Hello 👋 all.
My hubby is trying to sort out the issue we have on our new (to us) 9-3 convertible- 2001.
The previous owner passed away and his wife did tell us that something had been draining the battery but he didn't find the cause. I've read lots of posts on her about the issue but often the symptoms differ a bit from ours.
When the battery is connected a buzzing comes from the centre console around the heater controls. When hubby pushes either side of the control panel, the buzzing changes or slows a bit. He's pulled every fuse and relay and the only thing that stops it is the fuse for high/low beam + acc.
So obviously it's the ACC. Any advice as to what's likely to be causing it behind that panel and what he should renew or clean connections on behind, please?
Thank you very much in advance.

Normal for old temp sensor fan. Runs up to 10min after key off. Pop out acc panel, remove fan unit, blow off dust etc and lube bearings. Reinstall and will be quiet. Done over 100. This unit will not drain the battery, ampmeter in series with battery, pull fuses to determine circuit involved and the unit causing the drain.
