Help!!! Mazda electrical guru's (final update)

Hi,

I have a 2002 P5. There is a buzzing noise, a bit like some sort of electrical short circuit buzzing coming from under the dash. It is related to the headlights. It is random but quite frequent. When I turn OFF my lights this buzzing starts. Also, it starts sometimes when I am driving during the day. Also, my headlignts have a very suttle flicker.

I have located the problem. (see picture) It is a small white box directly under the dash. When it is making the noise, it vibrates a bit when I touch it.

Any ideas or do I have to go to the dealer? (my 3/80k warrantee is over ...) No mods have been done to headlights or to anything electrical.

Thanks

M.

allo, ce genre de probleme m'ai deja arrivé. Le son que tu décris est le son classic d'un relais défectueux. Ce n'est pas un court-circuit car sinon ta fuse aurait déja brulé et tu n'aurais plus de lumiere. Trouve le relais défectueux(ce qui me semble etre identifié sur la photo) et change le, ca devrais régler ton probleme.
 
moi aussi je pense que ca vient d'un relay, change le relais pour commencer, c'est pas bin chere, pis tu vas voir apres.
Bonne chance!

Ok .. this is interesting. Before pulling out the relay, I noticed that my fogs were ALWAYS on. So must be the fog relay.

So I pull it out see the pic, and guess what? Everything work 100% like its supposed to work. Fogs, lights, wiper, A/c, fan, indicators, etc. I have been driving around and everthing works fine and of course the noise had stopped. Ill have that relay changed, but I am sort of puzzled. When I turn the fogs on/off it works. Maybe im no electrical specialist, but seems weird to me that there is no impact of having that relay pulled.

T'aurais du aller chez le Dealer si ton char était sous garantie de 3 ans 80 000km. Ça aurait passé sous garantie...
