Please reply with your model year. the first thing anyone should do Is check the owners guide for what fuse number to look at.

 

same issue

i have the same issue in my 2008 Patriot North edition.
The driver side turns on but doesn't stay on. The passenger side does stay on and works properly. My driver side will work once every million tries. I don't have the owners manual, so im not sure what "fuse to look at"

If it turns on but doesn't stay on it's not a fuse. There is a timer or relay in the circuit that after a period of time switches the setting from "hi" or two lights on on the switch, to "low" or one light on on the switch. Then finally to off after a predetermined amount of time at each selection. You can find an online copy of your owners manual and wiring diagrams that should help you narrow down that timer relay. Once you locate it you can swap the timer relays for the two seats to see if the problem follows the suspect relay. Then you will know for sure prior to ordering or otherwise purchasing the part.

That's, however I had to repost a greater problem! My hazard lights are not working! It seems nothing on that switch bar is working. So, I'm leaving this problem as a secondary issue. My hazard lights are a bigger problem for me.

 

I'll pull the diagram. It could be an intermediate connector inline. I'll post my thoughts on the seat circuit. Are the hazards and the esp disable switches still non functional?

The heated seat module (2) is located under the left front seat. It has a single electrical connector (1) and a push pin style retainer that secures it to the
seat pan. The module can be accessed from under the front left seat with the seat in the full back position.The heated seat module is a microprocessor designed to use the Local Interface Network (LIN) data bus messages from the instrument cluster also
known as the Cabin Compartment Node (CCN). The CCN receives inputs from the heated seat switches and in turn signals the heated seat module to
operate the heated seat elements for both front seats.

Seat Heater Control Module: Description and Operation
OperationOPERATIONThe heated seat module operates on fused battery current received from the ignition switch. The module is grounded to the body at all times through the
electrical connector. Inputs to the module include Local Interface Network (LIN) data bus messages and standard hardwired 12 volt power and ground.
In response to the LIN inputs the heated seat module will control the battery current to the appropriate heated seat elements.When a heated seat switch LIN data bus signal is received by the heated seat module, the module energizes the selected heated seat element. The Low
heat set point is about 38° C (100.4° F), and the High heat set point is about 42° C (107.6° F).In addition to operating the heated seat elements, the heated seat module sends LED illumination messages to the CCN via the LIN data bus. The CCN
then sends the LED illumination message to the accessory switch bank so that the appropriate LEDs are illuminated for any given heating level. Pressing
the switch once will select high-level heating. Pressing the switch a second time will select low-level heating. Pressing the switch a third time will shut
the heating elements off.If the heated seat module detects a heated seat element OPEN or SHORT circuit, it will record and store the appropriate diagnostic trouble code (DTC).

Seat Heater Control Module: Testing and InspectionHEATED SEAT MODULEIn order to obtain conclusive testing, the heated seat system and the Local Interface Network (LIN) data bus circuit must be checked. Any diagnosis of
the heated seat system should begin with, the use of a scan tool and the appropriate diagnostic service information. Refer to the appropriate wiring information for complete circuit schematic or connector pin-out information. NOTE: Vehicles equipped with the heated seat option utilize a low voltage cut-off feature. This feature turns off power to the heated seat
system anytime vehicle voltage is below 11.7v or above 15.5v. Be certain to check the vehicle electrical system for proper voltage anytime the
power seat system appears inoperative.Before any testing of the heated seat system is attempted, the battery should be fully-charged

Check for the module under the driver's seat

There are two connectors under the driver seat between the module and the elements.
One at the module end, and the other that connects the heater elements.

For the power and data to the Seat Heater Module: There is a connector at the driver's seat the connects to the body, then C200 before it lands at the switch. I don't know where C200. IT might be found in the manual on the workshop-manuals.com. Bounce around in "relays and modules" . There may be another circuit that shows you where it is. On Fords, that would be in the dash board somewhere.

 

IS fuse 30 ok at the TIPM. That powers the Heated Seat Module.
IS Fuse 33 OK at the TIPM? That powers the center stack switch pod.

