My air conditioning is not blowing cold air. Compressor and blowers work, and the clutch on the compressor engages properly. I suspect I'm just low on refrigerant, and want to check the sight glass to see if it's running clear, or has air bubbles indicating low refrigerant levels. The problem is, I can't find the damn thing. Can someone please tell me where the sight glass is and how to access it?

Thanks,

Chris

I don't recall there being a sight glass but I used a princess auto recharge kit (comes with pressure gauge) to refill my RRC AC a few years ago and it is still working great. The kit is quite easy to use.
