2009 Corolla 1.8L Forums indicate the AC relay will be in the engine fuse box, but it is not there (HTR 50A, M/G CLT).
Where should I look? Thanks

Welcome to 2CarPros. It should be in the relay block on the passenger side under the hood or in the junction box on the left side of the dash. It depends on which AC system you have and which plant the car was built in.

Okay, time to hook a gauge set up and see if there is any charge in it. Low/no pressure will prevent the compressor from engaging.

If the charge is low or gone, the first thing would be to determine why, you don't want to fill the thing and have it all leak out in a week. I would recover the charge in the system if there is any. Pull a good vacuum and see if it holds with no drop. Any drop = leak. Take a look at this guide:
