Message	Turned on the air conditioning the other day, the fan blows just fine and the controls all work like they’re supposed to, but the AC clutch will not engage and turn on, so basically you’re only getting outside air from the fan blowing. I hooked up a pressure gauge to the low pressure line on the HVAC system, and it reads in the red saying it’s overcharged. Any idea what to check as to why the compressor will not engage? Thank you!!
