Have 1994 E350 club wagon the ac is not working , the front is working but the back unit is not, is the back a whole separate unit with no relationship to the front.
Well you've got only one compressor...so this has to be a diverter/control to the back section~
the back is a whole other section- connected by long hoses that run through the side panel- check to see if the back fan is coming on-
Thanks guys that helped immensely
