included is an attachment which points to the fuse.
is this a spare or what? i checked and i cant find this fuse. there are 3 light green ones under it but that fuse is missing!

what specification is this? part number? im going to order one if its important.
are they the black ones under the bonnet?

 

ok, apparently its the alarm relay, and i do not have car alarm. btw, i found out that the built in horn relay is bad, (clicking sound when you press the horn) and now i suspect that another relay near it is blown such as the power steering fan. the fuse box is 200 dollars, is an electrician needed to install it? or can one do it himself? is soldering or wire cutting required?

 

Fusebox replacement is simply by unscrewing the unit and unplugging connectors, according to service instructions. How did you decide that you need a new fusebox (instead of just replacing relays)?

 

rkw, i was searching the forum and i got many members saying when they heard clicking noises when the horn button is pressed means the horn relay is blown.

bad news is i heard the horn relay is built in, ps fan might also be hard wired.

plus, when i replaced the powersteering fan yesterday on a 2002 cooper s, the fan does not spin whenever the hi cooling fan is on (drove around in 80 temp)

so in order to fix this problem im going to try to buy one horn for 40 bux and if that does not work then i will have to replace the fuse box.

 

I thought if you hear clicking when you press the horn switch, that means the relay is working. If you hear the clicking noise from the relay but don't hear the horn, that means something else is not working instead of relay.

Relay is a switch (contact) controlled by an electromagnet. If you hear clicking noise from the relay, that's why the contact inside of the relay moves to other contact. Because of this noise, you can maze an old style buzzer out of a relay.

Just my 2 cents.

 

If you hear clicking, the relay is working properly. The "fuse" you are looking for in your diagram is a relay.

I am willing to bet that both of your horns are blown, also check the fuse, if that is blown, one or both of your horns are shorted.

 

I think the horns may be ins series, so if the first one goes out, the second won't work. On a 04 when I disconnected the left one (facing the car) the right one didn't work, though I can't say it was working before the surgery.

 

One horn will work if the other is blown.

 

yes, both horns dont work. is there anyway to replace the horns without removing the bumper? i see a wide opening that fits my hand. i am thinking about using an L shaped torque wench (dont know if they make that or only hex), plus the horn does not look big.
