need quick help.. int lights & door switches

[suprra_girl]

hey ya'll

interior lights are gone, not sure why... does anyone know which fuse it is? if it is a fuse
what are common failures of complete interior lights?

door open switches, one has failed somewhere, even with all doors closed the dash still says one is open, i'm gonna pull out the front door switches and check them but other than that not really sure what i need to look for

thanks for any help

so noone has ever blown out their interior lights before?

Which interior lights? If you're referring to the Dome lights check the dome fuse and the ground in the dome light housing (common failure point).

 

[jdub]

Check your Dome Fuse...it's in the fuse block in the engine bay next to the EFI fuse.

 

[suprra_girl]

all interior lights are dead, doors, and main int light

dome fuse is good

Checked the dimmer? A dead dimmer is a common point of failure for guage lighting... but I don't think the window switches are on that circuit.

If the dimmer checks out fine:
1) check your ground points
2) Test for continuity of the white w/ black stripe wire going into the dimmer with the chassis
3) Test for +12v on the solid green wire feeding the dimmer, in all three switch positions. Off = 0v, marker = +12v and Full on (headlights) = +12v. If any of these returns something other than listed either the light switch has a bad contact of there's a short in the positive side of the wiring.

digital dash here
guages and glovebox etc work just not main lights

window switches are fine its the door switches for when the door opens and closes that has failed also

thanks for the tips
how would i check the dimmer?
the dash still dims and lightens

 

[CRE]

It's not the dimmer then, so forget I suggested it...

So the marker lights in the end of the door's interior and the dome aren't lighting when the door is opened that's the problem?

Does the vanity mirror and luggage compartment lights work?

 

[suprra_girl]

luggage compartment? boot? or in your guys language trunk?

and WTF do your interior lights have mirrors????

ours are just... 2 lights with one switch and 2 buttons lol

edit: door switches that tell you if doors are open = fixed (bad ground)

 

[jdub]

Yeah...the "boot" and the mirror on the sun visor, passenger side has a light.

 

[jdub]

The reason I ask, the rest of the interior lights are routed through the integration relay #1 (located on junction box #1 - lord only know where it is on your car). The sun visor mirror light and boot light are the only exceptions. I'm suspecting a bad integration relay or the ground it goes to...one is the drivers side switch and the other is the junction box #1 set bolt.

 

[suprra_girl]

our mirrors don't have lights... just mirrors hehe

boot light never worked for some reason, couldn't figure it out, bulb was good but just light doesn't go

at that stage dome/door lights worked

so that bolt in the kickpanel that bolts a fuse type thing on to the bottom of the fusebox is the ground?

From what I can tell on the USDM wiring diagram...yes. The problem is your car is backwards LOL!

You'll need to take a look at the the diagram for your car...I'm thinking it's a ground.

Right - check also the Integration Relay - apparrently, it can go dead, or it might go half dead. With mine - the dome lights dont work but the door lamps do. It's even confusing Jesus.

 

[Finnon]

how come you guys have lights on your vanity mirrors? that would be cool. umust have a whole bunch of stuff we dont have

 

[suprra_girl]

k i'll check that ground down there... it shows on the usdm tewd that the intergration relay is on the back? of the center fuse junction? how on earth do i get to it?

the uk tewd is very similar to jdm so i generally work off that

thanks for the help guys

Ill trade you some USDM mirrors for some turn signals.

Why does everywhere else int he world like our shit,a nd we love theis lol.

 

[suprra_girl]

uk mirrors are pretty much the same as jdm just not elect folding, but here in nz we got the usdm mirrors to be unique, there's only two of us here with them, my mate with pre 89 and me with 89+

 

[Kai]

you have a UK TEWD? Oooh. Got it in PDF?

As for how to get to the Integration relay - erm, i have no clue - its one of those things where you're going to have to strip half the dash off to get to it, and maintain a high level of swearyness
