2006 BRM w/ 370k. Driven in West Texas so A/C use pretty much continuous from March-October. Recently I've noticed the A/C performing getting weak at idle, the air from the vents becomes noticably warm and humid. The fans are running and the car does not overheat.
I evacuated and recharged the system with the proper charge of R-134a and get system pressures both before and after recharge of about 55 low / 250 high at 100* ambient.
If I increase engine speed to 2000rpm or above, the A/C cools down to the way it used to be.
The compressor is on its 3rd RCV with last replacement in 2015 at about 175k.
I don't want to throw another RCV at it if that's not the problem, as the symptoms don't match (no delay in A/C cooling at startup, etc).
Is it possible the compressor is just worn out, given mileage and use?
