HELP!!! 2009 Ranger Heat/AC issues

I have a 2009 ford ranger fx4 and when I turned on the ac today, it was blowing hot on every setting including max a/c. I'm pretty sure it's not the blend door or actuator. The ac isn't even kicking in. Would it be the switches? Any help would be appreciated. Thanks

Check it to see if it needs freon if it's to low on freon the compressor won't kick in.

I agree. mine kicks in on my 88 but the bearings in my compressor have gone south so it tries to kill the truck when it idles. try the freon, get a thing to recharge it at walmart for like 13$.
