

A facility where trucking companies operate out of, or their "home base" if you will. A lot of major companies have multiple terminals around the country which usually consist of the main office building, a drop lot for trailers, and sometimes a repair shop and wash facilities.
