Fan noise when A/C is on........
Car is making a clicking noise from one of the fans when A/C is on. Turn off A/C and noise disappears. I popped the hood and its the right small fan when facing the car. I was hoping someone would have had this issue before and could give some insight. Im thinking that I could replace that fan blade and that should fix it. Anyone else have insight. I think its this fan. The single one.

Sounds like your AUX fan, in front of the rad....?
The drivers side fan is the drive motor and the left side is a slave. Check for debris or deformed cowlings first.

Regarding the OP's fan issue---take the protective screen off and slowly turn one side, as both will turn and determine if one of the blades is hitting the rim---then correct.
FYI The aux fan only comes on when you exceed refrig and coolant temp---do you have an issue with either or do you have a faulty temp sensor??![EEK!](https://mbworld.org/forums/images/smilies/eek.gif)
FYI The right side blower and fan is 000 540 17 88, however the left is not sold separately, that assembly part number is 001 500 39 93![EEK!](https://mbworld.org/forums/images/smilies/eek.gif)
You may be better of visiting any scrap yard
