Hey I just replaced my switch on the steering column. I thought it would fix my problem. What is happening is my high beams don't work. No blue indicator light and no brighter lights. But when I pull back on the column switch the blue light does come on and the lights work. So I have to drive with my hand on the switch to have high beams. And also that same switch has the turn signals when you push it up and down. Well that doesn't do anything when I push it up/down. No indicator lights and no turn signals. But also my hazard switch works fine when I push it all turn signals at 4 corners work fine. So what am I looking at here for a fix?

 

Ya I dunno what it could be. It's not the switch on the steering wheel. It's not the fuses under the hood. I'm pretty sure all my fuses are okay inside as well. There must be a hidden relay somewhere. Or a ground. I'm looking for anyone who might know a relationship between the high beams and signals not working.

 

Okay where is the turn signal ground? Anyone?

 

AAAAhhh I am so confused about this. What is the correct question to ask and get a response? I'm trying to make it easy...

 

Sounds like a short to me. I would check to make sure all wires are hooked up snuggly.

 

how do you know its not the selector switch in the steering column?

 

I know it's not the selector switch because I changed that out and put in my parts truck selector switch and it still didn't work.

Hmmm a short. Yea I guess I need to keep hunting for it. Hand signals for the time being... LOL

 

for the highbeams, did you try pushing the stalk forward? toyotas pull back for "flash to pass" and push forward to stay on. Don't worry, the manager of a shop I used to work at found out about that while I was there...after 35+ years working on cars.

For the flashers: the common points are power, switch, and wiring up to the flasher module (little thing that looks like a relay that goes "click click" and makes them flash. those parts are also separate from the hazard circuit.

 

Yea I tried pushing it forward and it does not do anything. The flash to pass pull back works though.

 

Ground

Check that flasher relay. But I think i remember when my relay went out the turn arrow light stayed on constant so makes me think there is a ground somewhere. Were you experiencing these same problems before you changed out the switch?

 

then you probably have two bad multi-function switches. the only difference between flash-to-pass and high-beams is an electrical contact that provides ground in the MFC.

 

Hmmm I kinda find it hard to believe that both of my switches in 2 different trucks are bad.

I just changed my flasher relay under the steering column today. And everything is still the same. So I have to assume it is a ground or power wire. Or a short along one of the wires. I am getting close now! lol
Right now I think it is a wire near the interior fuse box which is not hooked up. I am going to be checking that next.
I followed the wires. It looks like it goes from the switch on the steering wheel and then into the main harness that runs along under the dashboard. And then I think it goes to the fuse in the kick panel. And from there I don't know exactly but it shouldn't really matter in my case since all my flashers work with the hazard button.

Yea so I will check under the kick panel area for loose wires. I might have messed something up under there. Because when I was taking my truck apart I took all those wires out. It was a good idea because I had to weld in that area to make firewall tubs.

Thanks hopefully I won't have to come back here for more guidance

 

I Should have clarified: the high beam issue is most likely a bad MFC.

 

I don't know what is an MFC?
