I have a 1991 300E. I just had the compressor replaced by MB. After three months of perfect performance, my CC is now acting pretty weird. Now and then I hear rapid clicking under the dash on the passenger side, then it stops after 5 seconds. I then notice that the CC fan (on high speed) runs for a bit, shuts off for five seconds, then comes back on slowly. The a/c is also not as cold as it should be, and it was cold!!

Would this relate to the fuse box in any way?

HELP!
