Ok, a few weeks ago I posted that my wing mirror connections (plugs and sockets) were different. I was told that this was normal, the wing mirrors are from a later model. Lucky me.

 

Both mirrors and car are JDM. The mirrors are heated folding type, the car is earlier spec and I don't think it supports heated mirrors (though can't confirm), as I have 2 pins less on the car side of the connector.

 

 

 

So, I realised that the larger plug on the wing mirror side was the same as the car side, with the an extended 2 pin section (probably for heat).

 

The old socket and the 'new' socket wiring colours and location are exactly the same. The only difference was a keyed bit - a little plastic lug in the middle, so I cut this out, and it connected fine, same colour and location as they were in the original connections, all colours lined up if this makes sense -

 

NOTE - The connector on the left of the pic is from the original wing mirror loom, it isn't connected to anything. Just incase you're thinking 'why doesn't he connect the correct one!'.

The problem is, nothing happened, the fold/unfold switch does nothing, the mirror adjust does nothing. I got a multimeter out and checked what was happening at at the socket (car side obviously), this is what I discovered -

 

 

NOTE - I'm not sure what's fold/unfold, as my switch is too badly worn and I can't remember which way unfolds/folds on the rocker switch. Also - no down adjust?!

 

 

I've even used the original wing mirror connector (from the original door loom), connected it to the wing mirror side, and tried ALL the wires with the (car side) connector, but not a thing -

 

 

 

I know the power is getting to the connection, but the wing mirrors don't do anything - no mirror adjust, no folding nothing - not a sign of anything on either mirror.

 

I considered that the earth, or negative was on one of the 2 unconnected pins (mirror side), so I tried earthing these. Nothing...

 

I tried an independent 12v (13v actually...) supply to the various mirror pins, expecting a motor to twitch or move...something.....but not one pin did anything on either mirror.

 

So, what have I learnt - I know the power is getting to the connector plug (car side), I know the control hat/rocker switch is ok. Both mirrors used to work fine, though haven't been used in a number of years but have been in box in the shed dry and safe until painting recently.

 

I can't believe that both mirrors have failed in both folding functions and mirror adjust, I mean what are the odds! My best theory is that the mirrors aren't earthed somehow, and so that's why nothings happening at all. The wing mirrors are currently attached to the car, so should be earthed through conact with the door? I can't open up the wing mirrors to see what's going on inside as the screw in the bottom wont come out, and just deforms if I put any pressure on them, they're not in a good way.

 

The mirrors are just dead to the world.

 

So...any help on this one would be most appreciated, as I'm at a total loss!

It's hard to follow what you've done with just a quick read but you are correct 5 wires is everything but the heated part and therefore is the other two making seven which you could put in from the HRW switch.

 

Mine as seven at the female and when i first got the car a 5 wire mirror was fitted so no heated - i put it in actually but now i have proper 7 wired mirrors.

 

I also had an issue a month or so ago when the fuse kept popping, i do have a after market mirror closing module so this was under investigation and for a while i was frustrated but it turned out a sheath had chaffed on the body, so every time i tried to fold it would blow.

 

You say you do have power but does that rule out fuse which you fail to mention, sometime sleep on things and first cover the basics !!

 

EDIT:Oh and don't assume that all the wiring colours match through - these things are set to test us.

Cheers,

 

The independent 12v I tested bypassed all the fuses, plus I was getting power to the connector that connects to the wing mirror, so I knew it couldn't be a fuse.

 

The problem has to be inside the mirror. I just can't believe both are affected. I'm assuming there's an earth that connects to the mirror chassis inside, which in turn earths the mirrors once bolted to the door? There isn't a negative at the connector.

I just can't believe both are affected.

 

This is incredibly unlikely that both mirrors have failed in every aspect.

 

I'm not sure on the grounding issue but again for both to lose theirs - just doesn't make sense.

If you take a look at the FSM pages I've attached here you will see for the mirror motors (bf-61) and mirror heaters (el-69) that no

chassis grounding in the doors is shown to complete the circuits. The +ve and ground is swapped for the motors up/down and left/right

operation through the loom connectors D4 and D104. The heater circuits likewise powered +12v and ground through the same connectors.

