This is a common question in the Jeep Grand Cherokee site and searching the archives will provide you with a wealth of responses......all generally correct.
Basically, to get you headed in the right direction, the Jeep is constructed around a unibody frame and the drain hose from the AC condenser box runs directly into a frame member instead of protruding as a hose underneath the vehicle. Therefore there is no way to "blow out" the hose to clear an obstruction as you would in a vehicle with a traditonal frame.
To make matters worse the condenser box is lined on the inside with a styrofoam liner that is designed to prevent condensation from bullding up on the outside of the box and dripping onto passenger's feet in the front. This liner is fragile and is mostly responsible for clogs not only in the drain but also in the duct work. With a flashlight you can look into the air vents and maybe see peices of this liner in the vent.
The only correct fix for this is to dismantle the entire dash in order to remove the condenser box and clean it out. There are several short cut fixes mentioned in our archives that involve drilling a small hole in the bottom of the box but you do this at your own peril. By the way, removing the dash and then putting it back together is a long slow process and not hardly a driveway job. Expect to spend all weekend and probably more with no guarantee that you'll figure out the correct order of disassembly. AC shops will charge somewhere around $1200.00 - $1500.00 with almost every cent of this being in labor costs.
