Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Humidity Method
If humidity or moisture is suspected of causing intermittent failure, lightly spray water on the front of warm radiator to increase humidity in the engine compartment. Check for malfunction by monitoring suspected circuit or component with a DVOM.
If vehicle has interior water leakage, the water may have damaged the Electronic Control Module (ECM) or corroded the electrical connections. Carefully inspect ECM terminals and electrical connections for corrosion.
