How can you fix your ac compressor on your 1991 Ford Taurus SHO?

Answer 1

AC compressors are relatively easy to replace, typically it's only the serpentine belt and a few bolts. The hoses are a little more trouble. Typically a worn or failed compressor has deposited debris in the refrigerant lines requiring that they be replaced or cleaned. The procedure is: 1, extract any remaining refrigerant from the system into an approved container suitable for recycling. 2, remove the serpentine belt, disconnect the refrigerant lines from the compressor then remove the bolts and lift out the compressor. 3, Examine the inside of the refrigerant lines, looking for any discoloration. If the remaining oil is not clear, you should flush all of the refrigerant lines to make sure they are completely clean. Since you'll be replacing the old R12 refrigerant with 134A, you should probably do that anyway. 4, Since the vehicle is "experienced", it would probably be a good idea to replace any of the rubber refrigerant lines. That way you can avoid some problems. Since they are that old they'll be leaking soon anyway so you're not really wasting money. 5, Replace the receiver/dryer. 6, connect the new compressor and refrigerant hoses. 7, Connect the serpentine belt. 8, evacuate the system. If you don't have an evacuation pump for air conditioners, have someone do that part for you. You need to verify that there are no leaks anywhere in the system BEFORE you put the oil charge or the refrigerant. Air conditioning compressors are not repairable by the home mechanic. Unfortunately your only option is to replace it.
