Replaced the final stage unit in son's 96 318i and thought I was done except for a new cabin filter change...but now I see something new. I notice the fan in the bottom of the digital heat/cooling control unit keeps running after key is turned off. I can only turn it off by removing fuse #31 or unplugging the digital control. I was told by a fellow in NY that rebuilds the digital units that there is a short elsewhere in his opinon, not a control issue. Has anyone else run across this before? My understanding is that this fan moves air for the climate temperature sensor.
