Opel Corsa Indicator problem

I have a problem with my Corsa.

When I stop car and pull out key, the indicators (all three) on one side stay on. Not flashing, simply the orange light is illuminated.

I have to lock/unlock several times for them to go off.

Any ideas as to why, and more importantly, can I fix ti myself?

Sounds like a dodgy relay to me should be cheap.

If you can find the one for the indicators then they normally just pull out of a base, there may be 2 of the same type for one for each side you could try swapping the relays see if the problem switches sides, this will prove it.

What are these and where would I find them - are they near the fuse box?

Normally small plastice box that will pul off a base. As mentioned in the posts above turn on ignition power leaving the engine off turn on the indicator and you be able to hear it and chase it down.

They also confirm one for each side so you can diagnose as I mentioned above.
