it's probably due to a loose connection on your ballast resistor.
remove the black plastic fascia on the firewall. take off the outer cover
of the blower motor. right under the center of the motor, you'll find
a resistor pack about the size of a book of matches. yank it out,
scrape it clean, spray on wd-40, and pop it back in. i'll bet it will
cure your problem.
i discovered this on my '85 325e only after i'd already removed the
whole blower assembly looking for the resistor pack. it was getting
dark, so whilst reinstalling the motor, i broke some fins off the fan,
and now it's roached...vibrates my whole dash now and blows the fuse.
time for a new blower...sheesh...anyone got a working one to sell
