Where is the orifice tube on a 95 Mercury Villager

I am posting this for a 1993 Mercury Villager WITH rear AC.

The orifice tube on a 1993 Mercury Villager WITH rear AC, is located under the van, on the driver's side, directly under the rear of the drivers seat.

Jack up the van on the Driver's side. Put jack stands under the car for safety.

Under the car, you will see multiple large AC hoses running from the front passenger side, to the rear drivers side on the bottom of the frame.

Two hoses go up into the car from underneath on the driver's side. They go into the van just about where the seat directly behind the driver would be located (they go into the rear AC control panel).

Both hoses have a snap ring connection that you can identify. The smaller hose (high pressure) will have another snap ring type connection about 6 inches from where it goes into the car from underneath. Unsnap that metal piece (the short one with two connections). You can now remove the metal piece which looks like a "J" about 7 inches long. There are two bolts that hold the hoses in place and a bracket, it is easier if you remove the two bolts to take some tension off the hose. This is all done from underneath the car.

The long part of the "J" will have a crimp about 4" down from the opening.

Look down into that side of the metal tube and you will see the orifice tab which is located about 2 inches into the tube. You will need a pair of long needle nose pliars to pull out the orifice. Be sure and clean the inside of the tube that holds the orifice, with AC cleaning solution before replacing the orifice. An indicator of a clogged orifice will be AC oil pouring out of the tube that goes into the car. a blocked orifice will stop oil from circulating back to the compressor and will destroy the compressor.

The parts listing shows ONE orifice, so that should be the only one. Apparently the cold gas must go through the rear AC evaporator before it goes through the front one, and then back to the compressor suction.

This ONLY applies to 1993 Mercury Villager WITH rear AC. If you do not have rear AC - this does not apply to your Villager.

Is it asking TOO MUCH that car companies add to the R134 capacity sticker on the inside of the engine ccompartment that also says "orifice tube location"and then tells you where it is located? This is not the first time I have looked for a day or more for the orifice tube and IT HAS ALWAYS BEEN A Ford.

This only applies to 1993 Mercury Villager with REAR AC.

The orifice tube is located under the car, on the driver's side, directly under the rear AC control panel. Looking under the car, you will see two AC hoses going up into the passenger compartment on the driver's side. The smaller hose will have another snap fitting about 6 inches down from where that hose snaps next to the other hose.

MAKE SURE THE SYSTEM HAS NO GAS IN IT.

Remove two bolts that help hold the two hoses to the frame ( in plain sight).

Using the snap fitting tool, unsnap the top of the smaller hose, turn the metal tube, then unsnap the next connection (a type of splice into the tube) and pull the entire metal tube out for easy access to the orifice tube. In the metal tube (about 7" long shaped like a "J". There is a crimp on the longest part. Look down into the hole on the side with the crimp, you will see the orifice tube. It is WAY down in there and hard to get to. You will need a special tool. Craftsman makes a special needle nose pliar ( part number 9 45661) that is really long and thin, and you can remove the tube with those instead of buying the expensive tool. They cost $9.00 and of course come with lifetime warranty.

The FRONT is controlled by an expansion valve block which you see behind the accumulator in the engine compartment in plain site with hoses going in and coming out.

The orifice valve is what gets clogged, the expansion valves are usually fine.

Hope that helps.
