I have hooked SDS up and pressure does not change when compressor is supposed
to be off or on. I recall hooking up gauges and both sides stay the same but
may check that again. Either the valve in the compressor is not working as it
should or expansion valve is not. Or maybe it’s an electrical p
Pretty sure you can always tell if the compressor hub is spinning, vs not.
Pistons gotta pis, so if they're moving so is fluid. If it won't build pressure
either the one-way valves or shot, or the expansion valve is so open that
no pressure is built.
At its heart, AC is extremely simple, mechanic
Except this is one of those variable compressors that does not have a normal
clutch. So the hub is spinning all the time regardless of the AC being on or
not.

Didn't MBZ get rid of the clutch a while back, and newer ones spin all
the time?

Correct, which is this one.

So, we change from a simple, easily diagnosed system with its most
failure-prone part being an external, non-pressurized bolt-on to one
with all of that internal, difficult to diagnose, and expensive to replace.
Progress!
The wretched X5 has that system, and of course it failed and needed
a new (
Yes exactly. I don’t really understand why they had to make it more
complicated.

More fuel efficient I am sure. They can save .01% fuel by going to a
more expensive and complex system that will cost 8X as much in the long
run but you save $3.92 a year in fuel and the EPA and EUCommies are
happy you are not killing the planet as fast even though the life-cycle

True. Well the damn thing has not blown any cold air in 2 hours. I think
tomorrow I’m going to recover the refrigerant just to see if it’s leaked any
since I recharged it. Maybe it’s got a small leak or something.

Nobody EVER does system-level economics. "Does your dog bite?"

So with these compressors it could be the swash plate getting stuck, or
solenoid going bad.

So it appears. I’m guessing the plate either got stuck in the flat/neutral
position or the solenoid won’t move it out of that position.
