On E32/E34 the aircond blower is controlled by sword. If the sword failed, the symptom can be either blower function only at position4, blower starts even at position0 I talked to naidu, even he confirms tht so far he hasnt found anybody tht can fixed the sword. if the sword failed the solution would be to source replacement sword from chopshop, like moot did. and bav auto didnt even has new sword as stock as its VERY expensive...so i took the faulty sword as moot wanted to throw it away and change few i/c,short resistors etc2... walla... faulty sword now working like a new one :smokin: and it of cos cheaper from the one from the chopshop... :smokin: so who says sword can be repaired ??? any1 tht has faulty sword and interested to have it repair, PM me...:top:
