Odd indicators

Got some strange things happening with my indicators. Turn left is fine, all three work. Turn right, front isn't working and side & rear ones run at double speed.

Front bulb looks perfectly good: I will change it but the filament isn't obviously broken.

Tried hazzards, and neither front or side N/S work now. Both are fine when indicating left. [&o]

Might this all be down to the one bulb, or is it a relay problem?
 
Sounds like a classic bulb issue, either the bulb is blown or is not making contact in the holder.
Check that the holder is clean and dry and re-try it.

Mine does this on the left front on occasion, I presume when a bit of moisture gets in
 
Mine did a similar thing, it was the plug in wiring connection from the indicator unit to rest of the loom.

In typical Porsche fashion it can only be reached with figure tips with the indicator unit removed from the front.
No access from the top through the engine bay, so in my case had to take all the under tray off and get to it from there!
The plugs just needed a good shove back togather.
 
Paul it could well be the switch at the end of the stalk itself. Mine started behaving oddly a few years ago but a new S/H stalk unit cured it - around £20 from Promax IIRC

One of my thoughts as well, but how would that fit in with the hazzard switch?

Before I go mad with taking bits apart to no avail, I can't get my head around why the only fault with the indicators is the front bulb when signalling right, and the other two flashing double speed. The fault with the hazzards is the same bulb on the offside, but now the nearside front and side don't flash. These work perfectly well when indicating left? [&:]

Is it more likely to be the relay, or would a somewhere in the wiring or switches cause the two different symptoms?
 
Bulb or wiring to it.
All the other symptoms are likley to be related.
Used to get it all the time on the old Betas

I had similar symptoms once after a particularly heavy rain shower with the car parked nose down on a slope...water had run down the bonnet and into the recess around the indicator lens, then into the bulb mounting causing a local short. Dried that out and it was fine!! A hair dryer did the trick, I recall.

Not much of a seal around where the lens seats into the lamp body, can't remember what I did to improve the seal, but it hasn't recurred.
 
Sounds like an earthing problem.............

AS my dad said after a lifetime in the electricity supply industry.....wine, women....and dirty contacts.....[;)]
 
Paul, there are 2 fuses per side on a 944, 1 for the front and one for the side and back indicators. I had a problem on a car with exactly the same problem, spent a day with much head scratching and connector checking. Always check the easy things first!!!

Thanks Alasdair. Given that this seemed the simplest place to start I checked all the fuses tonight. Removing them all they were fine. I took the opportunity to wiggle the relay as well.

Result? The fault has swapped sides. I now have exactly the same indicators failing to work, but in reverse. [:eek:]

I'll try a new relay, but beyond that it's going to have to go into 944 A&E, electrics aren't my strong point.
 
i have the same prob with mine, rear and side work not the front. it also has the same symptoms with the blip on the alarm and the hazards so i'm led to believe its either the contacts for the bulb, the new bulb is defective or the fuse. it could be the indicator mount itself, so fingers crossed.
its going for a service tomorrow and i've mentioned it to the doods in the garage so see what they find.
