2004 e500 sedan a/c problems
well a/c worked well since I had the car 75k miles on the clock now... ac blows hot air there was some point when it blew warm air for a lil then it kicked in and blew great cold air.... now I turn it on and the condenser fan motor under hood roars spinning really fast. inside cabin fan works. Put manifold gauges on the low side and reads 100psi when i turn ac on it goes down like only 5 to 10 psi like 95 or 90 psi what the heck could it be is something restricted or am I **** out of luck and need new compressor. Help greatly appreciated thank you

I really didn't want to start messing with the refrigerant but if needed be ill recover vaccum and weigh in the charge(have all equipment i do hvac) but seems weird that it is cooling very well and the problem seem intermittent its like when this car knows i need some a/c it say nope... thats why I was leaning toward a sensor/wiring or compressor... but thanks ill further investigate