Thanks for these, I've printed them and will go through them, see if I can work anything out. Didn't get around to the mirrors today, painted my bumper and wired my passenger seat electrics instead. :)

I'm not sure where all the wiring goes I do remember something like this happening on an Evo a mate had.

 

Turns out the door has got smashed, and someone had used a door from an earlier model with slightly different wiring, so mirror wouldn't work.

 

Probablhy totally different to the case here, but just made me remember that lol.

 

Sorry I can't help other than post a random story :)

Well - anythings possible at this point!! :)

I know i've messed with the mirror a few times in the past Graham but i don't even remember doing that :surrender:.

I didn't have very much time today, but did check the colours from the link you posted.

 

"Orange connects to Green/Black

Blue to Blue/Orange

Yellow to Blue/Black

Purple to Blue

Pink to Green/Red

Black to Yellow/Blue

Black to Blue/White"

 

All my colours matched exactly.

 

I removed the drivers wing mirror and tried to take it apart, but no luck, I've tried using my dremel on the screw, and I was going to use a oscillating tool, but even the smallest blade is going to ruin the mirror casing. I do want to get into the mirror. Really, everything I've done, and all the advice I've been given (thanks all :) )suggests the mirrors should be working, or at least doing something!! The quest continues.

If the case wont come apart easily try pulling the mirror glass off, they are held on by lugs, then you can get some access to the inside screws to take apart

Before you pull the mirrors apart have you tried applying *both* +12v and ground to the appropriate coloured wires?

 

These are the wiring colours and functions of the wires in the jdm mirrors themselves and are not shown in the FSM.

 

 

Mirror angle motor = Yellow, Violet, Blue

 

Heated mirror = Black, Black

 

Folding Motor = Orange, Pink

Thanks Andrew G, your post made me realise there's little point in opening up my mirrors - there isn't anything in there that's likely to be the problem.

 

I thought about what you said, about wiring both positive and earth, and I thought no I actually haven't done that, but everything was positive 12v (depending on the hat switch etc...), I had no earth, that's what I thought the problem was.

 

Then it 'clicked'! I'd like to say it was at this point I designed the flux capacitor, which is what makes time-travel possible, but no... I had accidentally wired my passenger seat motor up backwards just the other day, so the the controls on the seat were reversed - and that's what makes the wing mirror motors work - swapping from positive the negative voltage.

 

I wired myself up a 12v and a negative. Sure enough, swapping the positive and negative would reverse the motor. So now I just need to play with the wires, work out what goes where, I looks like the blue wire is the 'common' if that the best thing to call it.

 

The thing is with the folding option. I couldn't get the mirror to unfold, no motor noises, nothing, I tried applying 12v (or -12v) and one way it didn't seem to like it (on either mirror), it sparked a little, like it wasn't right.

 

On checking the connector pins for the folding (car side) with a multi-meter; it switches from -12v to +12v when switching the rocker, 0v is the middle. So I think everything checks out as I see it. For some reason, I think if I wire the mirrors up, they will fold / unfold - despite not doing anything when I applied power 'manually'. If they don't a fuse will blow - hopefully, I don't need things melting.

 

So things are progressing slowly.

 

Couldn't do it without everyone's help. I'll keep you updated on how thing work out, tomorrow, hopefully.

So, I know we're tired of this thread, at least I am!

 

This is how the wiring goes should this happen to anyone in the future -

 

 

Annoyingly, the wires all match!! (Minus the heated mirror wired obviously) I finally realised that one pin on the smaller plug was slightly offset and not connecting (I should have noticed this before!!), so really, the only wire I needed to re-wire was the one wire -

 

 

 

 

Now, the two wires to right are for the folding motor, and these are the voltage readings going to the the motors -

 

 

Thing is, neither fold. I have to conclude that there is something up with the motors that do the folding, as they won't work. I ever temporarily wired the wires for folding into to the mirror adjust motors, just to see what would happen, and as expected the mirror moved back and forth when I toggled the rocker switch for folding. So everything suggests the mirror folding motors are somehow both dead, or not getting power at their end (as I can't open the mirrors I can't test that side).

 

I will look at replacement mirrors in the future...can't / won't deal with it now. I have a reacting paint job to worry about.

 

Thanks everyone for your help with this, it's finally over, sort of. :)
