Car is outside running as I write.

Started project with engine stopped. Ambient temp on porch is 85F, car dash says 90F.

Backed off the penetrating thing in the can connector, attached can tightly. Then connected hose to fitting on dryer. Lots of pressure in there, had to push on real hard.

Turned can penetrator in as far as it would go, started car. Set a/c on lowest temt, fan on high. Went to look at gauge.

After 30 mins of this, here is what I see:

Uninsulated line down on chassis rail is quite cold to the touch.

Air center vent is 85F.

Compressor is cycling on and off in 5-second intervals.

Gauge drops to 22psi, compressor kicks in, rises to 45psi, compressor kicks out.

Can feels about as heavy as does an unused can.

So - is no R134a going in?

It is leaking out as quick as it goes in?

Since the uninsulated line is way cold, something is working, the variable orifice?

Is there some control in the fancy-schmantsy ACC climate control that is bad?

What can I do next?


All ideas are welcome.

Thanks to all.

Bob
