87 GXL, Ready to resurrect the a/c, But need to know--

Does it use an expansion valve, or an orrifice? The Haynes Manual doesn't go that deep, and so far I've not been able to download the FSM info for heat/ a/c.

Also, before I just go a rippin' and tearin', if its an orrifice, where's it located?


Thanks for reading, Let me know!

 

OK, since I wrote the above, I was able to print the 67 pages of FSM that pertain to the heat and a/c systems.

So if you're into readin' and not writin', It has an expansion valve and its located in the "cooling unit", along with the evaporator.

So there. I let myself know.

 

expansion valves and orifice"tubes" do the same jobs on the system and they are located in the same places. Just follow the lowest line on the evaporator (inside) and if it has a bulge its an orifice or if it has a little vacuum activator looking thingie with a copper or wire in it, it is an expansion valve.
