What do I look for to fix the Power seats and power tilt steering has no power


A control module ! Electronics The steering column has a tilt/telescoping control system that consists of an electronic control module capable of class 2 serial data communication, a steering column power assembly with positioning motor and sensor, and a steering column control switch. The multi-function lever provides for the control of the headlamp high beams, and the windshield washer and wiper.
The tilt/telescoping steering column in/out/up/down switch is an input to the driver position module (DPM). The tilt/telescoping drive motor is an output function of the DPM.
Steering column memory settings are stored in the DPM. The steering column position sensor is an internal part of the tilt/telescoping motor assemblies, and is an input to the DPM. The DPM uses the position sensor input when storing and recalling memory settings.
Same thing with the seats , electronic control module .
Battery positive voltage is supplied at all times to the memory seat module (MSM) through the battery positive voltage circuit from the POWER SEATS circuit breaker located instrument panel (I/P) fuse block. This voltage is used to power up MSM and also to apply power to the seat motors when commanded. Battery positive voltage from the TILT/TELE SW/MEM SEAT MOD fuse located in the body control module (BCM) fuse block that supplies voltage to the seat adjuster switch and the memory function switch, also supplies voltage to the MSM. The MSM monitors this voltage circuit in order to determine if battery voltage is supplied to the seat adjuster switch. The MSM is grounded through the module ground circuit and G301.

The driver's side heated seat won't turn off on my 2003 Mecury Moutaineer. Also, how do I change my cabin filter?


Your vhicle build date is on a blue sticker on the driver door or door frame. If not there, check other doors.
The heated seat Module is under the seat. You can unplug the connector on it or the heated seat switch to shut it off. I supect the module is bad. get one used from car-parts.com. The cabin air filter is under the leaf screen at the base of the windshield. Remove wiper arms and leaf screen for access. Please rate, thanks. Principles of Operation - Heated Seats - Vehicles Built 03/2002 Onward
NOTE: Two heated seat modules are used, one for vehicles built up to 03/2002 and one for vehicles built 03/2002 onward. The modules are not interchangeable.
The driver and passenger heated seats share a common battery and ignition feed. A shared ground source supplies the heated seat control switches. When the heated seat control switch is pressed with the ignition switch in RUN or START, a momentary ground signal is sent to the heated seat module. The heated seat module then supplies power to the heating element circuit. The cushion element and seat backrest element are wired in series and powered by the same output. The heated seat module also will ground the separate indicator circuit at the dual automatic temperature control (DATC) module display panel to indicate an ON state. The heated seat module will remain on until the heated seat control switch is pressed and a momentary voltage signal is received, or until 10 minutes expire. If the ignition source is removed from the module, the heated seat module will enter an OFF state and will not return to ON until the switch is once again pressed with the ignition switch in RUN. The heated seat module is designed to heat the seat to 37.5?C (99.5?F) and maintain the temperature until time-out or switched off. This temperature is maintained by the heated seat module monitoring the temperature sensor located in the seat cushion element, and adjusting the current flow to the heating elements.

My power driver's seat 1999 lincoln continental keeps returning to the full back position even when i drive.I changed the entire seat frame with new motors and gears, $500.00 no fix. I have to pull the #39...


does this have automatic seat positioning when you open the door or hit the unlock button on your key fob?

here's how it works:

Seats — Programmable
The memory seat system allows automatic positioning of the driver seat to two programmable positions using the message center, the key fob or the keypad on the door.
Seats — Driver Seat Module
The Driver Seat Module (DSM) is located under the driver's seat and is attached to the seat frame. The DSM will:
  • control the movements of the driver's seat and power exterior rearview mirrors
  • store and recall seat and mirror positions of two personalized settings
  • receive all power seat and mirror control inputs from the Driver's Door Module (DDM) through the J1850 communication network
  • move the exterior rearview mirrors downward when the transmission is shifted into reverse, if enabled.
Seats — Driver Door Module
The driver's seat regulator control switch is connected to the Driver Door Module (DDM). The DDM receives the driver's seat regulator control switch input and communicates the direction of movement over the J1850 communication network.
-----------------------------------------------------
Visual Inspection Chart Mechanical Electrical
  • Front seat tracks obstructed.
  • Seat at limit(s) of travel.
  • Open fuse junction panel Fuses 39 (10A), 41 (20A), and 28 (10A).
  • Open power distribution box Fuse 13 (30A).
  • Loose, corroded or damaged connectors.
  • Damaged switches.
  • Damaged motors

------------------------------------------------
Also, the dealer can run a scan on your seat modules with his tester and tell you what the codes are. They should only charge an hour to do this. Then you can decide what to do. Call your dealer and ask how much to run the scan test.

2002 Grand Cherokee Heated Seats don't work


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.

2006 Lincoln Navigator. My driver side heated seat is flaking out. I turn it on after starting the vehicle and it comes on for about 20 seconds and then shuts off. If i push the button a second time it...


Electronics involved !
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 dual automatic temperature controller (EATC) located on the instrument panel. Each front seat temperature is then monitored and controlled by the dual climate control seat module (dual CCSM) located underneath the passenger front seat cushion.

Both the driver and front passenger climate controlled seats are independently controlled electronically by the dual climate controlled seat module (CCSM) 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 dual CCSM, diagnostic testing can be carried out with the ignition switch key ON engine OFF (KOEO). The system receives power from central junction box (CJB) fuse 118 (30A) through circuit 1153 (RD/BK) feeding battery voltage into dual CCSM C3265b pins 1 and 24. If power is disconnected from either pin 1 or 24 of dual CCSM C3265b, only 1 seat will be disabled (pin 1 for driver seat, pin 24 for passenger seat), the other will remain operational. Since 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.

Sorry , but it would be best for you to take it to the dealer or someother qualified repair shop.
