I can repair all faults associated with the LCD Climate Controller and the electronic Fan controller.
The most common item to fail is the electronic fan controller, officially called "PWM Transistor Pack" but usually referred to as a "Hedgehog".
The original MG-Rover part number for this item is JGN000010, this is no longer available as a new spare part.
The module is manufatured by an Italian company called Bitron for Delphi Diavia, the original part number is 133000/3 CEV/5.
This repair also applies to the same module fitted to some Ferrari models, 360, 430, F430, 456, 550, 575 and ENZO. The Ferrari part number is 064280200.
The usual faults include;
One repair charge covers ANY fault with the "Hedgehog" , the module must be intact and not damaged. Return delivery is included, via Royal Mail Special Delivery for UK customers and International Signed For for customers outside of the UK.
You need to remove the faulty module and send it to me, I do not have this item for sale.
I replace a number of components to increase reliability, extra protection is added and the two power MOSFET transistors are replaced with uprated components designed for motor drive applications rather than the standard IRFZ44N transistors that were originally fitted.
Please be aware that the ONLY reason for failure of the PWM Module is a faulty fan motor which is either drawing excessive current (siezed bearings) or is generating electrical spikes (worn brushes). The fan motor fault MUST be rectified before refitting a repaired module!
If you have a fault with the LCD Controller please contact me for advice and repair costs.
The controller part number is JFC001320.
