I'm trying to decide if this problem is the relay or the stalk switch. The car is a 2006 S60 T5 FWD.
When I pull back the stalk to turn the high beams on, they activate, but do not stay on when the stalk is released. It seems to me the problem could be either place, but I'm hoping there is a way to definitively identify which part is broken. Low beams operate normally.
