well if you read my previous post abt my 750$ s14, im getting into the repairs finally. well i left work @ night and i had no dash lights and i had no tail lights. the previous owner, which isnt all there, said there was a fuse behind the dash that controled this (or was told). i have checked all fuses @ the kick panel, and under the hood and they are all working. is he correct, and could any of you lend a helping pic/diagram where this answer lies ? i read somewhere about a tcu, or possibly the headlight switch itself...i have searched, thats why my thread count is as low as it is for being a member for this long :P. thanks.

My s13 did the same thing, I checked all fuses I didnt find anything. Then I found my license plate lights all chewed up ( damn rats ) Well after fixing that the Tail light fuse blew. Replaced that and now both the sped and tails work.

tach doesnt work either. this had some aftermarket cruise unit and looks like some kind of alarm system as well. wires ****ing everywhere ..spliced here spliced there, very very shady work. i spent abt 4 hours tracing back and removing all the ****. runs like it did, but still didnt fix my problem...still no lights and no tach maybe someone has been in this situation can give me a hand? im leaning towards replacing the switch and the tach itself...but both the lights and the tach would be wired into a cruise unit and alarm system...no? *bangs head*...well off to work maybe someone can give me some suggestions. thanks!

Is it a HUD equipped model? I know most HUD with the digital speedo have issues with no dash lights. Its a saudering point on the Digital speedo's chipboard....maybe something similair?

unfortunatly not, if it were so it would be an easier assumption. im pretty much down to stock wiring, i just dont know where to go from here other than replacing switch. *shrugs*

threadjacking ftl.... anyways, i bought a test light today to make sure the fuses work, every fuse works. so this is my theory... in order for this test lamp to work, there has to be a closed curcuit within that path (@ fuse tested). so this would rule out any wiring problem, and i would assume its the switch (headlight, dash, tails, signal, etc)...correct? this is pretty much the only thing stopping me from driving the car atm (night job )

thanks.

maybe...you have same thing happening too? but blowing fuses... hm. blowing fuses is definatly something grounding out, wires touching that shouldnt, etc... could even be switch related as well, maybe something broke inside. but i think you definatly have a wiring issue.

I don't know about S14s, but I had the same problem in my S13. It ended up being caused by the big alternator fuse by the battery being blown. Check yours to see if it might be bad. It's the big gray 75amp one.

this is what i found when i decided to see whats up behind the dash. 2 burn marks, looks almost like solder. when i turn the ignition on (was testing positives), these 2 points get rediculously hot.....from any of your guys experience, you think this may be the problem? no lights and no tach....

man pull your radio and tape up any bare connections and i mean ANY because i had the same thing happening to me after i first got my first 240 and the dumbass was too cheap to buy the right harness adaptor and just cut the plug off and did a halfassed job of hardwiring the cd player. And he had like 5 wires behind the radio sitting there with bare connections. And it turned out the illumination wire was touching metal and everytime i turned on the lights it'd pop.

no bare wires from the stereo harness, or any other section near the dash, under the dash, etc... checked and rechecked. thanks for the reply tho some people are retarded, example is in my driveway.

took radio out so less to deal with. i did however find a blown bulb in the cluster, dunno if that would cause the entire circuit to fail. gonna get a switch and go from there. also read about the dimmer being a part of the problem in this circuit...dunno how to bypass it tho. i have a feeling ill be ripping this entire car apart.

decided to put interior back together and clean out the car after ruling out some wiring areas. interior gets pretty messy when its your work area lol. well i unplugged the harness going into the dim switch, and i tested with my light and its not getting any juice in either pin (3), and i turned the switch as well and tested off/park lights/headlights. related, probably, just thought id post this up.

lolz, haha unfortunately not as many people know about wires as they do rims and tires, i jsut bought a s13 coupe with the hud speedo, and anyways none of the interior dash lights work. so im hoping to keep searching and find a write up.

gl, i had to rewire the positives running the dash and the rear lights, had to find them tho, + changed out the main harness. yea your pretty much on your own for wiring around here, not much in the way of good advice.

You don't have a local auto electric shop around you?

A place did my car for 70-80 bucks, found out my alternator was overcharging, blew the main alt fuse, fried the gauge cluster, and several of those black or white boxes under the dash...
