So the time is drawing close to my car being insurable, so I need to make sure she's all working. The fan isn't working though, and I was told it's a fuse. The problem is, I don't want to have to go through every single fuse to find the offending item.

Firstly, where is the fuse box? Is it located somewhere in that rats nest of wires under the glove box?

Second, what size fuse is the fan fuse?

Cheers.

I have an S1.5 and mine is in the rats nest. It's suspended from the wires so the easiest way of getting to it is on your back in the footwell.

The engine fan fuse is the bottom row (row against all the relays) third in from the left. Shown as a 25A fuse in the Bible.

Ahhh, I'm after the interior fan fuse. The one that stops the windscreen misting up (which will be a serious problem in this weather).

Ahhhhhhhhh ok that is second row down, second column in from the left. Its shown as a 30A.

BTW I bought some RainX anti-fog stuff before TiTT4 and the car didn't steam up at all the whole day (well apart from the rear screen which you cant do). Would recommend it. One bottle will do loads of applications but make sure its well ventilated, it's strong stuff!

Many thanks for the replies chaps, and thanks for recommending the RainX; where do I obtain some?

Also, is it a blade-type fuse?

I bought mine (on a whim) from Halfords. I think it was £6 for the bottle. Sure it's not the cheapest but it's easy to get.

this is the point you realise how useful those fuses that light up when they blow are!

Yup. The fan used to work, and cut out shortly after we did some work on the radiator to remove an air lock and flush it. I'm guessing it's purely coincidence, as from what I've been told the air lock can't effect the operation of the interior fan, correct?

Here is a pic of my fusebox (I'm afraid it's upside down, as that's how it's situated at the moment. The innards of the car have fallen out, and I can't shuv them back in). There appears to be a missing fuse, which is what my finger is pointing at.



Sorry about the huge size of the pic. My finger is that fat skin colour object at the bottom of the picture.

looking at the electrical scheme there should be a 15A fuse for the dip beam lamps.
do they work ?

the blower fan is fused with a 15A just below the green 30A (in your picture above the green)
see scheme for details

Hmmm, the knob that has the light on it that is situated above the tape player, doesn't seem to work. Shall I just replace all the fuses?

No, not really. It is easy to see if a fuse has blown or not. Replacing all fuses doesn't cure other wiring/switch/connector problems. Just do a proper fault trace using the diagram and a volt meter.

Thats not the light switch, thats the fog light switch which requires the lights to be on. The lights are on a third stubby stalk behind the wiper stalk to the right of the steering wheel.

I seem to remember that I have a fuse missing too but I'm still at work so can't go look. I'll check tonight and let you know.

Ok chaps, well I've stolen my dad's volt meter, and also bought a big box of fuses, so I'll be sorting it out early next week.

Just to ask a quick fuse related question - which fuse is used to provide power to the cigarette lighter?

The previous owner of my S3 says he removed it but i'm surprised nothing else seems to be affected?

Try your dipped lights cos you should get nothing with that fuse missing...should be a 15A there. Also I forgot to look at my fuses and now the cover is on and its raining so I'll get back to you on that one.

I managed to blow mine by stupidly shorting the contacts with a multimeter probe. Mine was fused through the instrument lighting and warning light fuse.

Check you actually have something plugged into the back though as someone had done something interesting with my warning light wiring so one light had two +ve wires and another had two -ve wires going into it. You never know what's been disconnected.

Changed my lighter recently (old one lit up white while all instruments green) and managed to blow fuse, 7.5A also does n/s side lights.

Just follow the maze from the cigar lighter to the fuse. Line "G"

You end up in the second column, third row. It's a 10A fuse. (also feeds handbrake/low fluid warning light)
