how to change condenser on renault trafic van?

If you mean the Air-con condenser, Not very difficult to change, But once changed, you need specialist equipment to first vacuum the system test the system and finally regas the system, as well as needing the refrigerant gas. Also the longer it is left after changing until vacuum, the more the moisture in the system is going to corrode every thing from inside out.
