climate-controlled seats

I have a 2007 Expedition with climate controlled seats. Driver and passenger both just stopped working one day(heat and cool), the light will come on for just a second then go off. If anyone else has ever had this problem please let me know what you found out.

INOPERATIVE OR NO COMMUNICATION WITH DUAL CLIMATE CONTROL SEAT MODULE (DCSM)
FORD:
2007-2008 Expedition

LINCOLN:
2006 Zephyr

2007-2008 MKZ, MKX, Navigator
ISSUE
Some 2007-2008 Expedition and Navigator, 2006 Zephyr and 2007-2008 MKZ vehicles may exhibit inoperative climate seat function with no communication to the DCSM due to a ground concern.

ACTION
Follow service procedure to correct concern.

SERVICE PROCEDURE
NOTE THIS PROCEDURE ONLY APPLIES IF DAMAGE HAS BEEN IDENTIFIED AT THE SPECIFIC CONNECTOR AND PIN. IF DAMAGE IS NOT VISIBLE AT THE SPECIFIC CONNECTOR AND PIN, THIS PROCEDURE DOES NOT APPLY AND CONTINUE WITH NORMAL DIAGNOSTICS IN THE APPROPRIATE WORKSHOP MANUAL.

Refer to Workshop Manual (WSM), Section 501-10 to gain access to the DCSM connector. Seat removal may be required.

Zephyr-MKZ:



If Connector C3305A is damaged at Pin M GD139 (BK-YE), then replace connector pigtail. The replacement pigtail will have an extra wire in Pin L position. (Figure 1)
1. Obtain Pigtail Kit. Strip the ends of the wires from Pins L and M, 1/4" (6.3 mm). Twist them together. Insert twisted wires into one end of a 12-10 gage butt splice. Using the approved splicing methods found in the Wiring Diagram (WD), Cell 5, crimp the butt connector.

2. Strip the end of GD139 (vehicle harness side - ground) and insert into open end of the 12-10 butt splice (at Pin M). Using the approved splicing methods found in the WD, Cell 5, crimp the butt connector and seal with shrink tubing.

3. Continue to attach the rest of the pigtail wires to the vehicle harness, using the approved splicing methods found in the WD, Cell 5, crimp the butt connector and seal (with shrink tubing). Wires from pins E and F will require 12-10 butt splice which is not included in the pigtail kit.

Expedition-Navigator:

If Connector C3265A is damaged at Pin M GD138 (BK-WH), then replace connector pigtail. The replacement pigtail will have an extra wire in Pin L position. (Figure 1)
1. Obtain Pigtail Kit. Strip the ends of the wires from Pins L and M, 1/4" (6.3 mm). Twist them together. Insert twisted wires into one end of a 12-10 gage butt splice. Using the approved splicing methods found in the Wiring Diagram (WD), Cell 5, crimp the butt connector.

2. Strip the end of GD139 (vehicle harness side - ground) and insert into open end of the 12-10 butt splice (at Pin M). Using the approved splicing methods found in the WD, Cell 5, crimp the butt connector and seal with shrink tubing.

3. Continue to attach the rest of the pigtail wires to the vehicle harness, using the approved splicing methods found in the WD, Cell 5, crimp the butt connector and seal (with shrink tubing). Wires from pins E and F will require 12-10 butt splice which is not included in the pigtail kit.

MKX:

If Connector C3036A is damaged at Pin M GD145 (BK-WH), then replace connector pigtail. The replacement pigtail will have an extra wire in Pin L position. (Figure 1)


1. Obtain Pigtail Kit. Strip the ends of the wires from Pins L and M, 1/4" (6.3 mm). Twist them together. Insert twisted wires into one end of a 12-10 gage butt splice. Using the approved splicing methods found in the Wiring Diagram (WD), Cell 5, crimp the butt connector.

2. Strip the end of GD139 (vehicle harness side - ground) and insert into open end of the 12-10 butt splice (at Pin M). Using the approved splicing methods found in the WD, Cell 5, crimp the butt connector and seal with shrink tubing.

3. Continue to attach the rest of the pigtail wires to the vehicle harness, using the approved splicing methods found in the WD, Cell 5, crimp the butt connector and seal (with shrink tubing). Wires from pins E and F will require 12-10 butt splice which is not included in the pigtail kit.

NOTE IF PIN M IS DAMAGED ON THE MODULE THE DCSM MAY NEED TO BE REPLACED.

CLIMATE CONTROL SEAT FUNCTION
INOPERATIVE - NO COMMUNICATION - DCSM -
VEHICLES BUILT PRIOR TO 8/31/2007

FORD:
2007-2008 Expedition

LINCOLN:
2006 Zephyr
2007-2008 KZ, Navigator

ISSUE
Some 2007-2008 Expedition and Navigator, 2006 Zephyr and 2007-2008 MKZ vehicles built before 8/31/2007 and equipped with climate control seats may exhibit inoperative heating and/or cooling. There are no diagnostic trouble codes (DTCs) associated with this issue and IDS/PDS will not communicate with the dual climate control seat module (DCSM).

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE
1. Turn the ignition switch to key on engine off (KOEO) position.

2. Run self test on DCSM.

a. If DTCs are present do not continue with this TSB, follow normal Workshop Manual (WSM) diagnostics for the DTCs.

b. If no communication with the DCSM, proceed to Step 3.

3. Remove power to the DCSM and wait a minimum of 2 minutes. This will reset the DCSM.

^ Expedition/Navigator - remove Fuse 8 in the battery junction box (BJB).

^ Zephyr/MKZ - remove Fuse 11 and 12 in the BJB.

4. Reinstall the fuse(s) and recheck for communication.

a. If communication does not return, refer to WSM, Section 418-00.

b. If the communication is restored by resetting:

(1) Expedition/Navigator/2008 MKZ - reprogram the DCSM to the latest calibration using IDS release 51.4 or later with patch 7. Calibration files may also be obtained at the website.

(2) 2006 Zephyr/2007 MKZ - replace the DCSM.

5. Recheck operation of the heated/cooled seat and for DTCs. If no DTCs return the vehicle to the customer.

2. Select "Toolbox" at the top of the screen.

3. Select "Module Programming" from the menu.

4. Select "Programmable Parameters".

5. Select "Climate Control Seats".
