Dead battery and fans..

[scottnow]

I am having a problem with my '01 X5. It seems to drain the battery completely after approx. 4-5 days. Had it to the dealer and they say they replaced something in the door panels that was causing a parasitic drain, but it is still happening. I am also having 2 problems which may be related. The first is that they said my a/c aux. fan was not functioning correctly. I have noticed a fan on (in engine bay) when I shut the car off... but not too often. The second problem is that every once in a while my interior blower for the HVAC system goes from high to low really fast. Again, this doesn't happen all the time. I have read that the final stage resistor could be a problem of a battery drain. Could these items be related? Already blew 500 at the dealer and no luck.

As well, what is the deal with the sleep mode? I have not tested it but am going to tonight. I have not tested the sleep mode, but the car is draining approx .5 to .6 amps just upon arming and locking. How long should it take to enter into sleep? If it doesn't enter sleep, is that because there is a draw?

Thanks in advance.
