Hey guys electrical problem here.

Whenever I hit my right turn signal, my hazard lights blink instead and have a hyper flash going on. Also, all the interior lights blink with it. Not the dome lights, but the lights on my 4x4 shifter, my radio lights, heat/ac lights, and all dash back lights blink with the hazard lights in sync. Also, with my key forward to the on position, with the truck off, if I hit my right blinker i get the blinking hazards and the "key in ignition" warning buzzer sound beeps with the blinking. This started a couple weeks ago. Before it started, I noticed that when my lights were on, one of my blinker indicator lights on the dash would flicker a little bit, but this would not engage the blinker. One more thing, I have a hyperflash going with the left blinker as well. When my lights are on, my right parking light does not turn on, but when I turn on the blinker, it does come on and flash.

Not sure where to look right now. I do have some cheapo led parking lights and the updated led flasher relay installed. I am replacing the parking lights next week. Its driving me crazy, and causing some problems with other drivers not knowing what the hell I'm doing. :fca5278d:

I did install the LMC heavy-duty headlight wiring harness a year ago, and I have double checked my grounds for that harness a couple times. I believe I have good grounding points for all ground wires.

Any help is much appreciated! Thanks!

Mine did the same thing. Was the multi function switch (blinker/windshield washer/high beam/cruise control assembly)
Beware aftermarket brands with these switches. I have used a couple different ones and none had the functionality of the original oem unit.
