1. Faulty seat control module: The seat control module is responsible for controlling the heating and cooling functions of the seat. If it is faulty, it may cause the seat to function improperly.
2. Wiring issue: There may be a problem with the wiring that connects the seat control module to the seat heating and cooling elements.
3. Faulty seat heating and cooling elements: The heating and cooling elements in the seat may be faulty and not functioning properly.

To fix this issue, you will need to diagnose and troubleshoot the problem. This may involve checking the wiring, testing the seat control module, and inspecting the seat heating and cooling elements. It is recommended to have a mechanic or dealership technician diagnose and fix the issue, as they will have the necessary tools and expertise to properly troubleshoot and repair the problem.

Tried resetting fuse's ????? how do you reset a fuse ?

The climate control seat system is able to heat and cool the front seats. Each climate controlled seat is operated by push-buttons on the EATC module located on the instrument panel. Each front seat temperature is then monitored and controlled by the dual climate control seat module (DCSM) located on the passenger front seat track.
The climate controlled seat system contains the following components:

• EATC module
• DCSM
• Thermo-electric device (TED) and blower assembly within each front seat cushion and backrest
• Air filter (attached to each TED and blower assembly)
• Cushion and backrest manifolds
• Cushion and backrest foam pads
• Cushion and backrest trim covers
• YOUR best bet , take it to a qualified repair shop . Unless you have factory service repair info. an a professional scan tool , This heated an cooling seat system can set DTC'S - diagnostic trouble codes in the heated seat module .

Climate Controlled Seat System
NOTE: When installing a new dual climate control seat module (DCSM), it is necessary to carry out programmable module installation (PMI). For additional information, refer to Section 418-01 .


Both the driver and front passenger climate controlled seats are independently controlled electronically by the DCSM mounted to the bottom of the passenger seat cushion. The climate controlled seat system only operates with the engine running, however, if using a diagnostic tool to command the DCSM, diagnostic testing can be carried out with the ignition switch key ON engine OFF (KOEO). The system receives power from battery junction box (BJB) fuse 12 (30A) feeding battery voltage on circuit SBB12 (GN/RD) into DCSM C3305a pin F. The system also receives power from BJB fuse 11 (30A) feeding battery voltage on circuit SBB11 (BU/RD) into DCSM C3305a pin E.
If only one of the BJB fuses 11 or 12 open, both seats will remain operational because the power feed circuits are internally connected in the DCSM.
Both climate controlled seats operate independently. If a fault occurs setting a DTC specific to either climate controlled seat, only the affected seat will be disabled by the module and the other will remain operational.
The 4 switches (identified with seat icons) on the dual-zone electronic automatic temperature control (EATC) module activate each seat system setting and illuminate LEDs above each switch to indicate the operating mode, 3 LEDs for HIGH, 2 LEDs for MED or 1 LED for LOW. The push-buttons with the blue seat icon operate the seat cooling mode and the push-buttons with the red seat icon operate the seat heating mode. The climate controlled seat system is not equipped with auto-mode.
Each driver and front passenger seat cushion is equipped with a thermo-electric device (TED) assembly that includes a seat blower (fan motor, serviced as an assembly with the TED). Similarly, each driver and front passenger seat backrest is also equipped with its own TED assembly with blower. Cabin air is drawn through the blower and distributed to each of the TED modules located in the seat cushion and backrest. The TEDs then heat or cool the air. The air is then directed into the foam pad and manifold where it is distributed along the surface of the cushion and backrest of the seat. Once the system is activated, the DCSM uses a set of flexible algorithms to control the heating/cooling modes and the blower speed dependant on the EATC seat switch settings.

