As title, the cigar lighter socket and door mirrors' motors have stopped working at the same time (i.e. nothing happens anymore when using any 12V appliance in the lighter socket/pressing the switches for the mirrors, respectively). Head unit is still working fine, though.

This obviously leads me to believe that a fuse has simply blown(?). Or could it be a relay?

Can anyone confirm if they are indeed on the same circuit and/or which fuse/s (or whatever) is responsible for the failures.

Car is a MY99 STi 5.

Cheers.

C'mon alcazar or ALi-B... This is your area of expertise, isn't it?....

No-one?

The *** lighter and door mirrors ARE on the same fuse.



That's a Classic fusebox.

Fantastic, just what I wanted to hear. Phew.

Thanks a lot, mate.

On a MY99 "phase 2", is the fusebox behind that little pull down cubby pocket thing, right where driver's right knee would be?

Rescue Dude

Yes, should be.

I think the fusebox pic I put up is on it's side? It'll be obvious when you get the cover off.

Just had a spare moment at work...

It is indeed behind that pocket. Not quite as per that drawing, but the back of the pocket sports a sticker of a plan of what fuses are what and No.4 - yellow 20A - was the one. It was indeed blown bigtime.

I've never seen those mini versions of the Blade-style fuse before... Do Halfords stock them?

Or can anyone post me one?

...S'okay, just reserved a pack of 2 at me local Halfrauds lol.

Okay, so replaced fuse... fired engine... operated mirror switches... nothing!

So checked fuse -- blown again.

So replaced it with a third fuse... turned ign. to "ACC.1" -- fuse still intact.

Moved to "ACC.2" (think this makes all circuits go live?) -- fuse blows.


I'm no sparky but I assume, for whatever reason, as soon as it's switched to "ACC.2" it's getting either a momentary spike of over 20A... Or getting a constant feed of over 20A?

Why is nothing ever straightforward with bloody cars.

Any ideas people?

The fuse's know you're minted John. Cigars indeed.

Possibly a short in one of the many wiring harnesses.

lol

- I only use 'cigar' 'cause that's what the manufacturers always refer to it as. Gay.

- Yeah invariably, Mick. And that 'bothers' me.
But she's going into RCM on Sat morning for them to (hopefully) sort it.

Would imagine it's the cigar/ciggy/*** lighter contacts shorted out and blowing the fuse - easy enough to unplug the connector on the back of the lighter and put a new fuse in and try it.

Cheers, Mick II... er, too.

I sure hope it's gonna be that straightforward.

Do you get access to the back of the lighter socket by removing the ashtray?

Update.

It's all fixed.

Matt @ RCM found the fault...

My car has this strange thing from Subaru - 'POWER CONTENT' - fitted. (I think it must have been an optional extra that the original Japan-based owner must've spec'd).

It seems to be some kind of peripheral electrical thing to plug something into, as there's a strange electrical socket on the panel where the handbrake is, with said 'POWER CONTENT' written on a flip-up cover.

I don't use it at all, as I don't ultimately know what it's for. Anyone know?

Anyway, Matt tested its circuit both open and closed; when connected up, it was shorting and blowing the lighter/mirrors fuse.

So I had Matt just simply disconnect it and tape up the free ends. That way, a future owner, should they want to, can easily reconnect it (and attempt to trace the fault).
