Unless you can verify what the pressures are you will need to have a shop check it for you. Low pressure will give the symptoms you stated. Also if you did not vacuum all the air out before you added the stuff then a shop will have to perform a a vac and recharge. Plan on paying the piper if you did not do this yet. You can only accurately charge a system after a vacuum has been put on the system and then held there for a time to see if the vacuum stays.

It sounds like you've done just about everything except to check if there is a bad or intermittent wire causing this or perhaps your low-pressure safety cutout switch is possible going bad causing the compressor to kick on and off?

Freon for 1990 oldsmobile 98

This car uses R12, it is no longer available, you must convert it to R134, this requires the compressor and reciever dryer be replaced and the system flushed out and the new PAG R134 refrigerant oil be added and new charging port kits installed. Is that car worth this effort?

Replacing compressor, accumulator and orifice tube on 97 k1500. how much pag oil goes in compressor, and how much goes in accumulator. book says to empty oil out of old accumulato, measure and replace that...

Look for a light blue label in the engine compartment, the refrigerant capacity and oil capacity are on that label. But, being a '97, that label might be long gone. That information can also be found in a service manual. Manuals can be purchased at parts stores and you might even find one at a library. You could also call a dealer's service department and ask them.

Replaced the compressor in my 1999 Dodge Caravan. The pulley failed on the old one so I bought a new compressor with clutch. I recovered the R-134a and replaced the compressor. I recovered 1 oz of old from...

the new compressor was likely shipped pre oiled. it should have had a tag on it saying if it was oiled or not, and how much. if you added more oil, the system has probably been over oiled and hydro locked. recover the refrigerant again, if you are working with an actual automotive a c machine you should be able to draw that extra oz of PAG oil out, then recharge refrigerant. hopefully that will do it! otherwise, you could have a restriction in your system, possible from debris in one of the compressors, in which case you will need to flush the lines out. good luck!

I tried to charge the air conditioner on 95 suburban. it doesn't act like it wants to charge. the compressor keeps cycling on and off so can't get a good read on the pressure.

The system could be low on oil. The compressor will shut itself down if it detects a lack of oil or refrigerant. Try adding compressor oil (comes in a can similar to the R-134A) to see if the compressor will stay engaged long enough to accept a charge. It's also possible that the system has so much air in it that it needs to be evacuated before refrigerant can be added. I'd try to add the oil and see if you have better sucess adding refrigerant REMINDER: Have AC on HIGH when adding refrigerant with car running

Hope this helps with your AC problem. Please post back with any other questions. Best of luck.

1998 Blazer A/C blows hot air...the heater works's full of freon cause it wouldn't take anymore...what can the problem be?

This could be the problem "it's full of freon cause it wouldn't take anymore"
A/Cs are not filled until they can't any more.

Here is what you should have in it.
The refrigerant used should be R-134a
The total amount should be 32oz
The type of oil in the A/C should be Pag-150
The amount of Pag-150 should be 8oz

More than 32oz of R134a is overcharged.

You should also check to make sure the compressor is engaging.
If not,It could be Overcharge,bad compressor,Bad pressure switch,or a few other things.

I hope this has given you ample info.

Please take time to rate this fixya.
