Has anybody had any problems with their JK heating system, passenger side Is Luke warm and the driver side comes out cold, any opinions from anybody what might be happening?

Have you checked your hoses to the heater core in the engine bay, should been very hot to the touch (can use a heat gun). If your core is not blocked. On my JK the blend doors are manual and they stick after 13yrs. Sometimes I pull the glove box and reach in to get things moving.

Yup, this is either heater core or blend door related.
