Default Clicking sound under dash only when headlights are on !

2000 WJ 4.0 I6 with 82000 miles.

Noticed recently that I can hear an almost continuous clicking & whirring sound from under the dash but only when the headlights are on.
Sounds like a relay performing a series of clicks & whirring sound in a repeating cycle.

Any ideas what it could be ?

check into your BCM... I just learned about it the other day. Its like a PCM but its for your interior electronics. I was told if I want my interior lights working again Ill have to get a new BCM and rip apart part of my dash. I got other things to be fixing right now so I havnt gave this issue much mind lately

Relays click like that when they aren't getting enough voltage to hold the relay coil on. Suspect a corroded connection in the headlight circuit
