I pulled the HVAC box out of the car and replaced the evaporator...fun! My question is on the evap sensor and here is a link for a picture of it so we are on the same page http://catalog.eautopartscatalog.com/mercedesshop/sophio/wizard.jsp?partner=mercedesshop&clientid=catalog.mercedesshop&baseurl=http://catalog.peachparts.com/&cookieid=1YC1BU6YY21D1D7CJ3&year=1981&make=MB&model=240-D-002&category=R&part=A%2FC+Evap+Temp+Sensor

My question... does the very end of the copper solid core line need to be touching the evaporator or just the air space close to the evap?

thanks ahead of time!
