We just replaced all the carpet in my 78 280....i noticed while tappin on the hazzard swich (mounted on console) the signal lights begin to work and the dimmer switch is now working... Is this possible that all these components are linked in someway..

I was going to replace the dimmer switch for the lights and signals.. Now i dont know what to do.. Please help me..

Not sure if it's linked to the dimmer, I have to look that up, but it is linked to the turn signals. A bad flasher switch will cause your turn signals not to work.

The Hazzard switch is definately connected to the turn signals. The hazard switch makes the turn signals flash. If the hazard switch is weak or worn, this will effect the turn signals. Maybe just one of them or even all four corners.

The dimmer switch is ONLY on the dash lights circuit, which is connected to the parking light circuit. The dimmer has NOTHING to do with the rest of the parking light circuit. If the dimmer seams to effect the turn signals, then a related ground is the likely culprit.

A related ground is a ground wire that is used by more than one circuit.

thanks again..does anyone know where to purchase a hazard switch?

Have you checked with your local Nissan dealer yet? That's always my first stop.

thanks arne.. i will call tommorrow.. they seem to have limited amount of parts.. can this switch be taken apart and possibly repaired

thanks again..does anyone know where to purchase a hazard switch?

There are two on ebay right now.

Zs-ondabrain is correct. I had a similar issue in one of my '78's and we traced it to a faulty hazard switch. The circuits are definitely connected. Switched it out and problem solved.

Good luck!

For best results at most Nissan dealers, you should get the club parts CD and look up the part number yourself to take to them. That way you aren't asking the parts guy who doesn't even know what a Datsun is to try to find your part. You'll find that a lot of parts are still available when you do it that way. Sometimes I have to wait a few days for a part to be shipped from Tennessee, but for you that should be quick.

I REMOVED THE HAZARD SWITCH TODAY AND DECICED TO TAKE IT APART JUST FOR FUN.. I FOUND INSIDE CORODED CONTACTS.. I TOOK SANDPAPER AND CLEANED THEM JUST LIKE AN OLD SET OF POINTS.... REPLACED SWITCH AND ALL WORKS NOW....:laugh: 4 TINY SCREWS HOLD THIS SWITCH TOGETHER.. JUST THOUGHT THIS POST MIGHT HELP SOMEONE... THANKS FOR EVERYONES HELP IN DIAGNOSES..
