Hi there, I have a 99 9-5 which is having problems with the headlights. I already checked the relay and it seems to be in good condition. Checked all the circuits and everything seems to function properly. I am now looking to find what else could be the problem, any ideas on what I should check? Thanks!

Do they just not turn on? Will they turn on to high beam?

Only one of the high beams and only one of the low beams will turn on. These are on opposite sides. I checked the fuses already too.

Try swapping the bulbs from left to right. If the low beam and the high beam still turn on on the same side before the bulb swap than it can be wiring or the socket, if not - just change the bulbs.
