My heater fan is suddenly squeaking something awful, all the time,

before I go crazy from the sound. I would try to lube it, or maybe
put in a used one, but I know from experience with the wiper assembly
(which has to come out on a 124 to get to the blower) that I don't
want to have to do this job more than once. Rusty's web site shows
both Behr and ACM motor/fan assemblies. I've never heard of ACM, but
it's half the price of the Behr unit. Comments?
ACM is NOW a Mercedes supplier (but wasn't in the '80s) of original
equipment parts. I have used several ACM aux. fans with NO problems and
other have reported that the blowers are fine. Some modification to the
blower mounts MAY be necessary (but that can be true with SOME Bosch
blower motors too).
IF there is little or no play in the motor bushings, then lubrication
with ATF can restore function - sometimes for years! Several of mine
have lasted for more than 5 years without return of the noises. If there
is considerable play in the bushing (if it has worn and become egg
shaped) then replace the motor. Check that the fan brushes are not
seriously worn (that has NEVER been a problem for me with 124/201 blower
brushes).
