This is for a friends car, the dealer has run out of ideas, anyone think of anything that could cause this. Thanks in advance.

"Hi, I'm wondering if anyone else has had the same problem, or can offer me advice on why my harzard warning lights don't work.
Worked fine a few months ago.

I have a UK model 04 plate 350z GT with 30k miles.

The fuses have been checked in the drivers foot well by a mechanic and the hazard warning switch (near the heated seats button) was repalced by Nissan in Oldham as they thought that could be the problem.

My car is still with Nissan awaitng 'further testing' to locate the problem.

Only problem is - it failed the MOT due to hazards not working! ""
