Are Evaporator problems common on the Jeep Cherokee?
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
