Yes, Jeep Cherokee, Grand Cherokees both have issues with the evaporators leaking refrigerant in many cases. Also problems with blend doors on dual zone systems and the actuators that move the doors are problematic. There is an informative aticle on this at DenLorsTools.com under Tech Articles. Well, I don't know if there is a problem, but I do know when I went into the local dealer to ask how much to replace on my 2000 Jeep Cherokee the service manager I was waiting for was on the phone answering that exact question for another Cherokee owner. I think that is more than a coincident. I think they have a problem. By the way the answer to my question - $1,100. I went shopping for a new car today... RKC

Labor times vary based on the location and experience of mechanical shops. Replacing the evaporator for a 2001 Jeep Cherokee Sport requires a tremendous amount of work such as removing the dash, draining the Freon, and pressurizing the A/C system. The average national time to replace an evaporator unit is between eight and ten work hours.
I think you mean the evaporator coil. It is the radiator like devise inside the dash that is part of the ac system.

I have had one evaporator replaced in my 1996 Grand Cherokee Limited and two replaced in my 1994 Grand Cherokee limited all were done by Jeep dealer and ran about 400 dollars parts and labor and took about 4 hours to complete. R-134A refrigerant is acidic this is why evaporators don't last.
