Turn Signal Issues.

Here's my issue:

A few weeks ago when I was driving my '94 Ranger 4x4, the turn signals stopped working. I checked them out when I returned home and here is what's going on:

When headlights are off:

-Turning on left turn signal, All signals flash, including license plate lamps and dash lights. Left signal indicator on dash works as if they're on correctly
-Turning on right turn signal, functions just fine.
-Turning on Hazards, all four flash, including dash and license plate lamps.


When headlights are on:

-Turning on left turn signal, No flash from any of them, drivers front gets a little brighter, as well. Left indicator on dash stay solid.
-Turning on right turn signal, works correctly.
-Turning on Hazards, no flash from any of them, but fronts gets brighter. Indicators bulbs on the dash stay solid.

There were aftermarket LED taillights installed when I purchased it, and Halo Projector Headlights. I removed LED tails and used a normal bulb, and no changes in the above. I switched bulbs out of all four turn signals and nothing changed, as well. The projectors are not hooked in, nor are any other accessories.
It does have a towing package, and all wires there are properly connected. I also checked all fuses and none are blown. When I replaced a signal fuse with a higher amperage one, they functioned fine for a little bit, but now they are back to the above.
I also replaced one the flashers and that didn't resolve it.
Tried new Multifunction Switch and Headlight Switch and nothing.

The only thing that resolves the issue, is when I pull the green/orange wire from the plug going into the MFS, which leads to left rear turn signal, that stops all the problems, but obviously then I don't have that signal.

Any answers? This became urgent because my car just decided to start acting up and I need my truck fixed ASAP so I can drive that.

Thanks in advance,

Zack
 
I had a similiar problem when I bought my truck,used.It took me awhile,but I had to trace all my wires(signals,and tail lamps)and found a hot that had the insulator cut and was grounding.I also found others that were the same way contacting each other.Wiring problems can be a real headache,just follow all your signal wires etc. from end to end,and be sure to look for signs of where the previous owner might have tapped into a wire that he might shouldnt have.Good luck,hope you fix it
 
Also check your grounds to make sure they arent loose or not making a good contact at the frame or engine
