Hi everyone,

I've scoured the forums but I'm stuck chasing a ghost and hope you can help. 96 XLT keeps blowing fuses when I turn on the left turn signal or the flashers. Blowing both the #7 & #13 fuses. So far I've done all of the following and still can't seem to find the problem.

Replaced the turn signal switch
Checked connections at all the bulbs
Traced wires from back to front and can't find any bare/crimped wires
Checked connections at all 3 brake lights, disconnected 3rd brake light for testing- still tripping fuse
Swapped flashers in the fuse panel with known working units
Trailer 7pin connection was damaged in a rock crawling incident, I pull it all apart, fixed and rewired everything to make sure it's not grounding out

The problem seems to have started after I replaced the tail light lenses with new ones, but I can't find any evidence of what changed.

If it's a bad ground, can someone tell me where all the ground locations are so I can check? I have a multimeter, what can I test?

TIA

Thanks Miesk, I'll run through all those points again (I found the crimped wire post on another thread but without the diagram) but I have not tested the rear window connection yet. I did unplug it where the top meets the bedside to try and rule out issues with the third brake light. I'll test and report back asap.
