The flashing dash light is a warning about a failing system, most likely the fuel system. On mine it was the oxygen sensor on the way out. You need to do the diagnosis process with the ECU and this will report back the code that will tell you precisely what's the problem. You'll find the ECU diagnosis procedure here at the 300ZX online factory service manual.
Hope this helps.

Where is the hazard light switch ?


it usually depends on what you are driving some are on the dash some are in the middle of the dash around the radio some are on the searing column. what you are looking for is usually a red button with a triangle on it.

A red light on the dash board


The warning lights should be listed in your owners manual. It could be a warning for one of the gauges, or engine/transmission problems.
They are more common on Toyota Prius.

Indicators not flashing on Audi TT


i believe the audi uses two relays for the turn signals and hazzard lights so it would appear the turn relay has failed. it should be located under the dash near the steer column.... seems to me me they have some shielding under the dash so it may be hard to get to.

You need a new hazard light switch - the relay for the hazards and turn signals is built in. It's $40 or so at a dealership to buy a new one.

HAZARD LIGHTS ON BUT NOT FLASHING, INDICATORS NOT WORKING. IF REMOVE HAZARD FUSE, INDICATORS FLASH AT HIGH RATE. (INTERMITTANT FAULT)


HI,
I have the same problem - it is the relay switch attached to and behind the hazard warning triangle on the dashboard. Pull it all out (gently and replace (£60 ish). The indicators and hazard lights are on the same relay circuit. This is a well known problem for this car (amongst others - how about the wipers sticking)

Flashing Unit for Indicators Replacement


Most likely it's the hazard switch - the relay for the hazards and the turn signals is built into it. When they start to die, you will see erratic behavior with the turn signals and/or hazards, and eventually they'll both fail completely. Replace your hazard switch on the dash and you'll be good to go.
