Good advice, with a word or caution:

There is a possiblity that compressed air and a clogged drain tube can
result in "blowing off" the drain tube somewhere deep in the bowels of the
automobile where you may not want to, or may not be able to go. Also, some
of you may not have compressed air available to you. Try dribbling water
down the drains, one drain per corner, by pooring a little cup-full down
the gutter. Tilt the car if you have to to direct the water properly, like
for the back drains. If no water comes out, the exit varies with model but
should be on the exterior of the vehicle (!?), then try using a
non-invasive tool to roto-root the drain. It has been previously suggested
on this digest that weed-eater cord works well.
