These mini-techs are being taken from GM's Chevrolet Service News. The Service News publication was provided by GM each month to its service departments. Each month this publication covered persistent problems that service departments might be facing, and provided information on how to fix the problem.
These Chevrolet Service News publications by no means covered all the problems a service department faced with the introduction of each new years models. Likewise our seven mini-techs will by no means answer all the problems.
Your best source for information on repairs and restoration are the Shop Manuals and Assembly Manuals for your year Chevy without these publications you will be working in the dark!

All of the drain hole locations in the body are shown in Diagram 3.
Each door is designed with two drain holes (A) which are located along the door bottom. Their purpose is to drain off water which enters the door inner construction. Each hole is covered by a sealing strip which prevents dust entry into the body The shaded surface of the sealing strip should be lubricated periodically to prevent the strip from sticking to the metal.
