2003 Civic AC problem

Any help or suggestion on this are greatly appreciated.

My AC won't come on. The green dash AC light comes on when I press it. However, no cold air. Both the radiator and condensor fan do not come on. (The fans do work when the engine is running warm, both fans comes on to cool)

I did a search and followed the DTC retrieving process. No blanking lights.

Thanks!

Hmm... It sounds like the AC relay or switch if the radiator fans are not coming on when the AC button is pressed.

Do the vents have air coming out of them at all? If there's no air coming out at all it could be a fuse or your power transistor for the blower motor. Power transistor is piece #8 in the drawing below.
