Default Heater core bypass questions

hey family

my passenger rug is getting fairly wet. I believe it's water. My question is if i bypass my heater core can I still use my air conditioner for this hot summer? Am I jeopardizing anything by doing this?

Yes you can still use the AC. temp is controlled by blend door in the dash.

if you lift your carpets you will find rotted floors. water leaks in around the air intake on pass side. my 2000 needed 2 new floor liners/floor pans.you can buy them anywhere. lots of work.
your water has nothing to do with heater/air.

You will still be able to use AC. The two systems are not connected to one another.

The only thing you're doing that "could" be considered negative is that you're removing an outlet for your coolant to flow, so it has less surface area to cool down inside of and this means your radiator does extra work.

Bypassing your heater core temporarily will not harm your Jeep. You can do it for as long as you need to until you get your heater core replaced.

Water on the floor is common. Can be caused from leaky windshields, blower motor seals, and door seals among other things.

Good to know your heater core is not leaking.

that water leaks in around the air intake all year long. it will rust your floor.
