Hey guyI wasnt sure in what board to put this in so i choose this one.

This is what happens. When i put the key in the ignition and turn it to acc or on where all the lights in the gauge cluster turn on then i take the key out of the igniton those lights stay on. They never shut of. After a while playing with them thell decide to turn off. and when i say playing with them i mean as key on off on off.

But sometimes thell stay on all the time. I think that the wireharness is not grounded right but were exactly can i look to see if there grounded right or not. On the radio the wire harness was cut and theres its on wireharness by itself its really weird.

But im not sure if thats whats causing the problem.If you guys can help me out by either telling me what you think it is or where you think i can lookin by. I would really appreciate it.ThanksAlex

I have seen this in another post. dont remember if it was in 240 technical or this forum. I dont remember what the final fix was but it was addressed a couple months ago. do a search on dash lights.

Hey NistechI did a sear on dash lights and just dash. but i couldnt find anything. The only thing i found was that dash lights are to bright with the headlights on or some thing.

alright I found the post I was thinking of but it never got resolved. I was helping him and the last post was a question to me that never got answered. I think it was around the time the servers changed over so some of the subscribed posts never showed in my panel. besides his would go out after a short period after turning the key off.

I am thinking you have a short somewhere though. is it only the back light illumination that stays on??

HeyNo what stays on are the oil light the seat belt light the lights on the bottom of the dash. Like when u turn on the switch of the car. u know how some lights turn on and after a couple of seconds they turn off. Well mine dont turn off even when i take the key out. By the way its an 92 s13.

ok your problem is not the same as his is. But I vaguely remember seeing something like that at the shop I work at but it was a couple years ago and I think it was on a Z31 300z. I believe it had something to do with the altenator but not sure. will need to think on this. for now make it so you can disconnect the battery when your done driving so the battery wont go dead and I will check with one of the guys I work with see if they remember the incedent and what we did to fix it. I will get back to you about it probably tuesday night. at this point its the best I can do unless I completely remember the incedent between now and then in which case I will post it .

Hey Nistech thanks a lot. At the moment the car isnt runing yet. i jsut replaced the head on it and i have to do the timing on the cams. So ill try to figure out everything with the wireharness. And ill check the alternator. When the car was running the owner of the car told me that the lights dont shut off. So maybe its since the car hasnt been running there might be something wrong. IT'll be running hopefully if everything goes according to plan on tuesday or wed. and ill post and tell you what happens. But if u still can i would appreciate it to ask your friend.ThanksAlex

ok he remembers it as well but doesnt remember the fix. but in front of me I have the wiring diagram for your dash lights. I will review it and post what might be the problem when I figure it out.

Ok nistech thanks so much. I tried to turn on the car today and we did all the timign and everything but it jsut isnt starting. it cranks but i think that battery is weak for sitting for so long that its not cranking enough. Because at first it started but immediatly shut off. so i pray to god its the battery. Then aafter that i have to figure out the dashboard.if its not to much is there anyway u can send me a copy of the wireing diagram as i am going to have to take the dash out to replace it because mine is cracked in lik 5 places looks bad. ThanksAlex

this diagram is only for the instrument cluster not the entire dash. that would take extensive research to find all those diag. I can however post this diag for you but need to scan it first. give me a bit.

try yankin the bulb check relay. see if they go out or if some go out. if some go out that could be your problem. if nothing happens you will have isolated a large portion of the circuit.

Hey nistechwell i started the car today. and i drove it around for a little bit. And its overheating. i did a system check and i dont have a leak. all the collant starts squirting out threw the overflow hose( i dont have a tank it was removed not by me)unless it jsut donsnt come with one but i believe it does.Any how i think its the thermostate that is stuck. But i am not to sure. Im praying to god its not the head gasket. Because its brand new and i dont feel like taking the head off again. i check the fan clutch and its working fine. Same as the water pump. There is pressure in the radiator and system. So my only things can be either headgasket or thermostat. So right now about the dashlights i am going to put off for a day or two. till i find out the motor is working with no problem. and not overheating or anything.So ill let you know whats going on tom.BYe

you need to get the coolant over flow bottle in there. coolant is suppose to go into the bottle when it warms up and draw back as it cools down. keep me up on whats going on.

ok. i guess i have to go to a junkyad and find the bottle. Dats going ot be hard as i barely got to find the cam shafts.And i trully believe its the thermostat. i bought a new one today im goign to install it tom. and ill update you with what happens.How important is that overflow bottle. BEcause i have the bottle in my supra. and the bottle is just an emrgency coolant if it needs it.

it is important since the system will push coolant into it when the car is fully warmed up that is coolant that has left the engine and needs to return when the car cools down or you will have an air pocket. if the coolant is not available to draw back in it takes on air. you may have an air pocket now and thats why its over heating.

well i purged the system. so i pretty much took the air out. but then my friend that was holding the hose did tell me it has a lil suction very little. so i guess i kept on gettin air into it. but with out the tank and if the thermostate is the problem will i be able to drive atleast 30 miles without that tank. my school is that far and i need to get it home because once i get the tank it will take me 5 min to install it.

yeah you could drive it 30 miles but you would have to refill the radiator again before you drove it again.

Hey nistech.I found out why the car was overheating. Whoever installed the thermostate before i got it. is an idiot. He installed it backwords. So the thermostate wasnt getting a reading to open or anything.KNow i have to finish tighteningthe bolts put the overflow thank which i bought i at discount and then hood and take it for a drive.But i have to figure out whats up with the dashboard lights.

I spoke to the old owner of the car and he told me it never usto happen when the car was running it started to happen when the mechanic that had his hands in there before me touched everything. Once he touched everything its had that problem.

I checked all the wireharness and everythign is connected and grounded.Is there anyground in the motor that i cant see. you have to search for them. any ground that arnt on the wireharness.ThanksalexP.S. the mechanic never whent into the car. so he did not mess with the dashoboard wireharness.

Well I have given your problem much thought over the last week[long drive to work...lol] As I though about how that circuit operates. each bulb receives its ground individually with the excteption of a few that get activated by the bulb check relay. so for all them to be on all the time seems nearly impossible. so I have a question about your situation. once the car is running your doors are closed, seat belt buckled ,e-brake released, and your brake master cyl full. are all the same lights lit even when driving as when the car is off and the key is out of the ignition??

Nope when the car is on the lights shut off. But when i take the key out there on. And actually sometimes when the car is on the lights stay on but i have no completly checked with the door closed and seatbelt and stuff. i think they shut off cause i dont rmeber them being on. but then theres times that they are. But i really havent checked like u said with the doors closed and stuff.

I do rember that when i was driving to check if it would over heat the lights would shut off. but i do rmeber when the door would be open lights would be on.and when i would shut the car off and take the key out lights would be on.

that sounds like an ignition switch problem more then anything. as if the ignition switch is making contact still. can you turn the radio on or anything? [when the key is out]

try disconnecting the big connector going to your ignition switch and see if all those lights go out. if they do your ignition switch is shot. It appears this circuit power source is supplied by the ignition switch exclusively when it is turned on. so if it is still getting power when the key is shut off its likely the switch is bad internally.

pull the panel off below the sterring coloum and the lower coloum cover. the ignition switch is what you put your key in to start the car. once you get the covers off. on the other end of where you put the key is a group of wires that come off the switch. follow that group of wires down to the edge of the dash below the coloum. there should be a large 6 pin white connector in that area the wires go into. unplug that connector. if the lights go out your ignition switch is your problem. You can purchase just the electrical portion without the key section. you may be able to look it up through pinnacles parts info and order it. Its cheaper to buy it online.
