Diagnosis assist: headlights - Toyota 4Runner Forum

My 2011 just lost both low beams at the same time, and I think the passenger side front marker light. I’m going to dig into it in the morning and figured I’d ask here for where to check for failure points. I’m going straight for the fuses first, then bulbs. My fog lights and high beams switch properly, so that makes me think my control stalk is fine.

At least it won’t be VW electrical gremlins. 😂

You might want to look up the electrical drawings for those circuits. Nashman posted the FSM in the stickies for (I think) the 2010 model year, which should be pretty close. I wouldn't completely rule out the control stalk just yet. I had one go bad on my Nissan. Everything worked but the Hi-beams intermittently. For sure though, fuses in both fuse blocks are the first place I'd check.

Check the relay too.
