[Mgs] clearing the drains in the heater system

[Max Heim]

There is a rubber tube with a squeeze bulb on the end at the bottom of the
air box. You can reach it from under the car.

I don't understand the purpose of the squeeze bulb -- it just fills up with
grunge that requires cleaning out. Why not just have an open tube? But there
it is.
