drewet88 Posted May 28, 2008 Share Posted May 28, 2008 I have a 93 ES250. Whenever I turn on my headlights my rear lights do not come on. They work fine when I step on the break pedal, O and I also have that annoying light on my dash saying one of my lights are out. They use to work but all of sudden they stopped. I changed all of my lights bulbs with 1157LL thats what the book at autozone said to grab. Any suggestions? EDIT its at 1990 Quote Link to comment Share on other sites More sharing options...

kashi125 Posted May 28, 2008 Share Posted May 28, 2008 Have you checked the fuses for them? Quote Link to comment Share on other sites More sharing options...
drewet88 Posted May 29, 2008 Author Share Posted May 29, 2008 Have you checked the fuses for them? Well if you mean the fuses under the dash then yes I checked everyone that I saw but I dont have the panel or a book so I dont know which ones to check exactly so I checked them all. EDIT: I also followed the wires back as far as I could and found no breaks in the wires, I did however find something called a light failure its big and orange and all the wires seem to plug into it. When I unhook it I lose all tail lights. Quote Link to comment Share on other sites More sharing options...
kashi125 Posted May 29, 2008 Share Posted May 29, 2008 I am not really sure about this model, but check to see if there is another fuse panel under the hood. If you have a multimeter available, check the contacts in the bulb socket to make sure you are getting 12V there. Quote Link to comment Share on other sites More sharing options...

I checked fuses under the hood and there isn't one for the tail lights. I'm thinking it may be the lamp failure switch, I read some posts about that causing this problem and when I took it off I could hear something loose inside of it.

I checked the connections with the multimeter, couldn't really sleep so I just went outside with a flashlight and did it. While pressing the break pedal everything gets 12v. With the headlights on not pressing the pedals everything got 1v. I read somewhere that I should pop open the yellow box I talked about earlier because there can be a small short causing this problem. Anything else I should look at will I'm taking stuff apart?

"While pressing the break pedal everything gets 12v" ---This makes me think it is that yellow box / lamp failure switch. Your troubleshooting so far has revealed that it is not a wiring or fuse problem. I have not run into this problem before, so hopefully someone who has had experience with this will chime in. Do post your results once you are successful. Good luck! Quote Link to comment Share on other sites More sharing options...
drewet88 Posted May 30, 2008 Author Share Posted May 30, 2008 Well I googled info on the little box and a lot of people have had it die on them and have had the same problems as me. They opened it up and resoldered, since I have no experience in soldering and a new box costs about $250, dealer only. I went to 2 junk yards but all of the little yellow boxes were gone are messed up like mine. I started checking wires again and saw that the license plate lights still cut on so I just spliced those into the green wire that controled the running lights. I used an inline fuse 20amp and some make some nice strong connections and then protected everything with electrical tape just in case, fixed everything. Now when I turn on the headlights the running lights come on but this is just a temporary fix because bypassing the little box means the dash will not tell me if a tail light is out. I fused it just in case I'd rather be safe than sorry and have an even bigger problem to fix. Thanks for all your help everyone let me know any thoughts/comments you have.

kashi125 Posted May 30, 2008 Share Posted May 30, 2008 wow nice workaround there! BTW if you were able to do all that, I think you would have no problem soldering. It's pretty easy--just read up some info online. Quote Link to comment Share on other sites More sharing options...

Lol thank you looking at it it did seem pretty easy, maybe I'll go to walmart and get one and see what I can do on some other things before I try soldering that little box, who knows what else can be messed up if I do it wrong.
