Put a new compressor, drier, and expansion valve in least year and had a shop evac and fill. Worked all summer and now winter is over and I turned on my AC to only get hot air. I've check a few things below:

1. Checked fuses (not relays because I don't know how)
2. Checked pressure with AC on: Guage reads 0
3. Car on with AC off: Guage reads between 40-45 (if i turn AC off it will then drops to 0)
4. Car off AC pressure between 40-45
5. I hear a click, AC switch lights up green, and the fan in front of the condenser starts to spin

Thats about it. What next? I'm about to give up and drive warm, replace everything and hope it was a bad compressor (I have no clue....), or decide to fork over $$$$ to have honda take a look at it.

 

Figured it out. Just opened the valve when at 0 and it slowly filled to the correct pressure and AC works.
