the little black box

[akinthecat]

How do i identify with relay unit inside the fuse box actually controls the headlamps? I had changed the lightstalk switch and still i need to activate the fog lamp button to use my headlamps.

they come in different colors and several numbers '257', '357', with bosch stamped over them.

sorry., i don't have the bentley manual to do this...

Your light switch is on a stalk? I don't know if this will help, the '99 and/or the 320i may be different and are not specifically covered in the Bentley.

Dudesky, i got a smaller diagram that's stuck to the inside of the fuse box cover. The fuses are all good, no blown ones. i only removed the fuse for the pesky sunroof. Still my main headlamps are activated by using the fog lamp switch. just wondering what those black relays units do and which ones need to be replaced? How do you tell if you would need to replace a relay unit? I pulled them out and saw that the contacts were bluish (like exposed to high heat). I cleaned them up, and reinstalled them again but still the same results.

The car came with 5.8k xenon bulbs in the main headlamps and regular halogens in the high beams and fog lamps. so the car casts a weird blue/ yellow shade at night. It has never bothered me till i compared my lighting systems with other e36 and wondered why mine seems 'different'.

I seriously don't have to use my fog lamps here as all the street lights in brunei (at least in my area) permits me to just use the headlamps. Its really bright enuf to drive around here.
