I have a 2000 E350 15 passenger van that we have been trying to get a A/C evaporator coil for THE REAR A/C for over a month everyone keeps sending the wrong part(ford dealer, advance auto, Auto Zone, Amazon) any suggestions?

 

Because of the age, the dealer could have a problem, but they are your best bet.
You are new at this, you might ask one or two A/C shops where they would obtain the correct part. They do this stuff a lot more than some of the chain stores

 

it was at a shop they had the same issue. Does anyone know if this part changed in 2001

 

Dealership Parts Dept have the info of what part # is used in what years. You might inquire if they can provide the answer you seek.
