A few problems with my e39

[demeter]

hi,last few weeks i've encountered a problem with my aircond fan (at the radiator), sometimes it wont turn off when i removed the key (when that happens i disconnect the fan and reconnect and it's ok), i've changed the fan a few months back (it has a resistor, the previous one does not have).one more thing is the auto-lock function when you drive more then 20 mph, when i reconnect the battery it will work when i 1st drive the car, when i turn it off and drive off again it wont work.i've changed the battery as there was damaged cells in the battery(1 day if dont start the car the battery will be flat).regards,demeter

Hi Brother, if the AC blower going crazy, most likely is bad resistor control causing your problem, before spending the big money, get the FSU from Bavarian Auto, i think it is RM200, and you will likely solve this problem.
