i put a evaporator in this jeep. first one on these newer years. did many,many on the older ones.however, when this one was done. customer brought back with a complaint of a hissing noise. fan on low speed, usually on a/c but doesnt have to be.i verified complaint.it sounds like a vacuum leak on a system that is all electric....go figure.sounds like its coming from the heat side that doesnt get disassembled for evap. replacement. however, i completely tore down again to make sure it was nothing i did.it wasnt. the only thing i found was the door gaskets are coming apart just by touching them. so i fitted new seals on all the doors i could reach by not tearing box completely apart. also i forgot to mention.. air always comes out floor..little bit,but its there.i did a self diagnostic with no codes. all doors operate perfect. after reinstall same exact way. has anyone came across this issue?
thanks always guys
