What is your question?
I am working on a Chevy Venture with intermittent coolant gauge. Complaint was no coolant gauge operation, and cooling fans were not kicking on. I unplugged the ECT connector to verify if the fans were bad. They ran perfectly fine. However, as soon as the ECT is plugged in again, they shut off. I replaced ECT with a known good sensor to test if the sensor was bad. It still did the same thing. So is it the connector/wires, ECM, or my luck?
