I bet it's a bad ballast, but you need to pull the light completely out of the car to replace that. Or maybe the original ballast is missing or just disconnected? Like Dackelone saide, the PO likely swapped to an LED AE set up, which has it's own ballasts installed inside the headlamp housing (rather than underneath the headlamp like the much larger OEM ballast). I think that's what that pink/purple thing is - wonder where the PO got that from? I'm not super-familiar with the aftermarket headlamp "upgrades," but I've never seen any that looked like that.

Anyway, another issue I've seen on the boards is that sometimes the LED ballasts interfere with the AHL motor operation, since there's not really enough room for them in the headlamp to begin with, and the break things that way.

I hope you got a good discount from the PO for all this mess!

And, now for a shameless plug: if you do end up needing new headlamps, I've got a (pre-LCI) set for sale cheap in the classifieds section.

Good luck!
