1977 General Motors Diagnosis and Repair Manual

Used Factory Softcover Manual with minor shelf wear.

This Factory Manual contains a series of graphic diagnosis charts that will help you quickly troubleshoot and diagnose the problem the first time. GMDR charts are a totally new approach to systematic diagnosis and repair. repair.                                                                                                     

The charts are based on the fact that the vehicle worked correctly at one time and the problem is caused by time, wear, dirt or other causes.  Broken wires, poor connections, and corroded terminals are not covered.  The GMDR charts are intended to show you what to do, not how to do it.
