So my a/c went out on my 08 overland. added refrigerant and hear a leak coming from the lines going to the rear evaporator core. in order to replaced the lines u have to replace all 4 lines that come in one piece (coolant and a/c) and that part is on back order or discontinued cant find it anywhere. so i was searching the old interweb and found these generic block off caps that cap off the lines going to the rear evaporator. has anyone done this before ? did it work ? will the generic size cap/ plugs work ?
