Intermittent Simulation

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 1994 GMC Vandura Special, 1994 GMC Vandura, 1994 GMC Rally Camper Special, 1994 GMC Rally, and 1994 GMC Forward Control. However, it is still accessible from the selected car via links, so may be relevant.

Use following methods to reproduce conditions causing intermittent.

Apply light vibration to components.
Heat component.
Wiggle or bend wiring harness.
Spray component with water.
Remove/apply vacuum supply source.

Monitor circuit/component voltage or resistance while attempting to simulate intermittent. If vehicle is running, monitor for self-diagnostic codes. Use test results to identify faulty component or circuit.
