A/C Control Module - Anyone know anything about it?

[m2500tvr]

Recently, having to remove the fuse/relay blocks from the footwell of my 280i, seeing that the A/C control module box is conveniently clasped and hinged for easy opening, I opened it and found a couple of fried diodes and a fried resistor. This would explain why my A/C doesn't work.

This is a VERY simple circuit board. I could easily fix it if I new the value of the roasted resistor.

Anyone have a schematic? Or one handy/out of the car they could look at to identify the parts? Or anyone know where/from whom TVR sourced this control module? Are "generic" control modules available/are there any other options here for a module?

Cheers,
