Rear motor & fan, doesn't look like it'll go straight in the front, but I'm sure with a bit of firkling it could do the job, bonus being, it lives inside the bongo & is not exposed to all the moisture the front one is, doesn't tend to get used as much either, so, if it can be made to fit, it'd be a reasonable source of good fan motors for the front from scrappers or converters.
Rear heater control module, slightly different code on it but it looked the same size & has the same 3 pin connection, so I tried it, works fine on all speeds

The actuators for mode & heater flaps look to be the same too (2 of them in the rear)

The only thing that may be different is the spindle bits that clip onto the actuators, but they just clip out.
I haven't checked to see if any of the rods & clips are the same yet.
There were a couple of relays in there too, I think at least one of them looks very similar to the ones for the lights on the inside of the passenger wing & were rated the same ( I took these off ages ago, I've forgotten details).
