Right then Boys!!
I HAVE my answer today after spending this after noon at my parents in the company of their S2 T plate 1998 HDi...
I swapped the Air con ECU's over, and mine worked fine in theirs, and the problem remained... so after a bit more head scratching and checking wire continuety my last resort was to try the blower motor itself...
Well HEY PRESTO! It worked!! It performed correctly, adjusting speed through the slider etc etc.. BUT I noticed a difference in the motor..
All the motors I was useing, the blower itself was retained in the housing by RUBBER bunged type feet.... the one in the HDi the motor was secured by 2 screws in the bottom.. so there must be a difference in the motors in some way or another... SO...
Has anyone a BLOWER MOTOR with the 2 screws in the base holding the motor in the housing PLEASE! ?????
Thankyou to Citrojim as useual for his great efforts, and others inc Clogzz who also gave me other pionters to look at...
Regards
Paul
