LC3 Aircondition Control unit

My LC3 has developed a fault on the Circuit board on the Aircon control unit.

The circuit board is not available on its own, but comes as a sub-unit called
"Heater Control Assy" T55900-6A121, but at a staggering cost of £1500.

Does anybody know of somebody that successfully repair these control
units?

Update to my KDJ120's troubled Air Condition Unit as follows:

The fault that was wrongly diagnosed by Toyota in Worcester as a faulty AirCon Heater Control unit to £1500, but later successfully diagnosed and repaired for roughly £50 by Toyota Nestle, Dornstetten, Germany (just a faulty relay).

In addition Toyota Nestle also managed to get an expert down from Toyota Motor Sport to re-program their Chip in the Performance Kit, so to modify the CPU characteristics to get me more power especially needed at the lower revs when bogged down in fine desert sand.

The mind boggles...

Nice one!
