Does anyone know the correct part no.for the evaporator for my 89 W250.
I live in Canada and am being told that they are no longer available from NAPA here.
I live in a border town with Michigan so have no problem ordering in the USA if need be. Just want to know where it is available and manufacturer and part no.
Currently it is not leaking but I must change the heater core. While I'm there it could probably use an evaporator replacement as it could begin to leak anytime as it is now 25 years old and still original.
Any help would be appreciated. Thanks in advance.

 

I have heard good and bad about these aftermarket replacement units. You can use a Evap core from pretty much any dodge ram from 80-93...they are all the same basic Heater/A/C box.

You can go to rockauto.com and find the part you need there.
