it hasn’t worked since I bought the truck but randomly it’ll pop on a couple lights

Nothing works on it though, no heat or cold air, no vent direction. Seeming like maybe I should just replace the whole unit at this point ??
 






Might be time for a junkyard pull to replace it but I'd first try to run the diagnostics. See attachment.

There may be a better writeup for diagnostics elsewhere, but this should tell you if there's any codes, if it's functional enough to do the diagnostic routine. There's also a wiring diagram attached and more wiring diagrams linked in my sig if you want to check the inputs to it.
