Dodge Repair: dodge 2500 air conditioner, side fender, dodge 2500

Question
PLEASE PLEASE PLEASE tell me where the orifice valve for the ac is located on a 1999 Dodge 2500 6 cyl turbo diesel 24 valve manual transmission before I die of heat exhaustion.  

Answer
It's located inside of a tube that runs along the right side fender.  It's serviced with the line only.  What you're looking for is a straight section and a couple of dimples.  The dimples hold the valve in place.  It's not serviceable seperate.  Sorry.

p.s. have you already replaced the compressor and suspect the debris from the compressor is clogging the orfice?
