Mk2 45/ZS ATC Transistor Pack Repair Kit JGN000010 / Diavia 133000/3 and 133000/2
Repair kits in stock.
We've all heard of the problems with the Mk2 45/ZS ATC transistor packs - if you're reading this the chances are you're faced with the task of finding a new unit or having yours repaired.
Please note - failure is usually due to the Heater Blower Motor starting to seize or worn brushes within the motor.
The transistor pack can usually be repaired - it's the MOSFET transistors that usually fail. Luckily they're much cheaper than a new full unit!
The MOSFETs supplied are highly-rated automotive specification units, designed to last and handle more power than the original part.
Unfortunately the IC controlling the transistor pack can also fail - if this is the case you'll need a new pack or it'll need extensive reworking. The general consensus is that the transistors are usually the point of failure, meaning attempting a repair is usually very much worthwhile as a first port of call.
