Welcome to AF! First step in the diagnosis of the rear struts is to pull the rear tires/wheels and look at the struts for signs of fluid leaking. The bladders should feel firm with the standard 15 psig residual pressure maintained by the compressor. If the bladders feel like a flat tire, you should check the operation of the compressor. If the compressor is running, but the bladders have a leak, of course they will not hold air. If you have a leak, this can be verified with a soapy water test. Mix a small amount of dishwashing detergent & water in a spray bottle and spray a mist on the bladders. (Same procedure used for finding air leaks in tires) If the compressor is not pumping, check the fuse in the main fuse panel identified as ALC. Of course, you could have leaks elsewhere, but first confirm that the compressor is operational.
