I have a 1991 300D 2.5 and while I was driving with the A/C on, the fan just quit all together. The A/C compressor is engaging, the fuse is not blown, but the fan does not work. I found the following post and was wondering where this part is located and if anyone else has any other suggestions. The fan will not work in the heat position as well.

Climate control fan stopped working (1990 420 SEL)

I just double checked my fuse box and at the very bottom a few lines below the information for the last fuse it says, "AC BLOWER MOTOR FUSE-OUTSIDE BOX".

I think this is what I am looking for, but I can not find it.

Here are two more links, but I can not find it:

blower motor fuse location

location of fuse for blower mtr on 190 2.3 88

It's in a black plastic box which attaches to the left strut tower under the hood, just in front of the fuse box. You pinch the cover and it will swing open. It's about the size of a thumb, you'll see the wire going into it on each side also. It's a metal strip fuse inside of it.

THANKS!!!!!!!!
The metal strip had a hairline crack in it

That'd do it!
Look carefully on the strip fuse, the amp rating is etched/stamped into it, or look on the fuse chart for the correct rating. Should be able to find the strip fuse at lot's of different places.
