As you probably know, it's located behind the dash. The dash has to be pulled back, and the evaporator has to be pulled out of the evap case. It's not an easy job. I will look it up tomorrow to get an idea on labor time. We don't do many of them on Wranglers so I'm not sure what it is offhand. I own an auto air conditioning repair shop / parts house. I can get you a good price on the core if you need it.
