AC light blinking on Climate screen

[HiFiGuy]

My AC quit working the last time I drove my LC200. On the Climate screen, my AC "button" has a blinking yellow light, as opposed to the normal solid yellow. I Googled it and it seems it's either a relay, or RPM sensor on the compressor. I haven't found more specific info. Can anyone offer insight? I have attached pics of the fuse/relay box and inside of its cover, so hopefully it will help ID the needed part and its location. The left most gray relay on the bottom row (PTC/HTR 3) seems like a candidate?

Did the search mention anything about low refrigerant? I wonder if that’s a more likely cause?

Not that I ran across. It seems like they were leaning towards the relay, with the RPM sensor next.

Regardless, if it was mine. I’d first check for leaks and low refrigerant.

Yep, I hear that. I'll get it checked out at least to eliminate that as a possibility, if not actually fix the issue. The reason I didn't suspect that initially was that I was on a road trip, and it was working like a champ, then suddenly it wasn't.

I didn't think to come back until now to update this thread, but it turned out the compressor went out. So I bought a new Denso compressor, clutch, and a condenser. Figured if I was going to do it, might as well do it thoroughly, especially since I intended to keep it long term. It now works great. Since then, I have decided to sell it, so someone will have a nice new AC system, I guess!
