The fan is loud on high speed, and it will wear out , it does not really have a 100% duty cycle on high speed, it normally kicks on and off while running the AC so it does not overheat. Id get the new resistor pack its not that expensive.. Dave __________________ Dave - PDX 1995 318ti - Active Black and Tan. 2005 330xi - Mtech 1 - 6spd - Orient Blue/Black |
