Hi, I have a 2014 Grand Cherokee Laredo E. There is a white line at the top of the cupholders that I would expect to light up with the ambient lighting, but does not light up in my truck. Does it light up in others? Is there a way to get lighting in there?

Thanks,

the climate control in this vehicle is/was rather complex. This was one of the first years that tey went to computer controlled climate control and yes, they did have problems or glitches from time to time. One thing that developed very common was the blower running all the time. In most all cases, the ECC power module failed. I suspect this is where your problem lies. this module can? affect other items like fuel data display etc but i can not confirm 100%. I would start by replcing the ECC power module or some call it the blower control module located under the hood, near firewall, passenger side on top of the heater case. You can also unplug it to stop blower. I can not rule out the BCM ( body computer) but more common was the ECC module. The BCM is located on top of the heater case under the dash. To be 1005 sure, a shop can run through a series of diagnostic checks to determine what is at fault. By experience, the blower module has been the problem at least 90% of the time

You say the instrument cluster is out ? You need to have a professional scan tool hooked up ,to see if all modules are communicating ! A code reader isn't going to be any help . If a module isn't communicating could an will bring down the Serial data bus ! Do you know what that is ? An if you replace the instrument cluster ,it has to go to the dealer for programming . An A bcc ,? your vehicle has a Vehicle Security Module ! No GEM , No smart junction box >
NOTE: Prior to removal of the vehicle security module, it is necessary to upload module configuration information to a diagnostic tool. This information needs to be downloaded into the new module once installed. For additional information, refer to Section 418-01 .
The vehicle security module controls the remote keyless entry system and the computer-operated lock system. For additional information, refer to Section 501-14 .
Communications Network Module Communications Network Components

• powertrain control module (PCM)
• restraint control module (RCM)
• instrument cluster
• driver seat module (DSM)
• climate controlled seat module
• parking aid module
• central junction box (CJB)
• vehicle security module
• air suspension control module
• 4-wheel anti-lock brake/traction control (ABS/TC) module or stability assist module
• electronic automatic temperature control (EATC) module
• four-wheel drive (4WD) control module
• power liftgate module
• tire pressure monitoring system module

Principles of Operation
The vehicle has three module communication networks:

• the standard corporate protocol (SCP) communications network
• the international standards organization (ISO) 9141 communications network
• the UART based protocol (UBP) communications network

The diagnostic tool connects to all three networks through the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing one smart tester to be able to diagnose and control any module on the three networks from one connector. The DLC can be found under the instrument panel between the steering column and the radio.
The driver and passenger climate controlled seat modules are on the UBP network. The climate controlled seat modules control the temperature of the driver and passenger seats. For additional information, refer to Section 501-10 .
The vehicle security module is on the UBP communication network. The vehicle security module controls a variety of systems:

• windshield wipers
• courtesy lamps
• warning chimes
• interior lamps
• exterior lamps
• power windows
• perimeter security
• RKE/keyless entry
• lock functions
• monitors the entry doors and radio

Sorry but you would only waste your money buying a code reader ! Your best bet would be to take your vehicle to a qualified repair shop Or the ford dealer .

The data link connector (DLC) allows a scan tool to communicate with the class 2 serial data line. The serial data line is the means by which the microprocessor-controlled modules in the vehicle communicate with each other. Once the scan tool is connected to the class 2 serial data line through the DLC, the scan tool can be used to monitor each module for diagnostic purposes and to check for diagnostic trouble codes (DTCs). Class 2 serial data is transmitted on a single wire at an average of 10.4 kbps. This value is an average; class 2 uses a variable pulse width modulation to carry data and depending on the message it may operate faster or slower. The bus will float at a nominal 7 volts during normal operation. Each module can pull this lower during the transmission. The bus is not at battery positive voltage or ground potential during normal operation. When the ignition switch is in RUN, each module communicating on the class 2 serial data line sends a state of health (SOH) message every 2 seconds to ensure that the module is operating properly. When a module stops communicating on the class 2 serial data line, for example, if the module loses power or ground, the SOH message it normally sends on the data line every 2 seconds disappears. Other modules on the class 2 serial data line, which expect to receive that SOH message, detect its absence; those modules in turn set an internal DTC associated with the loss of SOH of the non-communicating module. The DTC is unique to the module which is not communicating; for example, when the inflatable restraint sensing and diagnostic module (SDM) SOH message disappears, several modules set DTC U1088. Note that a loss of serial data DTC does not normally represent a failure of the module that set it.

