Link shows Jag circuit. I think the BMW does not need a Darlington type tramsistor, just a normal one. Charlie I tried to send you an email question about the Blower motor electronics. Got an error on delivery problem. I need more info on the speed control module inside the blower motor. I appreciate the info you provided in a reply post but I still don't have enough info to fix the problem. If you have any diagrams of the system I sure would appreciate a copy (if anyone else has a clue please post me). This model BMW has poor cabin ventilation without a good working blower system so the problem is one that can't be ignored. Thanks
