Megane Windshield Washer Heater Fault

My 2022 Renault Megane hybrid's windshield washer heater is acting up. I'm getting an error, and the spray nozzles freeze when it's cold. I've got nearly 50000 km on it, so it's probably not wear. Fluid level is fine, and nozzles aren't blocked. I suspect a bad cable or plug to the heater. Anyone seen this?

That's frustrating! I haven't seen that on a Megane, but heater issues are annoying. A faulty connection is likely. Have you checked the voltage at the heater connector when the washer is on? If no voltage, tracing the wiring might show a break. Is your washer fluid rated for the temperatures you're seeing?

Good idea about the voltage! I haven't had time to test it yet. Where's the heater connector located? And yes, the washer fluid is rated to -25°C, so it's probably not the fluid.

Okay, fluid's ruled out. The heater connector on the Megane is usually near the washer fluid reservoir, often on the washer motor. Given the error codes, it might be best to take it to a workshop to avoid more damage.

Thanks! I appreciate you confirming the connector location. I took it to the workshop on Monday. They found a defective plug connection and fixed it for 95€. All good now.