Interior Lamps Dimming
This group of interior lighting includes lamps which may be dimmed. This group uses a combination of class 2 controlled illumination and incandescent lamps:
• Air temperature switch
• Cigar lighter lamp
• Door switches
• Driver information center (DIC) switch
• Headlamp switch
• Head-up display (HUD) switch
• Heated seat switches
• HVAC control assembly
• Instrument panel cluster (IPC)
• Memory function switch
• Radio
• Steering wheel controls
• Window switches
For the interior lighting to be dimmed the following conditions must be met:

Here is a discription of how they work ,factory service info.
• A low light level has been detected by the dash integration module (DIM)
• Headlamp switch is placed in to the PARK or HEAD position
• Ignition switch is placed in the ON position
Then all class 2 displays and all incandescent back lighting will be illuminated to the level set by the instrument panel (I/P) dimmer switch. When the I/P dimmer switch is moved from MIN to MAX, all class 2 displays and all incandescent back lighting respond from minimum intensity to maximum brightness.
The DIM supplies battery positive voltage to the coil side of the PRK LP relay in the rear fuse block.
When the I/P dimmer switch is moved from MIN to MAX, then the instrument panel module (IPM), W/CJ2, or climate control panel (CCP), W/C67, applies a message to the class 2 communication circuit to the DIM. The DIM then applies a ground to the park lamp relay control circuit. This energizes the PRK LAMP relay and allows battery positive voltage to be applied through the DIMR fuse to the DIM. The DIM then illuminates the following incandescent lamps through the incandescent dimming output circuit:
• Cigar lighter lamp
• DIC Switch
• Headlamp switch
• HUD switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The DIM also applies a message to the following class 2 controlled illumination components:
• Drivers door module (DDM)
• HVAC control assembly
• IPC
• Radio
The DDM will then send a message through the simple bus interface (SBI) to the RH front door module (RFDM). The door modules will then illuminate the following components through the incandescent dimming output circuit:
• Air temperature switch
• Heated seat switches (W/KA1)
• Memory function switch (W/A45)
• Power door lock switches
• Power window switches
The ground for these components are provided from the DDM and RFDM.
The following components are grounded at G200:
• Headlamp switch
• HVAC control assembly
• Radio
• Steering wheel controls
The following components are grounded at G201:
• Cigar lighter lamp
• DIC Switch
• HUD switch

Having the vehicle checked for DTC'S - diagnostic trouble code's would probably be your best course of action .
DTC B2556 (1)
The I/P dimmer switch is a potentiometer. The instrument panel module (IPM) determines the control setting based on the voltage from the I/P dimmer switch. The IPM sends out a class 2 message to the dash integration module (DIM). The intensity of the interior backlighting shall be adjustable when ever the park lamps are on. The intensity of the vacuum florescent displays shall only be adjustable when it is night and the park lamps are active.

Circuit Description
The I/P dimmer switch is a potentiometer. It is powered by the HVAC control module. The HVAC control module determines the level of dimming desired based on the voltage from the I/P dimmer switch. The HVAC control module converts the I/P dimmer switch feed back voltage to a digital signal and puts it on the Class II communication bus.

Dash Integration Module (DIM)
The DIM is wired to the class 2 serial data line. The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
The DIM functions include the following:
• Control of headlights and exterior lamps
• Horn relay control
• Interior lamps incandescent dimming
• Lamps On signal with wiper/washer
• Power moding control over Class 2 serial data line
• Steering wheel controls
• Storage of the clock settings and, sending a message out on the class 2 serial data circuit in response to requests from other modules
