2003 ford expedition. Why would my ac not be working?

What is your question?

The ac is not working. Everything is good the compressor, fuses, and button inside. It is just not working. We have checked all of the power with a light. We have checked fuses. The pump works but won't kick on when we hit the ac button. We are lost....

How long has your 2003 Ford Expedition had this problem?

It worked 2 days ago
