5.4L AC stopped blowing
2004, 5.4L SuperCrew with less than 10K miles. (professional shop replaced engine).
Cruisin' home from work, the AC just stops blowing.
AND...the dashboard readout where all the AC controls/readouts goes blank.
Checked all fuses in the box under the passenger side kick panel. Nothing blown. Not sure how to check relays under the hood though.
Any ideas?

yes . check under the hood and make sure the wiring connector is set proper on the ac line . then check the fuses . I thinks it might be the body module. I hope im wrong but if your screen goes blank ....

when you say "wiring connector is set on the AC line", are you talking about the wiring harness than runs to the compressor?
And what is the body module?
Apologies in advance. Shadetree mechanic here.
I also misspoke about the fuses. I only checked the fuses that are refer to AC in the owners manual. I'm going to check all of them today.

its an hvac modual , provides a ground to your instrument cluster . But don't worry about the other harness , your cluster would still work if it were unplugged . but if you check under the hood like I said , look along the high side of the ac line , looks like a big nut with a plug on the end . its just an a/c high pressure switch . Other than that , id need to look at it .
