Repairing Climate Control Unit - Carlo Di Giusto's Climate Control Unit failed when a servo motor stuck and burnt out a control chip. Rather than by an expensive replacement he sent it off to an Italian Automotive Electronic repair shop.  For 200 Euro they replace a chip and returned a working unit. Here is Carlo's report.
 

Bypassing your Heater Motor - Up until the mid-70's, 911's took their primary heater air source directly from the air used to cool the cylinders, and Turbo's continued this practice into the 90's. From the mid-70's on, non-Turbo 911's have used an auxiliary motor in the upper left corner of the engine compartment to provide heater air. This provides a more consistent source of air, especially when stopped in traffic, as it's volume is not engine-speed dependant. 964's continued with an auxiliary motor for it's heater air source, however, Porsche eliminated the auxiliary motor from it's racers, substituting a bypass pipe. By retrofitting the bypass pipe, you remove the weight of the fan motor, maybe 5 lbs worth, and you open up the left side of the engine compartment. Bill Gregory shows you how.
