Not at all sure if apparatus box is the correct name - parts guy at German Auto Parts pulled that name from his system. Anyway, it is the large plastic box next to the battery - has all of the cars ecu's in it. It also has a small squirrel cage fan that pulls air from the cockpit and over the ecu's. Mice chewed the wires right next to the motor which means I have to pull the sucker out. I've done this on my personal XFire years ago and my recollection is it came right out with no issues. This car is fighting me.

The motor is loose, but the duct that connects it to the interior keeps it from coming out. I cannot see how to remove that plastic duct.

I have searched this forum with no luck - most likely since I can't come up with the correct name of the thing. I also need the Bosch part number as the last time it was 1/3 the price of the MB branded part. The mercedes part number is 170.545.0095 for the blower motor.

Any tips or guidance appreciated. In addition to this forum, I have searched my 3 volume set of Factory Repair manuals and cannot find any reference to this part. Of course they show in LARGE pictures how to remove the top engine cover/air filter assembly!

Cheers all
