Hi everyone,
My climate controls under the radio just suddenly went out today. (Went into a store and came out nothing) I turned the truck back on and nothing. Screen does not light up. But the rear climate controls work when you power them up. Absolutely zero issues before this. I checked all the fuses and relays associated with climate controls that i found in the manual. Is there any other things i could check or look for? I’ve owned the truck since 30k and has 108k now. Zero problems with anything except the usual: power running boards, power lift gate, ripping the door handles off in super cold weather after car washes, etc. any help would be great!

Climate control units are super common on these. You can buy on eBay or amazon. Sometimes they require a reflash or update to calibrate.
