2007 Buick Lucerne CXL: Cooled seats not working. LIghts come on, temperature adjusters work but the motors under the seats do not come on.


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 .

  1. Ignition OFF, disconnect the C1 harness connector at the CCSM.
  2. Test for less than 5 ohms between the ground circuit terminal M and ground.
  3. ?‡'
    If greater than the specified range, test the ground circuit for an open/high resistance.

  4. Verify that a test lamp illuminates between the B+ circuit terminal E and ground.
  5. ?‡'
    If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

  6. Disconnect the C2 harness connector at the CCSM.
  7. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 1 and ground.
  8. ?‡'
    If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.

  9. If all circuits test normal, replace the CCSM.

Where are relays for heated seats in 2004 monte carlo ss


Hi jkelley, I'm glad to help!

Usually in most cases when the heated seats quit working its the heated seat element that you sit on under the padding. Here's what I want you to do: Turn the key on then push the heated seat on button and see if it lights up. This is a quick test but not always an accurate test because the switch could still be working but the LED Light could be bad. BUT, in most cases this is a good test. If it lights up then its safe to say that its mostly likely the ELEMENT that's bad. Most of the time if you'll raise the seat cover you'll see that the element is burnt. Hope this helps and have an awesome day.

How can I find out what has gone wrong with my headed seat? On/off switch lights, but seat doesn't get warm. This first began with the seat getting too warms at times, now nothing. Thank you in...


The most common problem with these heated seats and all heated seats is the actual heater grid in the seat... it is basically like a heating pad that you have in your house except thinner and smaller, these grids usually will shot out causing the syptom that you stated the seat will seem to get really hot and then just quit working all together if you disconnect the connector for the heater grid and it has power and ground than the grid is bad the connector is usually a two pin connector under the seat.... What ever you do do not unplug any Yellow connectors as they are for the air bag system... If you need more information let me know i will be happy to help

Both of the front seat heaters run off of the same 2 fuses, so the problem is not a fuse if the passenger seat is working. Each seat has a separate electronic control module, so a bad driver's seat module could be the problem. The seatalso has 2 elements - onefor the seat cushion and one for the seat back. If one is heating and the other is not, then the problem is probably a failed element. If neither element is heating, then the moduleis most likely at fault. The modules in the seats are controlled by the Body Control module (BCM), so the problem could also be a fault in the class2 data circuit between the BCM and the driver's seat module.

In any case, a scan of your BCM will probably yield a fault code that will lead you in the right direction.

Here is a heated seat TSB for cars built prior to 12/14/07

TSB 09-4-8
03/09/09
INOPERATIVE HEATED SEAT(S) - BUILT
BEFORE 12/14/2007

FORD:
2005-2007 Five Hundred, Freestyle
2008 Taurus X, Taurus

MERCURY:
2005-2007 Montego
2008 Sable

ISSUE
Some 2005-2007 Freestyle, Five Hundred, Montego and 2008 Taurus, Sable and Taurus X vehicles built before 12/14/2007 may exhibit an inoperative heated seat(s). This concern may be caused by an intermittent open element in the heated seat mat.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE
The heated seat system is controlled by the heated seat module located underneath the front passenger seat cushion. The heated seat switches are part of the heating ventilation air conditioning (HVAC) module but the heated seat system operates independently from the climate control system. The heated seat module regulates seat temperature by monitoring resistance of a thermistor type thermostat located in the cushion heater mat. The heated seat module is designed to remain on, heating the seat and maintaining temperature until switched off. For vehicles built before 5/1/2006, the module will time-out and switch off after 10 minutes.

1. Refer to Workshop Manual (WSM), Section 501-10 for pin point test on inoperative heated seat(s).
a. When testing the heater mats resistance and circuits for an intermittent open, technicians should sit in the seat while testing the circuit resistance, move the seat in multiple seating positions and apply pressure to several areas of the heated seat mat to ensure the mat element is not open intermittently.

2. Refer to WSM 501-10 for heated seat element replacement when an open electrical circuit has been identified.

Parts Block