I know you had the TIPM replaced at one point, but a bad heater element or bad Heated Seat Module could blow one or both.

I am running out of ideas. Perhaps the C201 *under dash)or C104 (engine compartment) was jostled or disconnected during the TIPM transplant.

You could use an EVTM or wiring manual. I know what Ford official manuals look like. I can't say the same for Jeep/FCA.

Keep in mind the Hazard Switch won't work either. So it's probably not specifically related to the heated seats. It's probably some common connection under the dash. But locating where that connector is, has been a pain. I just discovered that the Cruise Control Accel button doesn't work either. All these cables must have a common connector somewhere.

Thanks for all the help, really man.

 

OK. I thought that was resolved. Sorry about that.

Let's work on this. Please list all non-functional features and we will find a common link.

Cruise Control Accel and Resume buttons don't work. However SET will.

Hazard, Traction Control and heated seats buttons don't work.

Have tried replacing the Hazard bank of switches and TIPM.

 

All other features and function work w/o fail? C201 appears to be behind the glove box. Light grey connector with 43 pins/cavities

Steering Cruise switches go though C201 too.

Turns do too.

I think you are looking at it the wrong way. I think it's under the driver's side... If you blow up that image you will see the steering column on the right side. So the view is from the outside with the firewall transparent. At least that is what it looks like to me unless this is a european right side drive model. I will try both sides.. so a hunting I will go.

**update** I think I found it. right behind the OBD2 connector. The OBD2 connector seems to be on a hinge or swivel? Is there a way to unlock the hinge so that it swings down?

 

So it's the reverse? It had an arrow with FWD Pointing up to the left. I'm not sure how the obd connector comes out.

There is a relay block under the TIPM. I removed the cover and found only a few relays and a lot of empty sockets. Where do I find out if one of them is related to the hazard lights or heated seats? My Online Haynes manual doesn't seem to have anything on this fuse block.

 

Although the look of my block just has 6 relays placements in it, the positions explained here are consistent with why there is nothing in the spare and turbo positions for mine. So this appears to have nothing todo with my problem.

 

Standard precautions: Turn on headlights and disconnect the battery. The HL should drain any remaining power.


I would break open the C201 Connector and also disconnect the Steering wheel body side connector. I would disconnect the hazard switch.
Take a meter set to Continuity. Probe the connector so that you can test the continuity of the wire from C201 to the endpoint that it connects to.
Example. Heated seats switch. Put one probe on pin 6 red/Light Blue wire, and the other probe at C201 pin 18. IF there is no connectivity. The the other side of the connector. They should be male contact pin on the hazard side of C201. The female terminal pin should be on the TIPM side of C201.
write down if you get connectivity or not. Then move on to the next one.

I wouldn't worry at this point about the other connectors that all the features don't have in common. ie C305, C200, C104, C103.

cruise pin 5, 4, 6 and C201 pin 11, 10, 9, respectively
C103

Heated seats / Hazard switch pin 6 and C201 pin 18
C104
Steering control module pin 2 and C201 pin 1

Heated Seat Module
C305
C200

Cluster CAN BUS
C200



I would also back probe the wires after reconnecting them all. I would check from the TIPM to the endpoint devices to check for total end-to-end connectivity.

You probably have a broken wire in here some where.

 

Here's your fuse relay block for 08. Looks like the spare and the lamp are swapped.

All the connections check out. I'm frustrated.

I think I'm giving up at this point.

I'm considering paying for the dealer diagnosis at $85 an hour. I'm at my wits end with this problem.

Thanks to everyone who helped out with so much information. I could not have gotten this far without you guys.

outtro song rolls in: Another bites the dust - Queen

 

I had same problem finally took it to the dealer.
Found a corroded wire about 15 inches up from the online connector behind the front left inner fender. That is shop discription. 500 bucks to fix a corroded wire. Most wire connections seem exposed. Maybe might start a program of wd-40 spraying connections.

 

What about a continuity test from the switch to the other ends?
