My 2002 gmc sierra a/c blows cool not cold. Compressor cycles but seems to do so too fast. Evaporater cold but on other side of orfice tube is ambient temp. I have replced orfice tube. Freon is full.


Sounds like expansion valve(orifice tube) was installed backwards, it is directional. When Freon is full, suction line(Low Side) should sweat all the way back to the compressor. Also a new dryer would not hurt.

What model ac. compressor will enter change with a 95 gmc Sonoma sle 4wd


Salvage yards have interchange manuals (very pricey), but why would you consider putting an old used ac compressor on? You will need to replace dryer and orifice tube anyway, so why not do it right?

The low pressure on the air conditioner is reading to high


Several things will cause this, but most often it is a tiny bit of moisture trapped in the system.
Have the system completely evacuated with a deep vacuum. Then recharge it to mfrs. capacity.

Ac cycles on 92 blazer ,new compressor,low switch bad?


Did you replace the dryer,and the orifice tube?If the orifice tube was not replaced,this is most likely the problem,what are the pressures while it is running,and how much freon is in the system?If the system does not have enough freon it it,it will do this,but if it does,the cycling ac compressor is because of the orifice tube,if the system was not flushed out,and there was a new orifice tube installed ,then it is stopped up again.Let me know something so I can help.

Blew high pressure switch off compressor replaced that. wont take but 1 can freon high pressure


If you have not put too much oil and refrigerant in the system, then you have a restriction in front of the compressor. Most likely a plugged orifice tube, but possibly the receiver/dryer/accumulator. Both will have to be replaced and the system flushed. The orifice tube requires special tools and skills and unfortunately, it would probably be better to take this job to a professional at this point.
