Evaporator issues
1999 S320 (88,590 miles) So I my EC light came on and the AC went out. Took It to Mercedes to and was told that I have a leak in the evaporator. I've added stop leak along with r134 a few times. It seems to last one to two weeks between charges. I was told to fix this it was going to cost me $3200!!! WTF! There has to be a cheaper way out or at least someone cheaper than Mercedes. Any suggestions are welcome. Thanks.
