My headlights just started to go off when I turn them on... I was on my way home tonight and noticed it was pretty dark in front of me, so I checked my headlights by turning them off then back on. When I turned them on, they immediately went out. I restarted the car, tried one headlight at a time, no success... not sure what the problem could be?

Back in November, I had a short in one of them. When I turned them on, they would flash 3 times and go out because the tipm found a problem with them. I repaired that by just rewriring the bad one and it’s been fine ever since. This time they don’t even flash, they just go out. Doesn’t matter if I’m using brights or low beams

Update..

They do try to come on several times when I turn them off then go out for good. I tried as best I could to get a voltage read from them and it’s only coming to about 1.6 volts. I tried what I did last time by only doing one bulb plugged in at a time and it did it with both sides. So it seems as if they’re not getting enough power for some reason.

Time to chase wires/connections and find the short, or corrosion creating the low current.
You can also unplug both lights and just use a test light in the plugs, to see if it will stay lit.

Thanks. Will try tomorrow

Disconnect the Neg(-) battery cable and isolate it. Then disconnect the Pos(+) battery cable from the TIPM.
Then release the TIPM from the brackets and roll it over.
I found a wire under my TIPM that was rubbing a hole on the bracket.
Not saying that is the cause, but worth looking at.
When done install the Pos(+) cable to the TIPM, then, and only then, connect the Neg(-) to the battery. The disconnect/connect sequence is very important!

It’s strange that it’s both lights this time. Last time, if I unplugged the passenger side, the driver side would stay on

What was the solution last time with one light?

 

[appleb11]

Last time, I just rewired the bad light and it’s been working good.

I actually just bought a new multifunction switch. The connectors are showing same volts off or on so thinking it might be that. It’ll at least hopefully fix my turn signal issue where it’ll stay on after turning wheel back straight although that doesn’t bother me as much as my headlights not working.

Any idea of the procedure to change out the multi switch?

when you say rewired the bad light, can you tell us exactly what you did ?.

i can see the problem you are having trying to test the headlight voltage, the lights are switching off straight away so it is not possible to get a voltage reading.

i am looking at the wiring diagram to find some way of testing the headlight circuit, but as there is no voltage, you can only test for a short circuit, and it is not so easy, also still involves lifting the TIPM.

as ScarO says this looks like you could have a short circuit in the wiring, if your multifunction switch is faulty then you should change this first, maybe it will cure the problem, (fingers crossed ),


Changing the multifunction switch:

First disconect the NEGative battery lead ( very important ).
i don't have any instructions but it is fairly easy, remove the cowl from around the steering column ( you can lower the steering wheel to help get to the screws ) you will then see the screws holding the multifunction switch, remove these screws and disconnect the harness connector. i may have missed a couple of things, but as i say it is fairly easy.

Thanks, and I basically just cut the wires near the tipm for the passenger headlight and put new wires in connecting where I cut to the new connector. I don’t get why it’s both of them and everything else works fine. I’m about to just switch the wiring with my fog lights and be done with it haha. Only a few more months till I have this thing paid off

well looking at the wiring diagram the only connection between the 2 headlights circuits is the multifunction switch.

the headlights don't have a direct ground wire, the grounding for the headlight is controlled by the TIPM, the 3 wires for each headlight are: 1 wire low beam +12v , 1 wire high beam +12v, and 1 wire is the return signal - ground, but will only give voltage or a ground when turned on.

 

[appleb11]

Okay, well hopefully the multi switch is my problem. Only thing that really makes sense

 

[Nitrogen]

fingers crossed,

did you try the vehicle computer reset, disconnect the NEGative battery lead for 10 minutes then reconnect, this has solved problem for a few members in the past. it's simple and free .

 

[appleb11]

Yes, I even tried disconnecting both and zip tie them together

This will help with the switch.

Read somewhere that that works for some reason. Or beating on the tipm...

Thanks

 

[Scar0]

Your welcome. Hope that does the trick.
Keep us posted on how it goes.

 

[appleb11]

Will do

Update.. they just started working again. Not sure what the problem was.
