(T) Indicators not working properly

Hi guys, Have a 99 Punto sporting. Sometimes when I put on the indicator it won't work. I'll then try to put it on a few minutes latter and it works no prob. Anyone any ideas as to what this is? Is it expensive to fix? Thanks!!

Either dodgy stalk contacts, a bad earth, or a faulty flasher unit... my first bet would be the flasher unit.

May be the contact between the flasher unit & its socket(I had this problem) unplug it & plug it in a few times add a squirt of WD40 this worked for me!

My O/S/F indicator cuts out occasionally...I generally just give it some surgically precise thumps it's a dodgy contact for me that I keep meaning to fix before the MOT
