L322 L322 V8; Clicking noise (like a relay) from passenger side

So... Long story short - My L322 started thinking 'why keep the water outside, when we can just let it in' and in my research as to where this water actually got in I wanted to (semi) remove the headliner.
Not wanted to have power to the airbag while fiddling with the A-pillar I unplugged the battery.
Found out where the leak was (shoddy prior windscreen job) and put everything back to where it was and hooked the battery back up.

I fully expected the car to throw a tantrum at next startup (partly because it reeeally did when I had it at a shop which didn't unplug the battery in the correct manner a while back). And it kind of did - lots of lights on the dash, air suspension fault, and a clicking noise.
Took the car for a ride and everything mended.
Well... Except for the clicking noise.

It sounds like it's coming from the passenger side (my car being LHD) and it almost sounds like the relay for the electric seat on the passenger side.
Which is what I honestly thought it was, as this was the only sort of familiar sound that it lined up to.
I pulled the fuse for the passenger seat, but the clicking persisted. Quite intermittently so, which makes it harder to know from exactly where it stems.

I have no diagnostic tool as of yet (on it, though - just need to pick the correct one) and I fully understand that it's not really possible to give any hints on the matter based on what I'm giving.
But I thought I'd at least try. Someone might have experienced the exact samt thing and fixed it.

This (the leak, and now this) is actually my first kink with the L322. Other than that it's been a very problem-free 9 months of ownership.

I had to use the car today and it started clicking as soon as the ignition went on.
I tried to listen to where it came from, but couldn’t really make it out.
Drove for a bit with the clicking coming and going.
It was coming from somewhere within the cabin, so I tried all the electric gadgetry- sunroof, AC on/off, stereo same, seats, etc.
But then I took the passenger side window down and it stopped immediately.

I remember when I was looking at a P38 and it had a fault with the BCM not thinking all windows were up (they were).

I guess maybe it was something along those lines.

Hevac blend motor its comming from behind the centre vents you can remove them then the motor give it axstrip down and clean refit and your good to go.

Click to expand...

Well…
It has completely vanished since opening and closing the window. It really didn’t seem to come from the center of the console, either.

Bonus when they fix them self's, the hevac blend motor always runs a cycle on opening the door or unlocking it not so sure about the windows
