98 tahoe no ac

[Natedawwg]

98 tahoe ac wont change from hot to cold. Its charged and when switching from hot to cold on the switch in the dash you can definatly feel its hotter on hot im not sure if that could be a sign that the actuator is bad

What are the high-side and low-side pressures?

Can you hear the actuators moving the air doors?
