How do you repair the air conditioner on a 2000 ram van?
You would need to be more specific with your question. You are not providing enough information to supply a meaningful answer.
It is not in the factory repair manual. They refer to the diagram in front of the radiator on a 2000 Dodge Ram 1500. It is a very basic diagram and leaves a lot to be desired. I am looking for a diagram myself as a pack rat chewed off both ends of one vacumn hose and I cannot find where it attaches on the firewall.
