According to the manual the lights are not serviceable. Here are the instructions on how to get to the panel so that you can make your own determination on that.
The heated seat switches are located in the center stack of the instrument panel. The switches are located on the outer edges of the accessory switch bank. If either of the switches is damaged or inoperative the complete accessory switch bank assembly must be replaced.
When either of the heated seat switches are depressed a switch status message is sent to the Cab Compartment Node (CCN) or instrument cluster via the Local Interface Network (LIN) data bus. The CCN then sends a message via the LIN data bus to the heated seat module, signaling the module to energize the heating element for the selected seat. Amber Light Emitting Diodes (LEDs) in the top portion of each switch indicate the level of heat in use: Two LEDs are illuminated for high, one for low, and none for off. The heated seat module sends the LED illumination message to the CNN via the LIN data bus. The CNN 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.
The LED indicator lamps in each heated seat switch cannot be repaired. If the LED lamps are inoperative or damaged, or the switch is inoperative or damaged the complete accessory switch bank assembly must be replaced.
See Radio removal instructions in this post. http://www.jeepforum.com/forum/f98/q...5/#post6599929
1. Remove the shifter trim rings (4 and 5)
a. Pull up on shifter knob (3) and remove. (Don't smack yourself in the nose with it).
b. Using trim stick C-4755 or equivalent (plastic knife, spatula, whatever), separate the bezel (4) from the trim ring (5), if manual, also remove the boot.
c. Remove the screws (2) and using trim stick C-4755 or equivalent, separate the trim ring (5) from the shifter console
2. Using a trim stick C-4755 or equivalent, remove the upper trim cover over the center bezel and radio.
3. Using a trim stick C-4755 or equivalent, separate the center bezel from the instrument Panel.
4. Disconnect the HVAC controller electrical connectors (3) and control cables (1 and 9)
HEATED SEAT SWITCH
In 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.
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury or death.
The heated seat switches are integral to the accessory switch bezel and cannot be serviced separately.
1. Disconnect and isolate the negative battery cable.
2. Remove the center bezel from the instrument panel and place it on a work bench
3. Remove the screws that secure the accessory switch bank (4) to the back of the center bezel and remove the accessory switch bank.
