The fan/blower on my 2001 X5 has become intermittent and/or is not working at all. I had a similar problem last Fall that did not affect normal operation, but was problematic after the ignition was turned off. mooseheadm5 gave me some great advice with that one blower final stage) - could you (or others) help again? Is this the same problem or is there more to it this time? What can I expect in dealer repair costs?
