Tyler,

This is a common occurence in the GP. Easiest way to find the drain tube is to stand against the passenger side fender. Locate the power steering pump (back of motor) and straight back from there, on the firewall, look for a 1/2" dia. tube with a 90 degree bend pointing toward the ground. Of course if you've got water, the 90 degree tube might be missing and part of your problem. :rolleyes:
Use a coat hanger or some other type of device to unclog the tube once you find it.
You may also want to locate your blower motor (passenger side floor under the felt cover) and pull the little rubber elbow going into the motor housing. water tends to accumulate there also.

Hope this helps!
