Indicator works for a few seconds only

Faulty flasher unit.

Thanks, is that a big job/expensive to replace? I know little about cars I'm afraid.

Cheers for the reply.

My car is a bit like that. I put the indicators on and then they go off and then back on..............

I'll get my coat.

The message from "lost it" contains these words:

Yes it's working, no it's not, yes it's working, no it's not, yes it's working, no it's not, yes it's working, no it's not.....

if it works on one side ok then probably the relay is ok.

operate the hazard switch a few times, it may have a bad connection.

Locate where it is , usually in main fusebox - get someone to turn on indicators and feel which one is ticking, pull out and put in new one. "Shouldn't" be too expensive. Plenty in scrapyards.

This morning it began happening on both sides. I did try using the hazard lights and alltough yesterday they also stopped after a few flashes, this time they kept going and now both indicators work. Any idea what that could be?

Thanks for your reply.

Hazard warning light switch in that case.

The hazard switch should only be used infrequently in normal driving, the contacts become corroded and fail to make contact, often on one side only. Sometimes I have had to flood the switch with wd 40 and operate it a good few times, before the system will work properly. This often only manifests itself just after MoT, when the hazard switch gets tested.

The hazard switch is quite a complicated switch. It can't use the same feed as the hazards as it must work with the ignition off. So it also has to disconnect them from their circuit otherwise indicating while the hazards were on would then switch the ignition on and off...

Of course modern cars may use electronics to do the same thing.

If you can remove the switch, clean it with some switch cleaning fluid - Maplin, etc.
