AC Light Blinking. Clutch not Spinning

[armcomdes]

2007 ES350

Used ACPro for years. Always worked.
AC light is blinking. I replaced AC relay with no luck
Charged the refrigerant again, but Clutch not engaging. Little window near Out port shows no liquid.
Vents blow regular air.
Is it time for the dealer? Or am I missing something?

Thanks. I have watched that video -- very comprehensive. I was looking for some simpler culprits like Low refrigerant/Relays/Fuses. Maybe something I overlooked. I'll check the cabin filter.

Is there a way to pin point a sensor issue before dismantling the dash? 

When trying to top off the refrigerant, you have to set the system to high so it comes on and opens the flow. This isn't happening. Is this a sensor or relay that can be checked and replaced, or is it more complicated than this.

 

Thanks in advance.
