You know where the rear pressure switch is on a 2021 E450 short bus?

I have a 2015 Chevy express school bus that has perfect pressure when gauges are hooked up. 40 Deg in the front vents and 70 degrees in the rear a/c unit. Slowly gets warmer in the rear front stays perfect. Possibly expansion valve ?
