Problem with flasher 2003 S60
 

I have a 2003 S60 and as of two weeks ago the flasher indicator comes and goes. Sometimes it works and some times it doesn't and when it does it stops after a few second. I went to the dealership to buy a relay and I was told this model does not have a flasher relay. They suggested having it checked by the maintenance people which typically costs over 200 dollars for a check up of any kind.
So before I have to pay 200 to figure out I have to change a 10 dollars item I want to ask if anybody else had a similar problem. And what did you do about it?
thanks in advance.
