Trying to recharge A/C

Saxapealjz on Fri July 27, 2012 7:48 PM User is offline

Year: 1999
Make: Chevy
Model: Astor
Engine Size: 6
Refrigerant Type: r134a
Ambient Temp: 85
Pressure High: 10
Country of Origin: United States

A/C is not blowing cool air, so I bought a can of A/C Pro to charge it. The gauge would just fluctuate back and forth (all the way left then all the way right) every time the system (clutch) would cut on and off. I was told that the system needed to be emptied, so I totally bled the high pressure side. Next I turned the vehicle on and A/C to high, connected the can of A/C pro to the low side port. Now the system will not fill at all, and the clutch is not kicking in, which I assume is because the system is not taking on any freon. Please help with suggestions.

System needs to be properly evacuated before recharge for optimal performance and use only virgin 134a and never use any snake oil in a can because it can ruin everything.
Every time I go into a parts store for cans of 134a its always on the very bottom shelf, not many cans either, but always a boatload of blend refrigerants with stopleak above it.
Do not use any of them!

Evacuating the system something that I can do avoiding the high cost at the shop?

If you buy a vacuum pump, and if the system is at 0 psi. Not one of those pumps that run off an air compressor -- a real pump, that uses vacuum pump oil to seal. You don't need a professional multi-stage pump, a single stage will do.

But before you begin, I suggest you take the time to do some serious reading and understand why and how things are done properly.

You'll have to buy a recovery equipment at the minimum.

That gauge that jumps to max the min... is it a low side or high side gauge.
