2003 430 CLK
A/C Blower completely shut off
Hi. My 2003 430 CLK air conditioning is not working properly. It was barely blowing out air, even on Max. Not it doesn't blow any air at all, and the EC button is on permanently.
Thanks to your combined brilliance on these forums, I just ran diagnostics.

Yesterday, I did change the air filter, and I pulled the regulator and the blower. I cleaned them, and pulled off the red and blue electrical wire things and cleaned off any rust with some 000 steel wool. The fan turned freely by hand, but that's about all I can tell you about it.
I am very new at working on my car, and sometimes I don't know the correct words. Can anyone help a girl out? Thanks!

As you've gone to the trouble of removing the fan, check the brushes as these will often just need replacing. Also give the regulator a clean too.
