Right front turn signal keep blowing the fuse, left front all ran the same way and does not. Changed out turn signal switch due to loose wiring and fixed the issue for a moment, and changed turn signal wiring harness. Changed flasher/turn signal relay prior. Have LED's so went from 10 to 15 amp fuse, again, worked for a moment then cut off. Either looking for a legit wiring diagram to trace ground to fuse box if can’t find any other way to resolve.

Hi,

Take a look through the attached wiring schematic for the exterior lighting system. I broke the pic into three parts to make it readable. I did overlap them so you can follow them.

If you need ground distribution, power distribution, or something different for the entire truck, let me know.

Let me know if this helps.

Suggested Repair

Use the exterior lighting wiring schematic to trace the right front turn signal power and ground circuits back to the fuse box. A fuse that blows again after brief operation indicates a short, so restore the correct fuse rating and do not keep upsizing it. Request ground or power distribution diagrams if the lighting schematic is not enough to isolate the short.

Conversation Summary

The owner of a 2001 Chevrolet Silverado reported that the right front turn signal repeatedly blew the fuse while the left side worked. Replacing the turn signal switch, wiring harness, and flasher relay, and increasing the fuse from 10 to 15 amps for LED bulbs, only worked briefly. The owner requested a wiring diagram to trace the circuit to the fuse box. The expert provided an exterior lighting schematic in three overlapping sections and offered ground or power distribution diagrams if needed.
