This seems like it might be the blower motor, but I just wanted to confirm that it is. Also where can I purchase the blower motor online and do I have to get the S Class One. Also I saw the DIY for the early w210, is it the same for the later ones, I have a 01 E320 4matic. Thanks Alot for your Help Guys

to be the problem,all your numbers are spot on of good operating system.
What is happening to make it not work.Symptoms?
ohlord
none of the errors you display have any affect on the operation.Just clear them while in error mode by pressing both auto buttons at the same time.
tell us more about how it is operating.

I got into the car and the car was blowing hot air. It was working properly today , but I feel the air isn't as cold as it once was.

How is it "the blower motor " when its still moving the air?

I am unsure of what it could be. I bought some r134 already, do you guys suggest that?

pressure looks fine,your evap temp sensor is reading 32f,Your left side and right side heater cores are down in the 50's.Seems like it is all working fine.Checked your cabin filters lately to see how badly they are plugged with dirt.
Autohausaz.com has them diy on benzworld.org w210 section

Your #7 value is refrigerant pressure in bars and 14 is within normal limits. Adding some might help somewhat, but it's not indicated by your test. I think you should follow the ohlord advice with the cabin filters. Even if that is not the solution, they are probably due anyway.

I took the car out today and the vehicle is blowing out hot air again. I am unsure of what it is. The air is blowing but is coming out at a very slow speed. Both side vents are not working on the vehicle, so I have no idea about what is wrong. Any help would be appreciated.

ohlord

the tests again,make sure the ec light is off.Post the results.

i know squat about HVACs in MBs....but i'm running with this thought that it's
possible to have 'normal' pressure readings...but the lines may have obstruction.
is the AC system vulnerable to some ailment which might cause its own version
of cholestrol et al? can the duovalve suffer duo-failure so that only hot air is
emitted?

are you saying that both side vents havent been working for some time....or
that this is a new thing.

raptor3k

The side vents have stopped working as soon as the the hot air started blowing out instead of the cold air
