△ CAUTION
During the installation of the replacement heating element, be careful not to fold or crease the element assembly. Folds or creases will cause premature failure.
ℹ NOTE
Heated seat cushion shown. Heated seat back similar.
ℹ NOTE
Make certain the heated seat wire harness is correctly routed through the seat and seat back. Excess wire between the seat cushion and seat back elements should be securely tucked between the rear of the seat cushion foam and the rear flap of the seat cushion cover.

  1. Peel the adhesive backing off the replacement heating element (2).
  2. Position the replacement heating element directly onto the cushion where the original element was (1). There will be adhesive marks on the cushion, outlining the original heating element location.
  3. Connect the heating element electrical connectors (3 and 4).
  4. Reconnect the negative battery cable.
  5. Verify heated seat system operation.
  6. Install the appropriate seat cushion or seat back cover.

  1. Disconnect and isolate the negative battery cable.
  2. Remove the appropriate seat cushion or seat back cover.
  3. Disconnect the appropriate heated seat cushion or seat back element electrical connectors (2).
  4. Remove the heating element by peeling away from the foam cushion. Be careful not to remove excessive foam from the cushion.
Heated Seat Systemreference
ℹ 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 11.7 volts or above 15.5 volts. Be certain to check the vehicle electrical system for proper voltage anytime the heated seat system appears inoperative.
ℹ NOTE
If a Diagnostic Trouble Code (DTC) can not be verified, it is a good indication that an INTERMITTENT fault condition may be present. To help find an intermittent problem, sit in the seat in question and move around the heating elements within the seat while testing continuity. also wiggle the heated seat wire harness and electrical connectors while testing continuity.
ℹ NOTE
For complete circuit diagrams, see Wiring Information. Wiring Information includes wiring diagrams, connector pin-out and location views, details of wire harness routing and retention, splice and ground locations and proper wire and connector repair procedures.
HEATED SEAT SYSTEM Before testing any individual components in the heated seat system, check the following: -Check the vehicles battery open-circuit voltage and charging system performance. If the vehicle's electrical system is defective or weak it may not be supplying sufficient energy to operate the heated seat system. -Check fuse 9 located in the Totally Integrated Power Module (TIPM). If required, repair the shorted circuit and replace the blown fuse. See Wiring Information. -Using a scan tool, check for any Diagnostic Trouble Codes (DTCs) related to the Heated Seat Module (HSM) and Cabin Compartment Node (CCN). If any DTCs are found, repair as necessary. -If there are no DTCs and the heated seat system functions properly, but one or both of the Light Emitting Diode (LED) indicators in a heated seat switch do not illuminate, replace the accessory switch pod Heated Seat Switch - Removal.

For complete circuit diagrams, see Wiring Information. Wiring Information includes wiring diagrams, connector pin-out and location views, details of wire harness routing and retention, splice and ground locations and proper wire and connector repair procedures.
ℹ NOTE
The wire harness connectors for the heating elements are located under the seat.
ℹ NOTE
When testing the heated seat elements for resistance, be certain to sit in the seat in question and move around the heating elements within the seat while testing. Moving the heating elements will help eliminate the possibility of an intermittent open in the element, which would only be evident in a certain position.

  1. Locate and disconnect the seat electrical connectors as necessary.
  2. Check the resistance between the circuits leading in and out of the suspect heated seat element. The resistance should be between the specifications listed in the following Heated Seat Element Resistance chart. If OK, Heated Seat System. If not OK, replace the inoperative heated seat element Heater Pad - Removal. HEATED SEAT ELEMENT RESISTANCE
Heated Seats - Descriptionreference
⚠ WARNING
The front passenger seat assembly contains critical components that affect the front passenger airbag deployment. Correctly functioning front passenger seat components are critical for the Occupant Classification System (OCS) to properly classify the front passenger and calculate the proper airbag deployment. Unapproved modifications or service procedures to the front passenger seat assembly, its related components, or trim cover may inadvertently change the airbag deployment in case of a frontal crash. This could result in death or serious injury to the front seat passenger if the vehicle is involved in an accident. The following requirements must be strictly adhered to:
Fig. 1
Fig. 1
DESCRIPTION -Do not modify the front passenger seat assembly or components in any way. -Do not modify the front seat center console or center position seat in any way. -Do not use prior or future model year seat trim covers not designated for the specific model being repaired. Always use the correct seat trim cover specified for the vehicle. -Do not replace the seat trim cover with an aftermarket trim cover. -Do not add a secondary trim cover other than those approved by Chrysler/Mopar. -At no time should any Supplemental Restraint System (SRS) component or SRS related component or fastener be modified or replaced with any part except those which are approved by Chrysler/Mopar. Vehicles with the heated seat option can be visually identified by the two heated seat switches (2) located in the center stack (1) of the instrument panel. The heated seat system allows the driver and front seat passenger to select from two different levels of electrical seat heating (high and low). The heated seat system includes the following major components: -Heated Seat Elements - Four heated seat elements are used per vehicle. Two heated seat elements are integral to each front seat, one on each seat back cushion and the other on each seat bottom cushion. -Heated Seat Module - The heated seat module is mounted under the front passenger seat. This module contains the control logic and software for the front heated seat system. The module communicates on the Local Interface Network (LIN) data bus. -Heated Seat Switches - Two heated seat switches are used per vehicle, one for each heated seat. Both switches are mounted in the instrument panel center stack. -Instrument Cluster (CCN) - The instrument cluster, sometimes referred to as the Cab Compartment Node (CCN) utilizes integrated software and information carried on the LIN data bus. The CCN serves as the link between the heated seat switches and the heated seat module.
