I've got to get my AC working again on my Cummins swapped 96 burb. I've used the stock components after the swap and while the AC wasn't great prior to the swap, its completely broken now. I used to have a 99 burb in which the AC actually worked pretty well, at least there was some air flow through the vents which is almost non-existent in the 96 model. Does anyone know if there are differences behind the dash with these models? (96 -> 99) I'm going to probably take a significant portion of the dash off to install a new evaporator and was wondering if there are other swappable parts that could make a worthwhile improvement to the interior comfort. This would be my ultimate boat towing rig if I could just get this done right.
