I have a 97 W210 model Mercedes, the AC is not blowing as cold as it use to, it's blowing cool. the right side seems to get cold before the drivers side but the drivers side evntually cools down. I ran the diagnostic test and came up with these results

sensor1: 27

sensor2: 42

sensor3: 21

sensor4: 17

sensor5: 21

sensor6: 97

sensor7: 13

sensor8: 61

Error code: b1227

Does anyone know the part# for this part?

Do you have any suggestions after reading the values I've posted? I need this AC back up and running fast, I'm in Florida and it's HOT.
