Re: Getting alot of heat from under the vehicle by the driver door.
The cooling fan is drawing air through the radiator and this air circulates around the engine and escapes at the underside of the engine compartment. Your jeep has the hydraulic cooling fan, which runs all the time, eventhough at 500 rpm when idling, but always moving air. Why you feel it more at the drivers side then the passengers side i don´t know. I do feel it on my jeep as well, is quite normal.
