Question about 1998 Jeep Grand Cherokee
It probably is blocked and i think the easiest way to unblock it is to drill a hole in the bottom of the heater box.You can pick up a plug at the dealer to block the hole you drilled. The drain tube is located inside the frame so it cant be blown out thats why you have to drill the hole. Call the dealer and he will tell you what size hole to drill
