Turn signal issues

[fuddmuffin]

Hello,

I just got myself a 1990 bronco 2 and it is having some turn signal issues. Whenever I turn the left signal on my rear hazards come on but not my front, and when I put my right signal on nothing happens in the rear. I just changed out the relay and that didn't work. Has anybody had this happen to them before?
P.S. this bronco was modified by a previous owner

Hey @fudmuffin, welcome to the forum!

Hate to confess this, but if I don't spot obvious electrical fuckery here, I'm going to risk shotgunning the Multi-Function Switch (turn, hazard, wiper, etc). Pretty easy job, just un.s.c.r.e.w tilt lever if present, remove steering column shroud, then two torx fasteners and electrical connector, bada-bing.

Standard brand DS-970

It probably is the multi function switch.

What happens with the marker lights are one and you put the turn signal on?

You said modified by previous owner, does it have trailer wiring? If so you might want to disconnect that, cut it out. That could affect the turn signals if he didn't know what he was doing.
