I did do the evap replacement myself. I don't know alot about MB or AC for that matter but I do know how to use a wrench and enjoy working on vehicles. Honestly I don't have a lot of money to throw into this car right now (who does?) and don't want to just start replacing parts that don't need replacing and don't want to keep paying $75 to have the mechanic do a diagnostic and have me fix the wrong parts. Prior to doing the evap core replacement I took the car down to my mechanic and had him evacuate the system. After completion I had him recharge it. He tested it for leaks and pressure at that time but did not give me the readings, I figure if something was wrong he would have said something at that time. I did not replace the AC drier. The car is also having electrical issues with the interior dash and console lights. See my other post... http://www.peachparts.com/shopforum/showthread.php?t=254065

Could this be related to the AC not functioning properly? This car seems to have alot of issues, my wife loves the car and just want's it fixed. Easier said than done!
