If pulling the relay with it blinking does NOT stop the blinking, then the blinking is caused by something in the instrument cluster. That means forget fooling with the coolant level sensor or sensor wiring and focus on where the problem really is, up front. It may need the capacitor replaced inside the temp gauge or a replacement of the temp gauge. It could be a wiring path weakness near there too, in the cluster or the cluster ground wire. If pulling the relay with it blinking DOES stop the blinking, then the blinking is caused by something in the coolant level sensor system. Usually that means at the sensor itself, like a bad sensor, sensor probes coated with something that should be cleaned off, or bad contacts at the sensor wiring connector. It could be the sensor wire junction at the round 7 pin inside the engine compartment wiring box, it could be the 43/42 relay itself. The coolant level early warning system can save your engine from cooking to death after a simple leak that could be easily fixed. It should be kept in working condition.
