Seat Leon Climate Control and Blower Issues

I own a 2014 Seat Leon with a Diesel engine and 150,000 km on the clock. I'm experiencing persistent issues with the climate control system. After an MOT, the car's heating wouldn't stop and only cut off when the battery went low. I've checked the fuses and blower heater, and they seem fine. The air regulation light won't stay on when it's constantly blowing. I replaced the climate control panel as a mechanic suggested the message wasn't getting from the controls to the fan. It worked for two weeks but then stopped again. An electrical mechanic looked at it, and it started working after two months but only for a day or so. It either completely stops working or goes constantly until the battery is low. I have a young child, and with winter approaching, I need help resolving this issue. Any advice or suggestions would be greatly appreciated.

The 2014 Seat Leon is experiencing persistent climate control issues, where the heating won't stop and drains the battery, or it stops working entirely. Possible causes include faulty wiring or a malfunctioning relay, as the problem is intermittent and sometimes resolves temporarily after hitting a pothole. Suggested solutions involve checking wiring connections for security and corrosion, inspecting relays, and documenting when the issue occurs to aid diagnosis.

It sounds like there might be an issue with the climate control system's wiring or a faulty relay. Start by checking the wiring connections to ensure they are secure and free from corrosion or damage. Pay special attention to the connections at the climate control unit and the blower motor. If the wiring seems fine, consider inspecting the relays associated with the climate control system, as a faulty relay could cause intermittent operation. Given the safety concerns with a young child and the potential for the battery to drain, it's important to address this promptly. If you're not comfortable with these checks, I recommend having a professional mechanic take a closer look. Let me know how it goes or if you have any further questions.

Thank you. I will ring my mechanic tomorrow. The only problem is that when he looks at the car, it will be working perfectly and he won’t be able to check why no air blowing out.

Consider asking your mechanic to perform a thorough inspection of the climate control system, focusing on the wiring and relays even if the system is currently working. Intermittent issues can often be traced to loose connections or faulty components that may not always show symptoms. It might also be helpful to document when the problem occurs, such as specific conditions or times, to provide more context for the mechanic. Let me know if you need further assistance or have any questions.

Sometimes if I go over a pothole it might start working or driving along the road it will randomly start. Sometimes after the air blower has been blowing overnight , the coolant levels will have decreased.

Sometimes if I go over a pothole it might start working or driving along the road it will randomly start. Sometimes after the air blower has been blowing overnight , the coolant levels will have decreased.

This suggests there might be a loose connection or a short in the wiring that gets temporarily fixed with movement. Additionally, the decrease in coolant levels could indicate a leak or another issue with the heating system. Check for any visible signs of coolant leaks under the car or around the engine bay. Given the complexity and potential safety concerns, especially with the coolant loss, it's crucial to have a professional mechanic inspect the vehicle thoroughly. Please keep me updated on your progress or if you have more questions.
