Orifice Location? - 95 Explorer..
Can someone tell me exactly where the AC orifice for a 95 Explorer is located, and how hard is it to get to? I'm putting a new compressor and accumulator on and I know I need to do the orifice as well. None of my manuals indicate where it is located. Thanks for any and all help.

If the old compressor failed internally and contaminated the system, you should seriously consider replacing the condenser also. The design of the condenser tends to trap debris that will come loose later and plug the orifice. This, in turn, will damage the new compressor. Flushing usually won't get all of the debris either.

There is a rubber/metal line running from the bottom front of the evaporator box to the bottom connection on the condenser the orifice tube is installed in this line it is called the "Liquid Line" by the parts guys it is in the front portion of the tube which is connected to the condenser.
Bad news is that it requires a orifice tube extractor to get it out which will set you back about $60 bucks. To cheat just buy the orifice tube and never install it they are about $5 bucks but to validate the warranty they always want to see it and the accumulator on the same invoice as the compressor.
Best way to do the job buy a brand new liquid line which should set you back about $20-25 and get a Variable Orifice Valve or SmartVOV also about $20-$25 which changes its orifice diameter in response to system pressure this will buy you a couple of MPG at low speed and better cooling as well. I have these in both my exploders.
You dont need the remover to put the orifice tube in just to take it out.

From my experience, those VOVs have a high failure rate. They're also uneeded in a system designed for R134a. They were designed to help with idle and low speed cooling in retrofitted R12 systems.
As far as "cheating" and not replacing the orifice..........way bad advice, dude. Trying to save $25 and taking a chance on grenading a compressor isn't very smart.

I did not say it was good advice that's why I called it cheating, but if you do not have the tools you can do more damage to the system by trying to remove it improperly. Point here is you need the right tools if you do not have them leave the system to a professional.
And if you are in a hot climate A/C may indeed be a life or death issue compressors are cheap compared to ER visits.
Also the SmartVOV is now standard equipment in Police and Taxi fleet packages - It is true that it has a higher failure rate but it has moving parts as opposed to a simple brass tube so of course it will fail more often.
But they fail due to dirt in the system a proper flush with proper solvents eliminates this problem.
