I have an 01 expedition and the a/c worked great yesterday. Today nothing.it is coming out middle section and not coming out in front.I have checked every fuse that is related to a/c and all is well.there are a couple of relays under the hood that deal with this but I don't have a clue on how to confirm good or bad.the blower miter in front isn't working and I don't hear compresser kick in.I'm not sure if you hear compresser on these newer trucks.is there something else I should try or look at?thanks all
