Heated car seats are now a key feature of many modern vehicles. They make driving comfortable during cooler months, adding to the occupants’ convenience. However, heated seats may malfunction in some instances. A blown fuse or broken seat elements may contribute to this problem. For such issues, there are some solutions available for a quick fix.
Here are the common causes of car heated seats not working properly. We have listed down some fixes to help resolve the issue.
Common Causes of Car Heated Seats Not Working
It can be bothersome when heated car seats stop working suddenly. The issue can arise from various electrical or mechanical problems within the seat’s heating system. Here are some common causes of heated seats not heating up. We have also mentioned ways to fix Heated car seats.
Blown Fuse
A blown fuse is one of the simplest and most common reasons for car heated seats not working. The car fuse box protects the electrical circuit from overheating or overloading. However, if it blows, it cuts off power to the heated seat.
This can occur if there’s an electrical surge or if the seat draws too much current. When a fuse blows, the entire seat stops working but other electrical components in the same circuit may also be affected.
HOW TO FIX
To resolve this, check the car’s fuse box (usually located under the dashboard or hood). Refer to the car’s owner’s manual to find the fuse associated with the heated seat. If it’s blown, replace it with a fuse of the same amperage.
If the new fuse blows again shortly after replacement, there may be an underlying issue, such as a short circuit. For that, it is advised to seek professional inspection.
Faulty Heating Element
Another reason for car heated seats not working is a heating element gone bad. The heating element is the core part of the heated seat and can wear out or burn over time due to repeated use. This thin wire or coil embedded in the seat’s cushion generates heat when an electrical current passes through it.
If the element is damaged or broken, the seat may heat unevenly or not heat at all. You may notice that only part of the seat heats up, or it could fail.
HOW TO FIX
Repairing or replacing the heating element often requires removing the seat cover and accessing the element itself. This is usually a task best left to professionals due to the complexity of the repair and the risk of further damage. If the heating element is beyond repair, it may need to be replaced. It may also be more cost-effective than replacing the entire seat.
Damaged Wiring
Wiring issues are common in heated seats due to wear and tear from the constant movement and pressure on the seats. Frayed, broken, or disconnected wires can interrupt the flow of electricity to the heating element. Such disruption is also a sign that your car needs rewiring.
This results in heated seats not warming up. Moreover, wires can get pinched or short-circuited due to improper installation or use over time.
HOW TO FIX
For heated car seats troubleshooting, check the wiring under the seat for any visible signs of damage, such as fraying or loose connections. If you’re comfortable with electrical work, you can attempt to reconnect or replace damaged wires. Otherwise, it’s advisable to have a mechanic or an auto electrician fix the electric problems of a car safely and correctly.
Broken Seat Switch
A broken switch also contributes to the car heated seats not working. The switch that controls the heated seat may wear out over time, leading to unresponsiveness. A malfunctioning switch may not register when you press it, resulting in car heated seats not turning on.
Simply put, it won’t send the signal to activate the seat heating. In some cases, the switch may appear functional but could have internal damage that prevents it from working properly.
HOW TO FIX
The switch can be tested using a multi metre to check if it’s sending power when pressed. If it’s faulty, replacing the switch is usually straightforward and inexpensive.
Control Module Failure
Many modern vehicles have a control module that regulates the temperature and operation of the heated seats. If this module fails, the seat may not heat at all or could overheat. Control module failures can stem from software glitches in car computers, internal electrical problems, or exposure to moisture.
HOW TO FIX
Diagnosing a control module failure may require using specialised diagnostic tools, as the module is tied to the car’s overall electrical system. If the control module is at fault, it will need to be reprogrammed or replaced. However, this is a job for a professional mechanic or dealership, as it may involve resetting the system or updating the software.
Thermostat Malfunction
The car thermostat in a heated seat controls the temperature, ensuring it doesn’t overheat or underheat. If the thermostat fails, it can cause the seat to either stop heating altogether or to become too hot, potentially creating a safety issue. A malfunctioning thermostat may not properly regulate the heat, leading to an inconsistent heating experience.
HOW TO FIX
A faulty thermostat usually requires replacement. This includes removing the seat to access the heating system. Depending on the car model, the thermostat may be into the heating element or located separately.
