I have 2018,19 BB buses and it states relay 19 and 20 for the rear heater motors just right of FB2 (fuse block 2) not sure if they are the same but on my BB buses all relays have a tag stating what it is for on the wires to it

Sadly, just because it doesn't say its for a heater, doesn't mean it isn't. I have a bird here that says "Warning Light Override" but it's something to do with the emergency exit buzzer. Stuff like this makes troubleshooting OH SO FUN.
