C70 2004 (classic) Heated mirrors /rear window stopped working

[StijnC70]

Now that I found the location, I'm looking for a full description of all these relays (number - function). Some of them have a description on them (like 208: "TIMER RELAY", or "REAR DEFROSTER") but others don't.
I'd like to temporarely remove the beeping relay so that I get rid of the annoying beep while driving telling me that there's something wrong with the soft top (I already know that!). What number is that relay?
