W124 Newer Style Blower Replacement

I have been reading posts and the guides on how to replace my 1993 W124 Coupe heater blower motor, however my motor is different, (see images with wiper assembly removed).

The unit is encased in a solid plastic housing which is part of the firewall, can anyone tell me how to get it out for replacement?

That is not a normal 124 blower! Even the updated model (with filters) is still a central motor with plastic fans on each end of a long shaft. That looks like a DIY "it'll work" kind of thing....

I've never seen anything like that, and I own two 124s and have been a US MB tech for 20 years. I can tell from the pic that this is a RHD car. What market is this car from?

From the pics it looks like a later model 210 style blower laying on its side. First you'll need to disconnect the harness and pull it and its grommet though the bulkhead. You then should be able to remove the 3 or 4 screws from the brake booster side and take out the motor with the housing. From there you can remove the locating screw and remove the motor from the housing. Shouldn't be too big of a deal, especially if you've managed to disassemble it this far.

That version was one that was available in Europe but never exported to North America.
Remove the electrical connectors and remove the 3 screws that hold the blower. Blower should then slide right out.

Hi, Rick76 is correct. I just looked in EPC and it looks like the part number could be A124 820 01 42 or A124 820 33 42. These are just a guess without having your VIN.
From looking at your picture it does look like 3 screws hold it in from the right side.
I hope this helps.

Yes Rick76 was absolutely right. This is a UK car, pre-facelift registered 1st Sept 1993 320CE.

I found a nice video here, not sure about the audio though.
