My mechanic has advised that I replace my a/c evaporator. The system isn't cooling and you can smell a foul odor in the car with the freon leaking from the evaporator. I replaced the compressor, drier and other components two summers ago. I've been putting off replacing the evaporator because I'm worried that removing the dash will cause other problems (rattles, misalignments of somesort, other "minor" annoyances). But with all of the freon now out of the system and the Middle Georgia heat taking its toll on me, I'm thinking I should go ahead and do it. Anyone done this? Good or bad results?

I can barely remember a time when my A/C blew cold so perhaps it will be worth it! It's a 1985 300D Turbo with 265K. Other than A/C and a few minor things here and there, runs like a dream and is in tip-top shape. She's my daily driver and I want to keep her in near-perfect condition.
