Replaced turn switch with OER. Jumped fuse and both flasher relays. When left turn or hazard engaged, switch overheats/ sparks/ smokes. Switched out to original OEM switch and exactly same immediate overheat. Any ideas, guys? Dig further into steer column? Ignition switch? Hoping to get this resolved. Thanks in advance for your advice!

Fuse should be blowing? Pull all bulbs and see. Some of these bulb sockets have springs under the contacts that could short to ground. Visual inspection of the sockets is a next step.
Unplug the wires to the rear at the left front kick panel and see what it does. If ok the short is from there to the rear lights. If not ok unplug at the bulkhead under the hood the front lighting harness. If ok the short is in the front from the bulkhead to the bulbs. If not ok the problem is in the dash area and could be at the cluster. Unplug that and see what happens. If ok the short is in the cluster. If not ok there is a wire from the column into the main harness shorted.

@pnora nailed it. Process of elimination & having a handful of AGC 20A fuses help. Allow the fuses to save your wiring as you test
Hey thanks very much for the detailed diagnosis flow!
