comp may cycle when you have the defroster on
You should not put any oil in a Ford air conditioning compressor. The air conditioning compressor runs on Freon. The system should take about one pound of Freon.
If you have the heat on in the defrost position , the air conditioning compressor will cycle on and off to help dehumidify the air if the outside temperature is about 50 degrees Fahrenheit or warmer
If it's the compressor, the telltale signs are usually pretty obvious. It won't cycle, or you'll hear strange noises coming from the compressor, or it'll smoke.
Is this a noise you hear all the time or just when the heat/AC is turned on? If it just happens when your heat/AC is turned on it is probably the compressor kicking in and out. On my GMC van it was very quiet, but on my Ford Ranger it is loud clunk.
Which Compressor are you talking about ? The a/c compressor or the rear suspention Compressor ?
Where is the fuse for the a/c compressor on a 1998 ford mustang
Make sure your clutch is engaged on the compressor. you can usually do this with a metal paper clip in cycle switch, on the accumulator.
$1100 to $1300 if performed by a local repair shop.
The air conditioner dryer in your Ford Explorer, is located on the top of the air conditioner compressor. The dryer should be labeled.
You should have the system checked for the proper amount of freeon. The compressor will not properly engage if the system is low. Hope this helps.
If the belt's good, check the compressor clutch.
the fly wheel should have been turned.
