I have a 2003 E500 and when I run the ac, the fan blows at the various settings but the volume of air coming from the vents is quite low. I run it full blast and even run it on recirculate but it can't cool the car down.

AC is charged up and no codes. I even tried replacing the A/C resistor under the dash, twice, but no help. One odd thing will happen, after running it for a while, the passenger side windshield will condensate on the inside near the defrost vent in the top of the dash. Could I have a duct off, or are my deflectors not directing the air correctly? Anyone else have this problem?

Thanks in advance for your assistance.

Sounds like your blower motor regulator.

Thanks for the reply. I thought that too, but when I crank up the fan to max, it sounds like it's blowing hard, it just seems like the air isn't getting to the vents, like it's blocked. Could it be like an actuator or motor that works the blend door on the a/c box maybe?

I'm kinda hoping my other gremlins keep the car parked until the hot TX weather goes away around Christmas.

You check the cabin filters? Some W211s have 3, 2 in the dash, and one under the hood.
