560SL Weak A/C; Weak Blower

[SRMURP]

Hello,

I have 19886 560SL with 133k miles. I have recently had the Climate Control Unit (Klima Control) replaced. In addition, I have checked the refrigerant and it appears OK.

The issue is as follows, when the A/C is engaged, it only blows a very weak stream of air. To be clear, by engaged I mean:

- Fan speed is on high (i.e., the top of the three fan speed buttons is pressed)
- The temperature control wheel is set to max cold
- The middle of the five fan control settings is pressed.

I do feel cold air coming out, just not strong. Since there is at least some air coming out, perhaps the blower is malfunctioning, but logically it seems it is not completely shot.

In addition, I do hear the compressor kick on and the air is cold, so I think the compressor can be ruled out.

Is it possible that the temperature sensor is bad, causing the fan not to blow hard as it think the cabin is warm already (admittedly, I find this unlikely).

Wondering if anyone has encountered anything similar and if you have any ideas regarding troubleshooting.

Thanks all!
