Hi, I'm having issues with the air seat in a 744K 1DW744KXAEC659543, it takes awhile to pump the air bag up and goes down after an hour of use. I've replaced the compressor as it was making a horrible noise, no air leaks that I can see or hear, both gas struts were replaced as they were leaking but the seat still doesn't perform on the air side. Its a pretty simple circuit so not sure what I've missed TIA
We have a lot where the hose gets pinched in the scissor mech. Of the seat. Boy what fun a little piece of hose can to replace. Switch vents to atmosphere.. Soapy water in a spray bottle and flashlight and 4 different kinds of pliers to get all those push pins out and give it a squirt down
