Yes u must de-trim the seat cushion, the element is inside the seat, this is not a job for the novice, get the part yourself and take it to an automotive trim shop.

SOURCE: heated driver seat problem

I just repaired one not long ago.It was a 2001 with heated seats.The first thing you can do is switch the switches to see if the problem moves to the other seat.There are at least three little heaters attached to the foam,that is bonded to the leather.One had a broken wire,the other two [that I know of in the base] tested good.Seems they all have to be working,so everyone must be tested for continuity,with out being pluged in to the others.The only way to see whats going on is to somewhat remove the leather from the seat. With extreme care I was able to get more wire out of the heater and soldier it back on.Then used silicone or 3m window welder around[I don't remember wich] to protect it as that is how it kind of it from the factory. It looked like the wire broke at the edge of the protective part due to sitting on the seat too many times. Bad design,to hold up over time.

It can be done, but for the cost of a new heating element, it is worth the purchase. The replacement for my 2001 I think was ~ 40.00 ( online, plus shipping costs ) for the bottom cushion heating element.

You can take the same amount of work to remove the seat cushion, remove the cover, and try soldering the broken elements ( usually the thigh area in the front ), but you have a used element that is patched. The way I have seen it done, is actually using wire to close the circuit again, not create a new element section.
The seat bottom work is a bit much ( to make sure the cover is on straight and no creases ) to spend the time patching vs. replacing what is a fairly cheap part.
You can try Tasca and Southwest ford parts online for the current element pricing.
Depending on the shape of the cover and cushion itself, you might consider replacing those ( or the cushion ) as long as you have it apart, but this is getting a bit expensive ( would be ~ 200.00 for all 3 new ).
I did the cushion at the same time, and it made the world of difference to the feel of the seat, just like the day it came out of the factory.

Hi, I have a 2001 Mazda Millenia S. The light for my heated seats come on, but there is no heat in either the driver's or passenger's seat. What could be the problem?


Mazdas are pretyy bad about the seat heating elements burning out. To verify that the problem is not the circuits to the elements, remove the 4 bolts holding the seat to the floor and tilt the seat back. Find the 2 pn connector for the heating element under the seat. (On the driver's side it will have a White and Red wire and a Yellow and Red wire. On the passenger side it will have a White and Red wire and a Green wire) Disconnect the connector. Using a standard 12 volt test light and a paper clip, use the paper clip to connect on end of the test light to the White and Red wire and probe the Yellow and Red (or the Green wire) with the test light probing end. With the ignition switch on and the seat switches turned on, the test lamp should light up. If it does, you need to replace the heating element in the seat. If it does not light up, post a comment to let me know, and I'll talk you through diagnosing the heater circuits.

Driver side seat heater light comes on and goes right out seat wont heat up passenger side works fine


The problem lies in the drivers side seat, the heating element for the back of the seat or the seat heating element has an open or shorted circuit. the part from ford will run you about $150.00 dollars.

2005 hyundai tucson v6 passenger side heated seat will not warm up the light comes on. driver side is ok could it be the switch even if the light comes on


Possibly.... the only way I know to diagnosis this issue is with an amp meter in the circuit that heats the seats. Compare LH & RH seat heating current draw. If you find the pass seat is NOT drawing the same amount of current, further troublshooting is required. There are TWO heating elements installed in the seats -- seat bottom & seat back, and they are connected in 'SERIES'... so if either element goes/is 'OPEN', then it's component replacement time. There is a thermostat in the heating elements -- it regulates the seat temperature. One must isolate the two elements & check each one individually (seat bottom - checking resistance... and seat back - checking resistance). whichever one (or possibly both) are 'OPEN'. If you find resistance is normal (3 to 5 ohms), then the problem/cause may be in the switch (or its contacts). Using a test light (12 volt bulb), check for power (battery voltage) at the heating element connector to ground (chassis). If the bulb lights up, you know you have power at the switch and is sending it to the heating elements.

My drivers side heated seat doesn't heat up anymore but the light on the switch lights up


this sounds like a bad heating element in the seat, you will need to test for power and ground at the connection going to heat element, if theres power and a good ground then the element is bad, you will need to remove the seat and take the covering back to remove element.

