Answer
Rich,
If you have an air compressor (or you have really good lungs), you can get under the car and blow air up into the drain hose.  You should be able to find the little hose under the area where the glovebox would be.  Sometimes that will be enough to clear a blockage in the line.  Else, you will have to get into the heater box and clean it from there.  That's a lot more labor intensive.  If this problem keeps happening, it may be because debris or rust particles are plugging the drain from the inside.  Or possibly debris or insects are blocking the drain hose from the outside.
Good luck!
