If you jump the relay and the compressor runs on does it get cold? Sounds like low refrigerant or a bad low pressure switch.

I doubt it but I wouldn’t rule it out. Do you get 12v at the low pressure switch?

Not supposed to be 12v at the low pressure switch. Its a open/close switch to complete the ground circuit only.

As 85LTD and RS Logan mentioned above, check refrigerant levels and fuses. Might recheck your work at the cluster that you replaced. Something, somewhere may have come unplugged.

I take the truck to the mechanic and he check all the fuses,pressure relay ac panel and he can’t find it we replace the fuses box and still the same and then we try we the pcm and I don’t do anything, low pressure switch new, new relay, new ac control and we still don’t getting power to the relay box 🤦🏻🤦🏻 But soon he put poner into the relay box the ac start working
