95 Bonnie air conditioning troubleshooting

[DonnieBonnie]

That's shows freon okay,. but very little cool air. Any hints on what to start troubleshooting ?

How do you know the freon is okay, and is it blowing plenty of air, just not cold, or is it cold air, but just not a lot of it?

I added refrigerant to the appropriate pressure reading, but not getting cool air

[RJolly87]

Is the compressor running at all? If so, is it staying steadily engaged or cycling? Was it running when you started adding refrigerant?

I don't know if this fits your issue but my 92 SSE had a lot of "air" leaking from the AC ductwork seams before the dash vents. Sealing those or fixing the deteriorated foam seals increased the airflow out of the vents.

Try this , viewtopic.php?f=45&t=2432 , i was same problem.
I clean this with hipressure air and vacuum cleaner , look this after one year ,

When you say you checked pressure, did you use a gauge set, or a gauge on a can of refrigerant? Knowing the high side and low side readings will help identify the problem. A properly running system will keep the compressor engaged most of the time on MAX cool, but when you change to regular A/C , it will cycle. Fast cycling ( on/off/on ) within a few seconds usually indicates a low charge.

Other things that can affect cold output are moisture in the system ( how did you charge this back up? Was it completely empty? ) Also, heat transfer. Is the evaporator and condenser clean of debris? Run cold water on the condenser and see if the temps go down significantly. If you have a bad orifice tube, that can cause problems as well. A weak compressor or a blend door that isn't keeping hot coolant from mixing with it can also cause problems.

Good luck and report back what you discover.

Also just to note R134a is a fickle beast... If its a tad low it wont function properly, if its a tad over charged it won't function properly.. Its not as forgiving as R12..

Is the compressor and its related parts all original?
