I need to replace my blower motor and need detailed instructions on
doing so. Anyone have any websites on doing this? I found
http://www.nmia.com/~dgnrg/page_15.htm , but the beginning of the
instructions are vague. I need more info on accessing the panels that
need to be taken off. They look to be in the engine compartment and the
images seem to be taken with the engine removed. Can anyone help to
give better instructions?
It's somewhat hard to point you in the correct direction since you left
out the rather vital information like year/model of your BMW. We realize
that the one you have - that's broken - is the object of your heart -
but it may not be the one WE'RE thinking of.
On most BMW's you basically disassemble the entire car until you get to
the blower motor. Your choice if you want to start at the front of the
car or the back.
I have done this job several times on an e30. The last time it took me less
than 45 minutes to replace the blower motor. I see that you have an e39 so
my experience may not be directly applicable. Access to the blower motor is
provided by a removeable panel on the firewall just in front of the
windshield wipers. The photos in the link you posted all look very useful
to me except the first one. I believe that the overlaid arrows showing the
edges of the access panel are incorrect. On my car the upper edge of the
access panel is hidden under the rubber seal that is installed along the top
edge of the firewall. The seal is not glued on and can easily be lifted up
and off from the edge of the access panel. After you do this, the extent of
the access panel is much more apparent. There are 4 or 5 zipties holding
wireruns and hoses to the front of the access panel. Cut these zipties.
There are 4 or 5 hex head screws through the front side of the access panel
that have to be removed. Then the access panel can be pulled forward and up
to remove it. I believe that the photos that you have will be adequate to
guide you through the rest of the job. Don't forget to replace the zipties
when you get done.
