Check your fluid First. Check your bleeder screw make sure it’s tight, should be located under the jeep drivers side bell housing area.
If fluid checks out ok.. I would replace your clutch master cylinder.. Costs about 80 bucks and takes an hour at worst even with bleeding the line. Buy a Haynes manual it will walk you through the steps.
If this does not fix your problem you’re screwed! Unless you know someone that can help you drop the transmission and get to your slave cylinder assuming it’s internal. (<-Worst idea ever Jeep) If you get this far you may as well replace your clutch and flywheel if they are worn..
Good luck and let us know if you have any questions! It's all pretty easy once you have done it a few times.
