Installing A/C on a ranger

I have a 1994 Ford ranger without A/C. I want to put A/C on this truck and was wondering what type of an undertaking it is. Is the wiring already in my harness from the factory or do I have to modify that. Just looking for someone who has done this before and can help. Thank you very much
 
I did most of this swap but never finished it on my 93. You will have to look at the schematic to see if your truck is wired for it or not. Mine was. You can look in the power distribution box to see if the wires go to where the a/c relay is supposed to go.

Other than that you will need the evap coil/a/c box, accumulator, suction and discharge hoses, condenser, a/c ready hvac control, compressor, and a/c wiring harness. I believe the harness plugs into the large square gray connector under your steering shaft and goes across the top of the engine. It should just plug in from that point. I got most of my stuff off an explorer. It would be expensive to buy each part separately, but if you can find a donor that is the way to go.
 
I just finished the swap on my '97. My truck is a fleet truck so my truck was missing the wiring for everything in the cab but was wired for it under the hood. The way to tell if it is wired under the hood is to look for a round plug near the wiper fluid reservoir with 2 wires going into the plug. If it is there, it's mostly wired for it. My friend totaled his nearly identical truck so I was able to buy the entire system from him for about $120. He had an xlt so I had to take out the dashes of both trucks and swap dash harnesses. He also had two airbags and I had one so I had to cut the passenger airbag wiring and solder the wires for the airbag plug together, and take apart the airbag off switch that mounts next to the ash tray in dash, plug it in, and stuff it inside my dash because I have a power port in that location. That's it for the interior.

In the engine compartment, you need to take out the black box in both trucks on the passenger side by the firewall that houses the blower motor and swap them. WARNING! BEFORE YOU REMOVE ANY A/C PARTS BE SURE THE SYSTEM IS FULLY DISCHARGED! I made that mistake and painted the ceiling green with Freon. It burns the eyes also. I thought a pipe was broken during the accident and it discharged then. I was wrong. You also need the condenser core that mounts in front of the radiator, the compressor and associated plumbing and possibly the mounting bracket if it is not already on your block. You also need to pull out the wiring harness in both trucks that runs from the fuse box area and ends at the alternator. After that put everything in your truck and hook everything up. You also need to change the serpentine belt obviously because you have an extra pulley now.

It took me about a week to get everything out of my friend's truck, but it was smashed up pretty bad. I changed the interior wiring in about 5 hours, and another 4 for installing everything under the hood. It is doable, just have to do your research before hand. Cheers. :icon_cheers:
 
Nice! Sounds like a complete pita, but the extra parts truck woulda lit a fire under me to do it as well
