Hey Guys
I just bought everyhting that i needed to do a power window conversion, and i have only installed the front driver side so far....

the door loom came from a 02 VRX (AFAIK), i installed everything, and everything is working but the only thing that isnt working is the courtesy light on the loom, i have tried everything i can but i just cannot get it to work..

so idea guys?

Thank in advance!

I am here!!!!

SO you are talking the light in the actual door? If so you will need to make sure you have the correct door switch with 2 pins as some of the non power window models had a single contact switch.

Also, dumb qestion, it does have a globe in it lol?

The door light only comes on with a particular door when it is open, ie DR door open DR light on

okay so your talking about the button thingo so the car can tell that you opened the door?

and if so ill go check haha


what happenes if it only has the one wire?

okay just checked the door sensor and it has two wires.. so??? haha what now?

okay guys i still cant figure this out.. and i dont really wanna run my own wiring..

seems like you'll have to run a wire from the door switch to the light
this should work but may be wrong, find the negative on the door switch, cut wire then solder on some new wire to run to the positive on the door light, the ground light to the door
like i said i may be wrong

This may sound dumb but have you check t se eif the globe is still alive...?? May be blown.

okay guys! i have just installed the front left P/window and the courtesy light Does work.. but the driver side still doesnt work....


ANY idea at all guys?!?!?!

Have you put the connector on the right way?

Have you got access to a multimeter?

yes? there isnt a connector...

and no, but i have one of those test light thingos

Sorry thought there must be a connector on the light itself, didnt think they would have it hard wired?

Anywho....this is where Multimeters come in handy, even the el-cheapo one's.

I'd check for power at the relay/distribution side (if there is one for the courtesy lights?), check for power at the bulb side, then depending on what you find start chasing the fault.

well the coutesy light only comes on when that door is opened.. not any of the others so i know that it is somewhere between the switch (the door sensor) and the light.. just dont know where to start

Well if your normal light (roof mounted) comes on when you open the door, its unlikely to be the switch - im assuming they work off the same switch.

Whippy

yes i believe so...


so i think~~~ there is something missing in my wiring as my car is only an EXEC and i had to wire the RHR power window myself.. but all the other looms were there


Hmmmm GUYS HELP? haha

I doubt anything is missing, if your pass side one is working.

You should have the following

Power constant
Earth only when drivers door open

Swap the door switch from lh to rh to see if dicky switch
You may have a broken wire in the door loom.

You mention is an exec?? Should not really matter as I think the TJ have the wiring for all the goodies regardless of the series

Found that one of the door switches on my TJII was corroded inside.

Unscrew the dodgy switch, unplug, tape the wiring on the body.
Then it is quite easy to take the switch apart.
Clean the contacts and then give it a go.

see im not sure that mine had all the 'goodies' as i did have to wire up my RHR window manually as the wirting weasnt there for it.. but all the other wiring is there for the other doors...

and ill swap the switch over to see if it is the switch this arvo..

EDIT: i know that there are two wires coming from the switch and i was wondering what one goes to the door?

ill also try this if it turns out that the switch is okay.. but ill probably just get one from the wrecker for like 2 bucks haha

Thanks guys ill let you know how i go this evening

okay well i just went out and tested it.. i swapped the two switches over.. nothing..then i tested the two wires
the green wire is an earth that obviously tells the car that the door is open
and then i have the yellow wire that has nothing coming from it.. theres no power coming from it and from what i can tell it isnt earthing anything



cheers in advance

So, we have tested the switch and found an earth wire and a "dead" wire - are these the wires at the switch, or at the courtesy light?
From Mal's post above, you need an earth and constant 12v power.

If the yellow light is "dead" at the courtesy light location, trace it back through loom to junction-blocks etc if you can - making sure that a mating wire is presnt on other side of any junctions. Wiring diagrams from Workshop manual PDF's should assist with colours, locations of wire/pin in junctions etc.

Check also from wiring diagrams what fuse supplies those courtesy lamps, and check that (again, if necessary). Use a test lamp or multimeter if you have these - if you want to test a wire for presence of power, you can use a sewing pin thru the insulation (of just that one wire) and connect multimeter of test lamp to that (not a real "kosher" way of doing it, but can get you out of a bind. Be VERY careful not to pierce more than one wires insulation doing this, or you WILL create extra work).

Tracing electrical gremlins tends to be easier on the car, than conducted over the Net. Tho things like this tend to "do my head in", try to attack it sytematically and methodically (just like I am not managing on my own car, keep blowing fuse #7 since a car-kit went in).

okay well aas i said before i DONT have a constant 12v at the RHF switch but i DO at the LHF. i also have a earth on both...

i find the manuals really hard to read and i cant figure out what plug/pin the RHF door switch connects to

I also have NO power at the RHF courtesy light.

Thanks and your help is appreciated

Without trying to sound harsh, but if you cant read those manuals and electrical diagrams its going to be extremely hard for anyone here (probably apart from Mal) to simply tell you what you need to do.

Elwyn basically described what you need to do.

Your earth switch works - great.

Your +12V constant (which I presume is the yellow wire) has no +12V.

You need to read that workshop manual, find out at the next pin in the loom that has that yellow wire (which as Elwyn has said may well be a different colour depending on which side of the plug you test). Test for the constant +12V. If its at the plug, but not in the door - you have a broken wire in the loom between that plug and your door.

Basically you continue this until you find the +12V somewhere in the loom, and backtrace the problem from there to the door.

Since you think your car may be missing some wiring - check to make sure the correct fuses / relays are in, it could just be a fuse that is not in place (god willing). As I said previously, never had to look at how these cars are wired so I dont know off the top of my head if it could be a fuse or not.

While it wont be an 'easy' job (especially taking apart part of a loom, or finding the right wire to test) if you want to retain factory wiring you need to track down the problem.

This is the best I can do.

okay well first of all i can read the manuals.. but i just cant figure out what connectors / pins.. everything else i can...

also i was planning to track it down tomorrow.. just to follow the yellow wire up to the RHS loom connector to see if a the 12V constant is there and if it isnt just keep tracing it back... until i hopefully find it




just to confirm that the switch is a positive earthing switch so the positive is supplied to the bulb and then the negative is switched at the door switch... Correct?

Subtle threadmine...

(I bought this loom off Whippy last year as part of a power window conversion)

Just in case you ever wondered why the courtesy light never worked:
The Yellow wire was pretty much just hanging on by a single strand from a splice that an owner before Whippy did.
Noticed it when I took the loom apart after replacing it for my customized one.
