Hi all,
As a newbie, I hope you will excuse my very basic question... Where is the main beam relay located?
I have had no main beam on my headlights for a while now, and I really need to fix it.
Bulbs are ok, switch activates the blue lamp on the dashboard display, but no main beam.
Has to be the relay, right...?
X300 3.2 1995.

 

Hopefully just the relay!

No, not necessarily. The switch does not activate the relay directly. The switch is an input to the BCM (Body Control Module). The BCM then switches the relay and the Blue indicator light separately. So there could be an issue with the BCM.

 

Ok chaps, thanks for this. I now know where the relay is! I have quite a few cars, all older and much simpler than the Jag, so all this wiring is rather alien to me!
I'll get to it if it ever stops raining this week...
Curiously, the flash does work; but this seems to operate the dipped beam... I have never had a car that flashes the dipped beam. Is this normal on the X300?

 

I don't think so!
Flashing is just switching the main beam on briefly; sounds like somebody has been at your wiring!
Or it's the relay.

 

That's what I thought...
