Hi, the evaporator in muy X-type 2004 have leaks (the gas charge cant hold for more than 24 hours). I was adviced to change it, i know its in the passenger cabin, and i hace the JTIS, but the diagrams are not good, on how to dismount the dashboard, and the actual position of the evaporator, so any diagrams or pictures will be appreciated, i also would ask for advice, i have the chance to buy a used evaporator for $50, VS a new one for $125, or $50 for a "generic" new evaporator.

Any tips or advices on this issue would be really appreciated.
