    Headlight Dimmer Switch Issues

    Sooo..It's fixed! It turns out the tan/white wire and the brown wire were switched. So the illumination was receiving constant 12v. Apparently with this configuration everything still turns on , the illumination just won't turn off. :rotflmao I vaguely remembered having a wiring issue with the...

    Headlight Dimmer Switch Issues

    Unfortunately I tossed the old switch. However, I honestly don't know if the illumination has ever worked in this truck since I've owned it. It's been out for awhile and I don't remember it actually going out so it may have been that way since I bought it. It was a small issue that didn't...

    Headlight Dimmer Switch Issues

    The only wires that make any difference with the illumination is the Tan/White wire ( Pin R ) and the Blue/Red ( Pin I ) . Removing the others wires made no difference. I was trying to see if anything was cross feeding power to those pins somehow.

    Headlight Dimmer Switch Issues

    Is this the correct wiring diagram? My plug is wired differently but it says it's for a '94 which should be the same. I will have to double check but I'm pretty sure my tan/white wire goes to pin R which runs straight to the rheostat.:dunno

    Headlight Dimmer Switch Issues

    I pulled the radio fuse just to make sure because I am running out of ideas. It didn't change anything of course. I inspected each wire at the plug and they all look great. I pulled each wire from the plug , one at a time , to see if I could isolate the issue. No changes. I have no clue what it...

    Headlight Dimmer Switch Issues

    I meant with the switch removed from the dash. Not with the stalk pulled out. Or am I missing something? It's been hard to take everything in with my toddler ... doing toddler things LOL

    Headlight Dimmer Switch Issues

    I've been trouble shooting it with the switch out so I'm sure nothing external is touching it.

    Headlight Dimmer Switch Issues

    Ok , gotcha. For some reason I thought you guys were saying the cluster illumination would still have power with it pushed all the way in. So I was trying to figure out how the rheostat portion was supposed to turn it off. So the cluster illumination should only turn on with the switch pulled...

    Headlight Dimmer Switch Issues

    With the switch unplugged the lights turn off. And with the fuse pulled the lights turn off. I've inspected the wires and they all look good. I guess where I am confused is what actually turns the power off to the illumination. If there is constant power to the dimmer , and the only thing...

    Headlight Dimmer Switch Issues

    So when the dimmer is rotated it should dim down then turn off? It will dim down but it stays slightly illuminated.

    Headlight Dimmer Switch Issues

    So if it isn't key on , and is actually constant , what actually turns the cluster illumination off? I did pull the cluster fuse so the batteries don't drain while I figure it out. I was thinking it may be the ignition switch . But if it isn't key on powered , I'm not sure what it could be at...

    Headlight Dimmer Switch Issues

    This is a 92 , different setup. The headlight dimmer isn't on the floor. However , I am talking about the cluster illumination dimmer , which is part of the headlight switch. I have tried several switches , even different brands , and they all get hot and the illumination stays on.

    Headlight Dimmer Switch Issues

    My cluster illumination was not working but everything else controlled by the switch worked fine. I finally got around to replacing the switch today. The cluster illumination will not turn off now. Ignition off , key out , cluster stays illuminated , and the dimmer portion of the switch gets...

    I'm back in the IDI game!

    Little update on the truck.. She's been running great! There is practically zero smoke at wot / hard pulls. The max I can get the egt to is 600*. There is definitely room for more fuel. But @typ4 's turbo is working a little too good so I'll wait to add more fuel until I do head gaskets / studs...

    Headlight / dimmer switch keeps popping fuse..

    I couldn't figure out how to de-pin that connector lol . It wasn't as easy as the headlight switch side. I hate cutting in to a main harness but the wire was accessible and it was easy to repair it so I went that route. I found the short. It was right under the battery tray. I repaired it , I...

    Headlight / dimmer switch keeps popping fuse..

    So the weirdest thing happened. I cut the brown wire from the main firewall connector , on the engine bay side. I did that to eliminate everything that the brown wire runs to , and to see if maybe it was grounding out inside the connector. To my surprise it didn't pop the fuse and the running...

    Headlight / dimmer switch keeps popping fuse..

    The brown wire is grounded. When you pull the switch out one click for running lights , pin b2 which is constant 12v , transfers power to the brown wire. It immediately blows the fuse. It's possible that I am not understanding the function of the switch correctly. But I'm pretty sure that's what...

    Headlight / dimmer switch keeps popping fuse..

    Ya it seems extremely unlikely that it's shorted on both sides.. but it sure seems like it. :dunno

    Headlight / dimmer switch keeps popping fuse..

    With the main plug on the firewall unplugged the headlight switch doesn't get power. But If I jumped power to it I am 100% sure it would pop the fuse because that brown wire ( that runs to all exterior lights ) is grounded. On the engine side main plug the brown wire pin reads 78omh and is...

    Headlight / dimmer switch keeps popping fuse..

    It looks fine. I pulled each pin out and looked for any signs but it looks perfect.

    Headlight / dimmer switch keeps popping fuse..

    Thank you!! That helps a lot! I have been trying to understand the wiring diagrams but I'm not very good at electrical stuff lol. The headlight switch pin B2 is constant 12v and when the switch is pulled out one click for running lights it transfers power to the pin R which is brown and runs...

    It doesn't but it has a a visor with lights. I disconnected it and it still popped the fuse.

    Headlight / dimmer switch keeps popping fuse..

    I've been trying to figure out this issue off and on and have made very little progress. I've gone through about 40 fuses LOL. I pulled all of the bulbs , inspected every socket , verified the headlight switch is good , disconnected the running board and visor lights,checked and unplugged the...
