Finally fixed heater ECU connector!
Discussion
I have finally fixed my Heater ECU troubles.
After a lot of fiddling about I found my issue (only the heater blower fan not working) was simply due to one loose connector on the blower fan pin of the connector that attaches to the heater ECU. Is it posible that the pin could "erode" if it arcs? It was apparent the female connector in the plastic plug was moving in and out by several millimetres.
Anyway I could get the blower fan to operate if the passenger held the ecu in one hand and pushed, pulled or twisted the connector very slightly with the other. As soon as they let go it would stop working. Not much use on these cold n frosty mornings when you are driving alone!
I had tried cleaning everything but to no avail. In the end I took the Heater ECU to the local Model shop and purchased a length of brass tube that slid snugly onto the heater ECU blower fan pin. With a Dremel and cutting disc I "parted off" a piece of the tube about 1-2mm long, slipped it over the heater ecu blower fan pin to its base and then pushed the connector back on and now it all works a treat! Took 15 minutes and cost less than a quid.
That was the only apparent fault with my 2000 MK1. The wifes newer Audi TT meanwhile has needed another road spring, 2 new rear discs and pads, 2 more light bulbs and then lost all its water 10 minutes after its service (£580), which meant it needed to be recoverd for the second time this year!

I was following the wife last night(!)and apparently due to the rain, the F'in Audis ABS lights all flashed up (again), so she slowed dramatically (not sure of that logic!) as she joined some dual carriageway and I almost "thrust her in the rear" so to speak. Simple, reliable TVR brakes saved the day!
