Troubleshooting Hints - Lumbar Seats

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
^ To avoid misdiagnosis, inspect cable for binding which would prevent smooth operation or cause system failure.
^ Substitute I/P Circuit Breaker #1 with one of equal value (20 amp) known to be operational.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (refer to General Troubleshooting Procedures). Diagnostic Aids