The TED uses a ''Peltier'' circuit of P-type and N-type semiconductors connected in series using copper electrical conductors. The semiconductors are sandwiched between 2 copper heat exchangers. When current is applied to the TED, one side releases energy as heat, while the opposite side absorbs energy and gets cold. By reversing the current flow, the hot and cold sides reverse.
NOTE: Avoid applying power directly to a TED for testing its operation. Doing so may cause damage to the TED or shorten its usable life.
The temperature differences between the individual heated and cooled settings is minimal. For example, it is difficult to distinguish between LOW COOL and MEDIUM COOL settings. Measuring seat temperature at different settings is possible by monitoring the DCSM PIDs using the diagnostic tool.
The EATC module communicates climate controlled seat commands to the DCSM using the medium speed controller area network (MS-CAN) communication bus. The MS-CAN bus is connected to the data link connector (DLC) for diagnostic use. No direct connection exists between the DCSM and EATC for the climate controlled seat switches. The climate controlled seats can be commanded using the diagnostic tool to verify both module communication on the MS-CAN bus and operation of the DCSM. This method may be useful for isolating a control switch concern. It should also be noted that because CAN bus communication is more robust and reliable than other methods, it may be possible to have limited module communication with one of the CAN bus circuits disconnected or shorted to ground. Refer to Section 418-00 for additional information concerning CAN bus communication.

Air Circulation
When the heated/cool seat switch is pressed to initiate operation of the climate control seat (CCS) system, cabin air is drawn through the heated/cool ventilation module air filter, then directed through passages in the foam of the seat cushion and seat back to the seat's occupant. In order for the CCS system to operate to its optimum performance, it is crucial to have unrestricted air flow through the system. A dirty or restricted air filter, the blockage of an exhaust air duct, a misaligned heated/cool ventilation module, or incorrect foam installation of the seat cushion or seat back will all have negative effects on CCS operation.
Heated/Cool Ventilation Module
Each heated/cool seat has 2 ventilation modules, one located under the seat cushion and one located in the seat back. These modules are controlled by the climate control seat module (CCSM). Each ventilation module contains a thermo-electric device (TED), a temperature sensor, and a blower motor. The TED and temperature sensor are mounted downstream of the blower motor. Each TED consists of a circuit of positive and negative connections sandwiched between 2 ceramic plates. Each ceramic plate is equipped with copper fins for heat exchange. The air flowing past these fins is either directed as conditioned air into the seat cushion and seat back, or directed into the cabin as waste air.
A TED is essentially a solid state heat pump that is used to heat or cool the air supply to the seat cushion and seat back. When voltage is applied to a TED, one side releases energy as heat, while the opposite side absorbs energy and gets cold. When the polarity of the current flow to the TEDs is switched, the hot and cool sides of the TED reverse.
During the following climate control seat system description and operation, the TEDs, blower motors, and temperature sensors will be referenced independently even though they are all packaged together as a module.
Climate Control Seat (CCS) System
The CCS system consists of two heated/cool ventilation modules and one climate control seat module (CCSM) that controls both the driver and passenger heated/cool seats systems. The CCSM is mounted below the front passenger seat cushion. It receives power from both, battery positive voltage and ignition 3 voltage.
Once a CCS system is activated, cabin air is drawn through the seat blower motors and directed across the fins of each of the thermo-electric device (TED) located under the seat cushion and in the seat back. The air is either heated or cooled as it passes over the TEDs. This conditioned air is then directed through channels in the foam of the seat pad and through small holes in the seat cover to the occupant. Once the system is activated, the CCSM uses a set of algorithms to control the temperature of the selected heating or cooling modes.
Your best bet is to take your vehicle to a qualified repair shop an have it diagnosed .

Sorry

The most common cause of this problem is that the drivers seat heater grid is open or burned out. That is based on 25 years as a Ford dealer technician.

there is a heat /cool control module under the drivers seat.

The following checks and repairs can help you:
1. In the fuse box within the bonnet - check fuse number 22, if burnt, replace it
2. Check fuse 19 in the fuse box inside the car located under the dashboard on the driverside
3. If these steps don't help, the problem may be with the wiring and connection between the module and the seat cushion - inspect it
4. Check if the signal return on the circuit is adequately functioning - if the module is being informed of an active seat
5. If there is a problem - repair or replace the circuit and/or wiring.

The seat switch or the heated seat relay is bad.Always check your fuses first.

You may try cleaning the filters and checking for loose connections. Heat and cooling filters should be changed or cleaned with some regularity. Like an air conditioner, these things require maintenance that are often overlooked.
