New to the forum; first Tacoma. Help please with headlight problem.

I'm having trouble with the headlights on my truck. High beams work, but no indicator light on the dash. No low beams. The problem started after I had the cover off the the steering column for another repair. The low beams flickered on and off and finally quit working. I assumed it was a wiring problem.
I have the switch apart now, and by crossing 2 terminals on the switch, I can turn the low beams on, so I know the bulbs are fine and the wiring works. the swicth looks fine inside, no corrosion or visible damage. Also, the switch is rather complicated, but I cant see any positon that cannest the 2 terminals I crossed to turns the low beams on.
I'm stumped on what to look into next. I don't want to replace the switch untill I am sure that is the problem, but I don't know what else could be making trouble.
Any ideas? Thanks in advance!

 

I'd replace the switch, but that's just me.

 

Maybe I just need to try replacing the switch, but considering that the original switch looks fine and that a new switch is $140, I'm not sure if I want to do a switch now. Maybe I can find one at a junkyard.

 

Welcome to TW!

 

Depending on if you have a US or Canadian spec truck the headlights operate very differently, assuming you have a US spec truck Pin 12 (Red/Yellow) is the low beam wire (If it's Canadian spec Pin 12 will be Violet). Grounding that wire with the headlights on should turn the low beams on.

 

Thanks for that. I was grounding pin 12 (red/yellow) to turn on the low beams. I take it you're implying my switch is bad then?

 

Need to verify the ground is good on Pins 9 & 11 (White/Black) but if that's good yea it would seem your switch is bad.

The high beam indicator I believe is a separate issue likely just a burnt out indicator bulb.
