Intermittently cold air will blow for a few minutes?

That would be a blending issue would it not? I watched the AC compressor while my wife turned it on. It will run a few seconds, then kick out for eight to ten seconds. The compressor clutch will cycle on and off like that until you turn the AC off.
There is one other issue I forgot to mention. This started about the time the AC started going out. Sometimes, especially with the fan set to high, it will just stop blowing. Several seconds later, it will come back on by itself and start blowing again. It will do that even with the AC off and just set to "blow air". Does not do it all the time though.
I hate to spend $40.00 on a can of gas just to have access to a gauge to check the gas level, but I will almost bet it is full of gas. I tend to believe it is an electrical problem. Maybe the relay for the AC? Maybe it is weak and will not hold a latch when energized, and will keep trying, but just cannot hold a latch "on". I will attempt to find the AC relay and test it. I will sure do that before buying a can of gas.
Thanks

I checked refrigerant its good actually all they way in red (but I figured its cuz it isn't working) and I have power going to compressor clutch the blower motor still works just blows hot fuses are good and I can spin the clutch on the front of the compressor by hand but it wont spin with ac on its an expensive fix and I don't have money to get it tested and then fixed going through a rough patch with money and I live in Texas so yeah its hot and ac was prologue used a lot before I got the truck it worked. Great then one day just stopped do you think you can help determine the problem. Thanks

No it doesn't engage with ac on I thought one time when trying to find the problem the compressor made a click noise but I'm not sure if it came from that or not it just sounded ike I did if that helps but the clutch never started spinning I'm not sure about the click noise like I said.I thought it might of came from the compressor

How would I go about doing that I don't think I have the resources to do so I have the diy gauge you know the one from a walmart or something

Ok can you give me steps of what should do and what kind of pressure should be in the hoses? And if they aren't what they aren't what they should be what would that mean I need or if they are at the right pressure what would be next step? I'm going to try and do it while at work tomorrow so I wont have Internet connection to follow up with you till after 5 I'm a golfcart mechanic so we have a lot of other tools and things where it is easy to work on my truck there

The psi is good on the lines and no the compressor doesn't kick on or cycle or anything

Yes I have power to the clutch and its manual climate control but the lights went out on it idk if that matters it all still works if I put to floor it goes to floor and defrost still does it just the illumination lights aren't working anymore. So you know I good places to get AC compressor clutch I also heard if the clutch goes out then there's probably not much life span on the compressor left and since I live in Texas I'm wondering if you think it would be better to get both or if it matters

Cool, thanks man I really appreciate it it has been I really hot ride and working in the heat. Blows when I can't get in a air conditioned truck

To have to buy a new drier and all the above when I buy a new compressor? And what about a salvage yard for the clutch or would you just suggest getting a new or rebuilt clutch from that site or Amazon I looked online its going for about 180 to 200 hundred just for the clutch
