F15 Fuse holder (Blower motor) E320 94

The AC blower on my AC quits working. I suspect the blower motor fuse is bad.
Can anyone tell me the location of the blower motor fuse on '94 E320?

Thanks

.. and use a test lamp on each side of the fuse for a check..they can easily look fine , but have a hairline crack you may over-look....the test lamp will confirm the fuse...

Thanks.
I found the F15 fuse. I checked it and its fine. There is 12 V output on both terminals. With the fuse removed, there is no continuity on the blower. The blower fan still not working. Any idea what's causing the fan not to work?

Behind the brake booster, on the firewall , there is a 3 wire connector.
Red/Blk/Yl.
Here is the test @ that connector:

Key ON
Defrost position

Blk[neg] to Red [pos]=12v.
Blk to Yellow - variable voltage ..from 2-9 v , depending on fan contol setting.

That yellow wire is the trigger wire signal to the blower Regulator.

See what you have at this connector ..if all is well , you have to go to the blower and check for voltage at the RED wire of blower ..That should be 12v w/test to ground. [ always hot]. If yes , then ground the Blu wire at the blower [ just a jumper wire to ground]. If High fan with jumper , you have a bad Regulator..if No fan with jumper , you have a bad blower motor
