Dash won't light up at night.

I have a 02 Tacoma with the day time running light system. At night my dash and tail lights wont light up. My headlights still work and they are always on because of the DTR light system. I just need a wiring diagram so I can start diagnosing and singling things out. The one weird thing that I noticed is my number 4 and 5 10a headlight fuses only have about 2 volts going through them, maybe could have something to do with the problem? Thanks!

 

Have you checked the 10A Tail fuse?
It powers some of the dash lights too.


Check you messages. I sent some info that might help.

 

Tail fuse is good. I think I’m just gonna start going though the circuit and isolating things. Any other troubleshooting tips?

 

Are you getting power to the Tail fuse?

 

Yes.

 

Have you checked the dash light dimmer rheostat yet?

 

That should not cause the tail lights not to work. I’ll have to look at the diagrams again. But the tail fuse powers both the dash and tail lights.

 

Doh, I read it wrong the first time. I was thinking that the tail lights did work.

 

Hey guys! Finally had the time to do some digging. I’ve been looking at the diagram and seeing what other symptoms I’ve had. I saw things like A/C controller, glove box light, ext. And noticed those are also not working. I checked the tail fuse and tail relay so those are good. I think maybe it could be one of the two I circled in the picture. Either the light control switch and what I think appears to be a junction. Does anyone have a diagram for the light control switch?(the switch that come out on the left of the steering wheel) I want to make sure there’s nothing wrong with that so I can move on. Thanks!

 

Another question. What is the integration relay? Is that in the interior fuse box?

 

Do the license plate lights work?

Also, check your messages

 

No they do not. And I did thank you for the diagrams

 

I tested the light control switch and didn't get any change/signal out of the black and white wire. Lucky it was cheap, and its all working now. Thank you for the help.
