Hi Scotty,
I have a 2012 Range Rover Sport that the AC is not working, I bought the truck this way ad the old owner stated he replaced a hose and its empty, not true, there is Freon in the system. I put gages on and the low side reads 110 and the high side is zero or hardly any pressure. I am hoping you can point me in the right direction.
Assuming your gauges are hooked up and working properly those pressures are way off. You didn't say if your readings are static pressure with the system not running, if so you have a blockage preventing refrigerant from entering the high side. (Static pressure should be the same on both high and low sides of the AC system.) That suggests that possibly the compressor has failed and contaminated the system with metal shards which have plugged things up. Can you turn the compressor by hand, smoothly and without any bad noises? (You need to turn the clutch plate that the crank is connected to, not the pulley.)
Generally speaking, ac systems are far beyond the range of the DIY repair. A professional, automotive ac specialist is worth the price.
I will check
If the compressor is seized up or making grinding noises pretty much every component in the AC system needs to be replaced due to contamination. What you want to do is turn the clutch plate. It is not necessary to remove the belt. What you want to do is turn the part labelled "front plate" in the illustration below, in normal direction of rotation. It should turn smoothly and easily by hand.
