2002 tacoma when I signal my hazard lights turn on

Hey guys. When I signal either way all 4 corners light up, I bought a new flasher relay but it seems to just be dead when that one is plugged in and I get nothing. So I put the original one back in checked all the fuses and still having the same issue. I click 4 ways that works. I signal either direction all 4 lights turn on anyone have any insight on this?

 

IIRC the common point is actually your hazard button because if you take it out your blinkers won't work. Stands to reason it could break/short and all would turn on when either turns on, as you describe

 

Does your truck have the Evil Converter box for the 4Pin trailer plug?? They can cause interesting problems with lights.

Any Alarm or parts of one??

A failed Turn Signal switch could cause that problem energizing both right and left turn signals at once.

Physical damage to the wire harness allowing the right and left turn signal to short to each other but not to ground.

You bought a new flasher that did not work at all??

Time to break out the meter check what is going on

Good luck!

 

Maybe I’ll order a new hazard button see if that works, the new flasher did not have any power going through it.

no alarm and no parts for one but I do have a trail 4 pin. Just wrapped around under the bed. Never even looked at it yet. It’s from the previous owner.
