Heater Control Unit MK2
Discussion
Hello everybody,
As I have some Problems with the heater stepper motor on my left hand drive Tuscan MK2 I got me a new motor but the problem wasn't solved by that. It's doing the same buls
t as the old stepper motor. The motor gear is just twisting around with high frequency, like some oscillating movement. Therefore I assume the problems result in a faulty heater control unit. So I decided to get it out and give it away to get it repaired. Now I'm just about driving nuts because I can not find this dammned controlunit. I allready have turned all the footwells upside down, ripped off the carpets everywhere in the footwells and even searched with a stethoscope camera without any success. The only thing I found was a heater amplifire and my last hope is that this item is the same as the so called Heater ECU, even it looks totaly different to the Heater ECU's I found on pictures in the Web of MK1 Heater Ecu's. I hope somebody can help me.
Regards
Carsten

Thanks Martin
This makes my day. The unit on youre Photos looks exactly as the so called "Heater Amplifire" I found in the footwell of my Tuscan. It is like you assume. The Tuscan MK2 seems to have a differnt controling unit than the MK1 and it is obvisiosly the same as in all other Models later 2004. I just wonder why the designation had to be changed from "Heater ECU" respectively "Heater Control Unit" to "Heater Anplifire". This has taken me about 5 hours of creeping around in the footwell. But finally it is good that I know it now, so I hope getting the problems with my haeting under controll. I will let you know if this funny gear dancing raealy is a result of a defect in the control unit.

Carsten,
Problems on this part are caused by the excessive heat. On the one hand, contacts on the plug get burnt. On the other hand, the electrolytic capacitors eventually give up.
Here I have discussed this in the German forum:
