Hazard lights - Coupe 1995

re your vents the cable connected to the dial that selects blow direction may have come adrift so the lever that turns the flap determining the blow direction wont move. good chunk of dash may have to come out unless you can get to it from behind

Thanks Lofty

I am going to remove the hazard switch today but I recall doing that once before and it made no difference. My garage tried to buy a new haz switch from Audi but they are discontinued. The garage has checked all wiring leading to the indicators and all are in good shape and no sign of shorting.

no problem mate, on that age of vehicle it can ONLY be wiring to hazard switch FULL STOP!!!!!!! if it still does it with switch detached, you know its the wires. the wires could be touching leading to the hazard switch anywhere leading down behind the dash so reach in as far as you can and re adjust it all looking for bare kinked or touching wires.

this diagram will give you a simplistic idea of how it all works, as you can see the only time left and right come together from the indicator switch is from the stalk to the hazard switch, so get the steering column off too and go all the way from the indicator stalk to the hazard switch it Will be there somewhere dude, it will be!

Step one: disconnect hazard switch- go for a drive using indicators as normal.

if the problem still persists:

Step two: examine all wires leading from stalk to hazard switch.

if in step one problem is solved with switch connected source another switch, even if you can find a switch from another vehicle in which wiring is similar might be worth trying that too.

Hope all this has helped its sunday what are you waiting for :-)

Disconnected the haz switch, ran engine. No indicators atall. Changed switch for one I had in the glove box, same fault - hazards or nothing. I'm not electrically minded so I think the car will have to go a specialist to get fixed.

oooh a gremlin. sorry from here im stumped, looks like an auto electrician might be the only answer. well....... i tried :-)

[Lofty79]

just a thought, on that diagram you see the relay for the hazards? if that was stuck open it would have same effect, do the hazards work on theyre own i.e not indicating just hazard button pushed? the hazard flasher unit/relay may be the culprit mate, not quite clutching at straws yet i actually think this may have credance. its just the wires that are left after that.

all my other research i have done indicates (excuse the pun) a bare wire touching the chassis or another wire in the indicator hazard light circuit. Have a go at looking at the wires get some panels off search for crimped wires bare wires anything out of place, it is highly likely a short is happening hence its getting better or worse sometimes when its disturbed.

Haz lights work fine via the switch. Today, the indicators worked fine but on Monday, they didn't !

UPDATE UPDATE

Indicators now working. I took the car to a auto elec specialist and within 3hrs had found the problem. He did explain in very basic terms that there are 5 main wires linked to the indicators although there should be 4. He suspected the 5th was at some point connected to a tow bar or alarm but couldn't tell which. He cut the 5th wire and hey presto, fault gone so it was obviously broken or shorting somewhere between the dash and it's end point. So, £42 well spent I'd say !!

Decision now is to whether to sell or keep the car.

Basic info:

1995 L reg
2 litre 16V
Gun metal
5 new tyres
MOT until May 2012
Tax until November 2011 (I think - will check)
Brand new fuel and brake lines, new discs and pads all round in September 2010 (I drive on average only 90 miles a month sometimes less)
Blaupunkt CD/Radio
Overall very nice condition.

If I decide to sell, and using everyone's expert advice - what price should I go for roughly ??

Cheers for all the elec advice.

The way the market is today, around £600, but to be honest with all the new ,replaced and repaired parts you'd be better off keeping it unless it really has to go
