On most of the trucks the hazard flasher is not mounted on the convience center where the turn flasher is located. Look to the rear from the convience center location above your shins near the obd socket on the panel backside should be a small round flasher with two wires. I'm not sure when the year or location may have changed. But it will be in that area. A flasher is just that, it note a relay as a remotly activated switch. A relay is a relay switched on or off. A flasher activated is self controlled. Apples and oranges. Your 93 has separate flasher reach under dash next to obd socket in a u clip.Remember LED s are electronic. Grab that sixty watt lightbulb feel that? Hot huh? The resistance of tungsten filament creates heat, the current flows through the flasher as the bimetal contact heats and expands and contracts it makes contact, flash then cools flash off. LED's don't have as much resitance therefore the flasher see's full current immediately no momentary buildup. Fast flashing. Same as if your tail light turn signal bulb burnt out. LED's have wide voltage operating range. My maglite leds bulbs 2 D cell to 6 D cell. Same bulb. Ever tryed that with regular incandescent? So your turn signal flasher is probly not your problem. Wiring or need a electronic hazard flasher. Class over.
