Does anyone have a tutorial video on how to remove the blower motor housing heater core assembly On an R53? I have the whole dash out, and have already disconnected the heater core. I have already removed the a/c compressor, but still have the lines going into the firewall, I think I need to disconnect the lines from the engine bay in order to be able to remove the blower motor housing heater core assembly, just a guess though. I was hoping to be able to remove the remaining lines once the engine swap takes place next month, but it doesn’t seem I can get the wiring done unless I can remove the blower motor housing heater core assembly

Before anyone asks my what I’m doing, I have gutted my R53 for the track and have removed all the unneeded wiring, minus the remaining wiring behind the assembly.
