The fan motor went out on my 740 about 4 months ago which I replaced. When I took the blower off I noticed it was full of water. After replacing the blower, which has worked fine until today, I noticed my floorboards on the passenger would be wet ever now and then. Today I turn the a/c on and no blower. I guess it is full of water again. Could this be a bad heater core? I don't seem to be losing any AF. I would appraciate any help before I put another blower on.

Thanks.
