Mk2 45/ZS ATC Transistor Pack Repair Kit - JGN000010
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. You can find brand new Heater Blower Motors here: Heater Blower Fan Assembly - JGC100140
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.
We cannot offer refunds if a repair doesn't fix the transistor pack - this service is to be used on the understanding there is a small chance the repair may not be successful.
List price (new pack): Unavailable, second hand are ~£100If this doesn't fix yours, we can investigate the issue further for you - please email email@example.com for details.
Prices for more extensive repair start at £40 (basic work) up to £70 (if multiple components need replacing due to liquid ingress etc).
There is a chance repair won't be possible in which case a small charge will be made for our time. We can also quote for a rebuilt replacement pack if this is the case.