Bottom portion of passenger heated seat not working, but the back heated cushion is working normally. The lights for the seat warmers in both activation switches are illuminated when selected.


It sounds like the heating element is broken. Unfortunately they don't usually tell you that if you have heated seats, kneeling or stepping on them, even briefly (as if you were leaning in to get something from the car), or putting something heavy with a firm edge (like a heavy box), can sometimes break one or more of the wires in the heating element. I'd be willing to bet that this is what has happened. The heating elements in the seat are wired together, so it's not a case of having a heat control module for the cushion dying while the one for the backrest is OK. If the whole seat stopped heating, I'd think about looking into the controls for the seat, but with part of it still working, it's likely that the cushion heater has been damaged and will have to be repaired or replaced.

I will post it in 2 different posts because its too long DB

HEATED SEAT SYSTEM
Individually controlled driver and passenger side electrically heated front seats are available factoryinstalled optional equipment on this model, when it is also equipped with the power seat option. The heated seat system allows both the driver and the front seat passenger the option to select one of two seat heating ranges, Low or High, or to turn the individual seat heaters OFF using the heated seat switches located in the center lower bezel near the bottom of the instrument panel center stack. The heated seat switch circuit operates on ignition switched battery current supplied through a fuse in the junction block, only when the ignition switch is in the ON position.

The heated seat system consists of the following components
  • Heated seat elements
  • Heated seat sensors
  • Heated seat module (or memory heated seat module)
  • Heated seat switches.
The heated seat system also relies upon resources shared with other electronic modules in the vehicle over the Programmable Communications Interface (PCI) data bus network. The PCI data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, internal controller hardware, and component sensor current loads. At the same time, this system provides increased reliability enhanced diagnostics, and allows the addition of many new feature capabilities. For diagnosis of these electronic modules or of the PCI data bus network, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended.

The electronic modules that may affect heated seat system operation are as follows:
  • Body Control Module (BCM) - Refer to Body Control Module in Electronic Control Modules for more information.
  • Heated Seat Module (HSM) - Refer to Heated Seat Module in Electronic Control Modules for more information.
  • Memory Heated Seat Module (MHSM) - If the vehicle is equipped with the Memory System, refer to Memory Seat Module in Electronic Control Modules for more information.
Refer to Power Seats Premium I/III in the Contents of Wiring Diagrams for complete circuit diagrams. Following are general descriptions of the major components in the heated seat system.

The heated seat system will only operate when the ignition switch is in the ON position, and the surface temperature at the front seat heating element sensors is below the designed temperature set points of the system. The heated seat system will not operate in ambient temperatures greater than about 41 °C (105 °F) . The front seat heating elements and sensors are hard wired to the Heated Seat Module (HSM) or the Memory Heated Seat Module (MHSM).

The heated seat switches are hard wired to the Body Control Module (BCM). The BCM monitors the heated seat switch inputs, then sends heated seat switch status messages to the HSM or MHSM over the Programmable Communications Interface (PCI) data bus. The HSM or MHSM contains the control logic for the heated seat system. The HSM or MHSM responds to the heated seat switch status messages, ignition switch status messages, and the front seat heating element sensor inputs by controlling the output to the front seat heating elements through integral solid-state relays.

When a seat heater is turned ON, the sensor located on the seat cushion electric heater element provides the HSM or MHSM with an input indicating the surface temperature of the seat cushion. If the surface temperature input is below the temperature set point for the selected Low or High heated seat switch position, the HSM or MHSM energizes the integral solid-state relay, which supplies battery current to the heating elements in the seat cushion and back. When the sensor input indicates the correct temperature set point has been achieved, the HSM or MHSM de-energizes the solid-state relay. The HSM or MHSM will continue to cycle the solid-state relay as needed to maintain the temperature set point.

The HSM or MHSM and the seat heater elements operate on non-switched battery current supplied through the power seat circuit breaker in the junction block. However, the HSM or MHSM will automatically turn OFF the heating elements if it detects an open or short in the sensor circuit, a short or open in the heating element circuit causing an excessive current draw, or when the ignition switch is turned to the OFF position.

See the owner's manual in the vehicle glove box for more information on the features, use and operation of the heated seat system.
