IF what you are saying is correct in the larger picture... they would have installed the dog and cat and human hairs on the input side of the evaporator at the factory....

also... from the size of the components, I am dubious that anything was DESIGNED on the 123 or 126 ac system... more like cobbled together to appease the stupid americans that think ac is important... germans don't need no stinking ac... why do we?

ha.

it's like mb went... the rich americans need ac to be a luxury car, hey, GM... can you loan us some ac parts? and they stuck in what would fit the grill and made the cabin all fancy and automatic.

look at most american cars... the grill is designed around large condensers. heck, my standard cab pickup has 1/3 the cabin space, but 4 times the condenser space... cools better than any 123 could dream of cooling... massive blower massive airflow... massive condenser... sure it's designed to flood the suction line, and has a built in liquid bucket and a stupid orifice tube instead of a sophisticated TXV... but the thing works very very well.

Kind of true actually.

Back in those days, the Europeans pretty much sucked at three things: Automatic Transmissions, power (windows, seats, sunroof) stuff, and A/C.

None of these were popular in their home markets and they didn't really have much to draw from. A/Ts were sourced from Chrysler and GM, A/C from whomever, power windows and stuff made in Klaus's garage or something. Audi even went to the extend that they tried to solve it by sourcing two key components for their new 5000 from GM: The ACC unit and the power seat bases. Both ironically the highest failure items in that car.

So yeah, the 123 and before had mediocre A/Cs even new, the 201 was a big step forward for M-B in that area as the first design to incorporate A/C from the beginning (and it showed).
