I live in S Cali and have a 2019 Expedition. A/C blows very cold. Temps here have been 100+. You might check to see if yours had a hose missing for the A/C drain along the firewall. Some were missed in production assembly in 2019. If your not cooling properly you have other issues going on. The only way to tell is gauges to test freon level. If it is very low on freon you may have leak in the system. That takes many steps to confirm that. Good luck. Many scenarios that could be the cause of your problem.
Interesting as I did some common sense detective work and ours works better if the rear is on. If the front is on by itself, it blows cool air not cold, as soon as we put the rear on both blow colder good but not great. Weird.I'm following this thread because mine is going in next week for Rear AC blowing warm. Front blows cold.
But I did recently replaced the Y fittings, this weas 4K miles ago. I think mine might be the rear evaporator, but it is a slight coincidence.
