You have to remove the entire cluster assembly to get to the bulbs, there is no other way, no room for this man's hand at the back.

SOURCE: 2004 Dodge Ram Pick up. The instrument lights for

The controls for fan speed, temp and air flow are contained in a self-contained control module attached to the center dash. To get to the lights, you have to remove the center dash unit (refer to the 1st diagram for removal).b5f7dfa.jpg Once the center dash is removed, turn it over and you will see three bulbs (you will actually see the base of the bulbs--refer to the 2nd attachment for illustration). d6d29c8.jpg
Simply remove the bulbs with a narrow blade, flat screwdriver. The Mopar Part Number for the bulbs is: 50138115AA. I paid about $2.25 for each bulb. Let me know if you need more info.

Check your tail light fuse, on the dodge ram the dash lights and tail lights use the same fuse so if the tail light fuse blows your dash lights will go out to alert you of no tail lights.

SOURCE: Need to replace instrument cluster/AC bulbs

Hello, You can obtain a 2004 Ram Factory Service Manual with all of that information available from The reason why it may be so important is because right before the removal instructions the service manual has diagnostic instructions to try. There are numerous pages on removing the instrument cluster, and cluster bezel.

(1) Disconnect and isolate the battery negative
cable. (For Airbag)

(2) Remove the cluster bezel from the instrument
panel. (Refer to 23 - BODY/INSTRUMENT PANEL/

(3) Remove the four screws that secure the instrument
cluster to the instrument panel structural support
(Fig. 5).

(4) Pull the instrument cluster rearward far
enough to access and disconnect the instrument
panel wire harness connectors for the cluster from
the connector receptacles on the back of the cluster

(5) Remove the instrument cluster from the instrument

Dash back cluster lights out only the cluster back lights all else works. on a 2006 chevy impala ss could it be in the body control module if so could it be reprogramed

Could be the instrument cluster .GM had instrument cluster problems for 2003 to 2006 . Wouldn't think BCM reprogramming to be an issue . Having a qualified repair shop or dealer check for DTC'S - diagnostic trouble codes an view data parmeters would be the first place to start .
When the ignition switch is turned to the RUN position, the instrument panel cluster (IPC), radio VF display, and the HVAC control assembly turns ON at maximum brightness. When the headlamp switch is in the PARK or HEADLAMP ON position, all incandescent and LED back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch. The dimmer switch is used to increase and decrease the brightness of the interior backlighting components. The BCM supplies a voltage reference through the I/P dimming voltage reference circuit to the interior lamp dimmer switch, which is part of the headlamp switch. When the dimmer switch is placed in a desired brightness position, reference voltage is applied through the dimmer switch rheostat and the I/P lamps dimmer switch signal circuit to the BCM. The BCM interprets this voltage signal, then applies a pulse width modulated (PWM) voltage through the I/P lamps supply voltage circuits and the LED dimming supply circuit to all related interior lamps, illuminating them to the desired level of brightness.

DTC B2652
Circuit/System Description
The BCM supplies a voltage reference through the instrument panel (I/P) dimming voltage reference circuit to the interior lamp dimmer switch, which is part of the headlamp switch. When the dimmer switch is placed in a desired position, reference voltage is applied through the dimmer switch rheostat and the I/P lamps dimmer switch signal circuit to the BCM. The BCM interprets this voltage signal, then applies a pulse width modulated (PWM) voltage through the instrument panel lamp supply voltage circuit illuminating the components listed below:
• Headlamp switch
• Instrument panel cluster (IPC)
• Driver and passenger window switches
• Driver and passenger door lock switches
• Outside rearview mirror switch

Circuit/System Testing
Ignition OFF, disconnect the (C2) harness connector at the BCM.
Verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
? If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the B+ circuit fuse is open, test the supply voltage circuits listed below for a short to ground.
• Instrument panel lamp supply voltage circuit terminal 3 C2
• Instrument panel lamp supply voltage circuit terminal 3 C6
Ignition OFF, disconnect all of the instrument panel lamp components fed by the BCM supply voltage circuits listed below.
• Instrument panel supply voltage circuit -terminal 3 C2
• Instrument panel supply voltage circuit -terminal 3 C6
Ignition ON, with a scan tool clear the DTC.
Operate the vehicle within the conditions for running the DTC and verify the DTC does not reset.
? If the DTC resets, test the instrument panel lamp supply voltage circuit for a short to ground. If the circuit test normal, replace the BCM.
Reconnect each component one at a time and verify that the DTC does not reset as current.
? If the DTC resets as current, test or replace the component responsible for setting the DTC.

How to replace brake switch on 2001 vette

Locate the brake on off switch, remove it and replace with a new one. Switch is usually located near the brake pedal under the instrument panel. Lay on your back and slide in under the steering wheel and look up and under the dash by the brake pedal, follow it up and the switch should be right there.

My instrument lights and headlights pulsate especially when driving

I would say no to reg or alt ,when you apply brakes there is dimming and that sounds like a negitive grounding problem not at battery,the dimming is caused from a back feed of ground possible.there are what are called body ground straps from battery to body panels and far as bat or alt advanced auto and most auto parts stores will be glad to check them out for FREE ,good luck

Hand brake lamp on instrument panel

The light is not only used to indicate that the parking brake is on, but also indicates that there is a problem with the braking system. Make sure your brake fluid is topped off.

What brake ststem do 2001 silverados have? rear brakes

Hi. Your 2001 Chevy Silverado is equipped with Antilock Brake System (ABS). You will identify also if your car is equipped with ABS by looking at the instrument panel for a yellow ABS indicator light after you turn on the ignition.

All the best!

    2. Disconnect the refrigerant lines from the evaporator. Plug the openings to prevent contamination.
    3. Disconnect the refrigerant lines from the accumulator. Plug the openings to prevent contamination.
    4. Remove the accumulator.

  5. Drain the cooling system into a clean container for reuse.
  6. Disconnect the heater hoses from the heater core tubes.
  7. Remove the PCM from the dash panel and move it aside. Do not disconnect the PCM harness connector.
  8. In the engine compartment, remove the heater/air conditioning housing assembly-to-chassis nuts.
  9. In the passenger-s compartment, remove the heater/air conditioning housing-to-dash panel nuts.
  10. Pull the heater/air conditioning housing assembly rearward far enough to clear the studs and air conditioning drain tube holes.
  11. Remove the heater/air conditioning housing assembly from the vehicle.
