How to change a/c compressor on 1999ford diesel
You would need to have the AC system evacuated of refrigerant first. A local garage or AC shop can do this for you. Then unbolt the lines going to the compressor and then the bolts holding it to the brackets and remove from the truck. (watch it is heavy). Reinstall the new and hook up the lines. Drive back to the garage and have them perform a refrigerant leak test and install the proper amount of 134A refrigerant.
