Ranger a/c unit

[rum runner]

4.0L V-6 Automatic
R134-A refrigerant

I guess this is the time of year for a/c questions, and I have one

I am not sure which approach to take on repairing my a/c unit. Before the problem occurred, the a/c compressor ran in 4-5 second cycles but cooled ok and it operated that way for some time. I quit using the a/c because of the short cycles. Recently I turned on the a/c out of forgetfulness and it did not cool at all. The compressor still tries to operate in short cycles. Does this sound like a compressor on the way out or a need of freon?

Any help appreciated.

Typical low-refrigerant symptom.

Thanks guys............

This is what I learned in case it helps someone in the future.

Just add refrigerant only, no oil or other additive needed unless you changed the accumulator or you see lots of oil that has leaked out. First can of R-134a can be added upside down until compressor starts to engage and stays on. I actually layed 1st can on its side. After compressor engages hold can upright as not to damage the compressor. Put the R-134a can in warm water to speed up the process. Pressure gauge highly recommended.

Low side is on left side of engine on accumulator (small vertical tank) 1992 4.0 V-6

I'm thinking mine needs the same thing I have a '92 with a V-6 my problem may be (no leaks anywhere) low freon/refrigerant I'll be doing that before my trip to Florida next summer (taking the scenic route) won't need the A/C now it's getting colder here thank goodness the heater works ok. lol
