TSB or recall notice for 99 core issue
Anyone aware of any Technical Service Bulletin(TSB) or recall notice that involves Jeep Cherokee Heater Core or Evaporator core ?
Anyone else experience an issue with these parts ?
Thanks.

Well, they both go out after a while. Remember, the newest of these vehicles is almost 20 years old. There are plenty of threads around here about replacing them, but I don't remember ever hearing of any recall on them.

I believe BRM is right... however, I think that it's one of those parts that without proper maint. things will eventually hit the fan so to speak. And to me simply poor engineering as it's such a PITA to repair/replace once it does.
