2008 with AC issues - Trying to diagnose exact issue

I have a 2008 Prius with 270K miles which has proven extremely reliable over the years. Unfortunately, the AC has been blowing warm air since last december. With summer fast approaching, I am trying to hopefully fix it without too much $$$.

The blower works fine as it has a new motor. The heater works as well. When in AC mode, aside from not cooling, I see that the condenser fan is not coming on. Related fuses in dash and fusible links in the engine compartment are good. I replaced the AC amplifier, since it was cheap ($10 on eBay) to no avail.

The sight glass shows oil inside. No bubbles. The condenser appears visually ok. I tried to retrieve the codes by pressing the AC and circulation buttons on the steering wheel, but unfortunately the spiral mechanism is damaged, so they do not work.

Any recommendations on getting an android based app and OBDII adapter to read the codes? I am hoping it's a leak and not the compressor that is damaged.

Thanks in advance!

 

Thanks Sam. Good advice. I'll have the system checked at a shop. It may not be practical to replace the compressor given the age and high mileage of the car...

 

Thanks for your reply smokeGTI. I don't hear anything coming on in the engine bay when the AC is turned on. I also have a 2015 Gen 3 and the condenser fan in the radiator area immediately comes on when the AC button is pressed.

And yes, I am hoping it's low on refrigerant. This why I was asking for some sort of software to scan for codes before I take it in to a shop. Dr. Prius perhaps? Techstream?

I don't think it's the inverter coolant pump. There would be other issues with the car, it runs fine otherwise.
