My wife's 2005 TL has been having intermittent issues with both low beams not working for a few months. They either both work or both don't work. High beams and running lights always work.
Did a bunch of googling, stumbled across threads suggesting the headlight lowbeam relay may be failing. This diagram seems to support this as a possible culprit:
I opened up the exterior fuse box and saw the fuses mentioned in this diagram and some relays, but not the headlight relays. Where are they? One thing I read said they're not serviceable which sounds odd. Is this true?
Can't get this to fail when I want it to so can't off more info. It's working fine right now.
