Look around and see if anything that looks like the images in the attached are near were the lines enter the firewall (Evaporator Area).https://www.google.com/#q=picture+of+auto+expansion+valve.
A lot of the late model cars and trucks do not have independent expansion valves, they are built into the receiver drier.
GM and some other manufactures have switched to a Orifice Tube. The Orifice tube is inside the high pressure line where it connects to the evaporator. Orifice Tubes and Expansion valves... auto A/C diagnosis, repair & troubleshooting help. A good description and image is available in the web link.
Auto parts houses sell Orifice Tube Removal tools. A pair of needle nose pliers can also be used. Be careful if you are trying to remove a Orifice Tube. They like to break off easily.

The AC on my B3350 stopped cooling - almost. It did cool the air measured at the outlet by about 12 degrees.
I had cleaned the condenser, so I didn't think that was the problem. I was wrong. The condenser was mostly blocked with a fine gray "flock" from the field I was mowing. It looked just like the aluminum fins. After cleaning the condenser all returned to normal.
I made two cleaning wands after that experience. One is a long reach blow gun from Harbor Freight. Cut the bent tip off, cut a thin slot with hacksaw near the end of the tube and plug the tube end. Made a second one for the water hose. Have only used the air gun so far, but it works really well.
