INSTRUMENT PANEL LIGHTING

The instrument panel lights (miles driven, warning messages, etc) are bright occasionallyh and sometimes so dim that it is nearly impossible to read the message, or temperatoure, or warning message etc. This changes while driving on a cloudy day,. Could it be a fuse?

    I have the same problem with my 2006 La Crosse and always forget to inform the technicians upon service.

    I have the same problem on my 2005 LaCrosse, with the instrument lights being real dim some days, and not on other times. Sometimes the lights get brighter when I'm driving. Like today, they stayed real dim and never got any brighter. I'm thinking it's in the Multi-Function switch, (aka malifunction switch) All this is in the wiper arm lever, turn signals, brake lights, washer, etc. And I might add, it will cost about $500.00 to replace with a new switch.

How do i bim and brighten dash light 2002 buick lesabre


bim or DIM ? the dimmer switch ! Interior Lamps
The interior lamps consists of two groups, lamps that can not be dimmed and lamps that can be dimmed. This first group consists of lamps that may not be dimmed. This includes those lamps that may be manually turned on by placing the interior lamp switch to the DOME position, or by opening a door or a compartment:
• Door courtesy lamps
• Footwell courtesy lamps
• Instrument panel (I/P) compartment lamp
• Overhead console courtesy lamps
• Reading courtesy lamps
• Rear compartment courtesy lamp
• Roof rail courtesy lamps
• Sunshade vanity mirror lamps

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:
• 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
• IPC
• Radio
• Steering wheel controls
The following components are grounded at G201:
• Cigar lighter lamp
• DIC Switch
• HUD switch

When I turn on my head lights my dash board goes dark. Turn off headlights the dash lights come back on. Any ideas what is causing this?


Check where the brightness adjuster is for your instrument panel lighting on your vehicle because there will be one. Sounds from what you have said that this is being moved each time you are turning on and off the headlights because they are totally separate controls.

Which fuse is for the instrument panel back lighting?


Does the radio play ? Are any other back lighting components not lighting ? Does the HVAC control panel light up ? You probably need new radio !
The second interior lighting group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination, LED illumination and incandescent lamps.
When the ignition switch is turned to the RUN position, the radio VF display turns ON at maximum brightness. When the park lamps are ON, all incandescent and LED back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch. At the same time all VF displays dim to match the indicated dimming level. The panel dimmer switch potentiometer is an input to the body control module (BCM). When the driver selects a dimming setting by moving the I/P dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. When the I/P dimmer switch is moved from MIN to MAX, all VF displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch.

'95 Lincoln town car. Husband was driving uphill and the digital dash suddenly went dark. Radio is working and a/c is not. Exterior light still working and so are interior lights besides the dash


Could be a bad wire possibly chaffing or grounding out to to another wire or frame. Check your fuses. You may want to pull the dash out and check that wiring as well

Could have connection issues at the BCM - body control module , lose ground . The BCM controls all the thing's your have problems with .
Turn Signal Lamps
When the turn signal switch is place in either the right or left turn position, the turn/hazard request circuit is pulled low, through a resistor. The body control module (BCM) uses the resistors to determine if the left or right turn signals have been requested. The BCM then supplies an ON-OFF voltage to the turn signal lamps and turn signal indicator on the selected side of the vehicle. The turn signals receive a ground at G101, G401, or G403.

When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) display (radio) turns on at maximum brightness. When the park lamps are ON all incandescent back lighting turn ON at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. When the headlamp switch is placed in the PARK position, the park lamp supply voltage circuit provides an input to the body control module (BCM). The BCM then supplies voltage to the instrument panel dimmer switch through the instrument panel dimming lamps control circuit. The setting of the instrument panel dimmer switch determines the amount of voltage that the instrument panel dimmer switch supplies to the BCM through the instrument panel dimming lamps low reference circuit. The BCM then sends a pulse width modulated (PWM) voltage to all the interior lamps. All the vacuum florescent (VF) and incandescent back lighting lamps are provided a specific voltage and are then grounded. When the headlight switch is turned to the PARK or HEADLAMP position, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.

Engine Coolant Indicator(s)
LOW COOLANT LEVEL
The IPC illuminates the low coolant warning indicator when any of the following occur:
• The BCM detects a low coolant level condition for at least 30 seconds. The IPC receives a class 2 message from the BCM requesting illumination.
• The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds .

The thing to do first would be to hook up a factory or professional type scan tool an check for Instrument cluster or BCM DTC'S - diagnostic trouble codes . Then checking connection 's at the BCM , testing power an grounds .

No interior lights come on when doors are opened. Very dim instrument panel lights.


theres probably a switch off to the left of the steering wheel (probably some sort of wheel looking switch for the brightness)

I own a 1999 Buick Regal GSE with 94K miles. I recently noticed that my dashboard lights sometimes come on, and sometimes don't. Sometimes, during the day, if my dashboard lights are on, and I pull out...


In the 99 Regal, the headlamp switch is also the dimmer switch for the instrument cluster.
With the headlights on, try rotating the switch to bring up the "nighttime" intensity.
If the headlight switch has a pre-set dimming function for the instrument cluster lighting (in other words, not adjustible by rotating the knob), then
replacement of the headlight switch would be the only way to fix the instrument cluster lighting problem.
See Wiring Schematic below.

Just bought a used 1995 Honda Prelude and the Tach and speedometer work along with the clock but I can't see any other gauges. (Gas, oil, temp and whatever else might be there. What is the problem?


Since you just bought the car, I thought that you might not be aware of the instrument lighting control. I apologize if you know this:
The dial on the dashboard to the left of the instrument panel controls the brightness of the instrument panel lights. Turn the dial to adjust the brightness.
To reduce glare at night, the fuel and temperature gauges dim when you turn on the parking lights or headlights. You then adjust their brightness when you adjust the instrument panel brightness. Turn the dial up as far as it will go to return the fuel and temperature gauges to their daytime brightness.
Hope it's that simple.

Back lights are dim on speedometer, odometer


You probably checked this, but sometimes we forget.
The dial on the dashboard to the left of the instrument panel controls the brightness of the instrument panel lights. Turn the dial to adjust the brightness. Also, to reduce glare at night, the fuel and temperature gauges dim when you turn on the parking lights or headlights. You then adjust their brightness when you adjust the instrument panel brightness.
Turn the dial up as far as it will go to return the fuel and temperature gauges to their daytime brightness.
I hope helps and it's that simple for you.

Instrument panel light not bright


On the drivers side ac/heating vent (to the left of the steering wheel on the dash) is a lighting wheel, this controls how bright your instrument panel is, move it all the way up
