Help-Front ac wont come on.

I have a 03 Eddie Bauer Excursion w a 6.0L. On the way to work this morning the ac was cool and worked fine. It was running when I turned off the truck. I got off work this afternoon and turned on the truck, no AC. The whole unit is off, like its not getting power. No lights, no indicators, and no blowing air. Too hot for this right now. Rear works fine.
So far I have checked fuse 23 which the book says is power to climate control. The fuse is fine.
I guess I am hoping for a little help or a direction to look before I give up and take it in.

Someone sugeested turning the headlights on and off a couple times with the truck running. It worked. That has got to be both the simplest fix I have ever heard of and one that makes no sense whatsoever.

Well I'm not an expert but I see you don't have many responses, since there is nothing working on there possible it could be the switch or your blower motor went out, couldn't hurt to test the resistance of your blower motor? I don't know the specs but that's all I could assume, either switch or blower motor. Hope I could point you in a general direction

Also don't just go off one specific fuse from the book, check ALL the fuses in the panel, pull each one out and examine thoroughly, I've had a couple occasions a fuse was out that I overlooked because it was for something completely different.

I did.

The turn on and off the headlights with the truck running did. But it makes no sense to me really why it did.

Sounds like a bad switch or wiring issue. Good luck. I hate wiring issues.

its not the switch. Apparently its a known issue w the 6.0l trucks and electronic climate control. Supposedly it does something with voltage to the unit. I saw it when i searched and forgot the Ex had the electronic version my old f250 didnt.
