I just got a 1996 Dodge Ram 3500 that has an A/C leak. I'm looking for a diagram that'll show the whole A/C system (hoses, etc) so I can try to figure out where the leak is coming from.

Thanks!

 

go to advance or similar parts store and pick up a bottle of flourecent yellow dye $10, which is specifically for the a/c system. empty the bottle into the system, turn the a/c on full blast. and you should see the leak pretty quickly

my guess is the low side schrader valve

 

unless its the evaporator core that's leaking.

Seriously, that is the only part you CAN'T see.
