2006 Chevy express 2500 instrument panel lights stopped working after two wires touched going to tow switch. No blown fuses


Which I/P lights ? Instrument cluster , radio , HVAC control panel etc.... All the I/P light's are controlled by the BCM - body control module . Do you know about electronic control modules ?
DTC B2610 Passenger Compartment Dimming 1 Circuit
The body control module (BCM) receives a variable voltage signal from the instrument panel (I/P) dimmer switch requesting to illuminate the instrument panel controls illumination lamps to a desired intensity. When this occurs, the BCM directly sends a variable voltage based on the I/P dimmer switch position on the backlight lamps control circuit, instrument panel lamps dimming control circuit, and the LED dimming signal circuit.
Voltage for the backlight lamps control circuit, instrument panel lamps dimming control circuit, and the LED dimming signal circuits is from the TBC 3 fuse 16 in the underhood fuse block directly through the BCM to these circuits.

• Perform a visual inspection for loose or poor connections at all related components. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
• A short to ground in the following circuits will cause the TBC 3 fuse to open:
- The backlight lamps control
- The instrument panel lamps dimming control
- The LED dimming signal
- Battery positive voltage from the underhood fuse block TBC 3 fuse
• An open in the TBC 3 fuse will cause the BCM to set the following DTC:
- B0951
- B2610
- B2625

DTC B2615 Passenger Compartment Dimming 2 Circuit
DTC B2620 Display Dimming Pulse Width Modulation (PWM) Input Circuit
DTC B2625 Display Dimming Pulse Width Modulation (PWM) Output Circuit
Do you know how to Test for a high resistance, an open, a short to ground, or a short to voltage in the following circuits. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
• 5-volt reference
• The dimming input
• The dimming return

Tow/Haul mode enables the operator to achieve enhanced shift performance when towing or hauling a load. When tow/haul mode is selected, the tow/haul switch input signal to the body control module (BCM) is momentarily toggled to zero volts. This signals the powertrain control module (PCM) or transmission control module (TCM) to extend the length of time between upshifts and increase transmission line pressure. Cycling the tow/haul switch again disables tow/haul mode and returns the transmission to a normal shift pattern.

After reading all the pertinent info. to your problem, doing testing ,Checking for DTC'S -diagnostic trouble codes in the BCM , checking power and ground's for the BCM an checking voltage at the tow / haul switch to and from the BCM .is where i would start . Do you know how to do electrical testing ? Read a wire diagram ? If not there are videos on youtube for learning how to do basic automotive electrical testing , how to read wiring diagrams etc... You can find free wiring diagrams at
http://www.bbbind.com/free_tsb.html The only thing with this is you don't have info. saying where componet location's are . This is were factory service info would be helpful

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.

Drl module


This might not be much of an answer,, But why do you think your DRL is ,gone,,, Do you have HIDS? led tail lights or after market bulbs anywhere in you running lights system, such as turn signals front or rear marker lights corner lights etc, if you do have Hids or leds,, and you didn't put in resistors in line with the lower wattage led bulbs you car can throw the drl light, like turn it on., and with daytime running lights you will short out the hids, since they are not meant to run at say 4 volts like the factory non hid ones that are dim when the running lights are on.... I don't know if my answer will help you but I hope it does.. good luck

Headlights only work on bright


i had this happen with my dodge ram 1500. the guy i bought it from put 350 dollar moon lit lights in with leds and they looked impressive but the issue was that they didnt go bright and i could only see 40 feet in front of me and i was sure taping led flashlights would have done me more good that those stupid headlights. then i had the idea of if the brights work and the dims dont then that means no electricity is getting to the dims so i decided to bridge the power from the bright headlight to the dims and it made all four work. now they all work, and only on bright. so im figuring there is a issue with the wiring in the truck. so this is a temporary solution if you really need just plain old lights like i did because i live out in the country

The head up display is set for maximum power but is very dim. Are these LED's - does the entire module have to be replaced? If I switch to metric display over 62mph for a 3-digit kilometer display, the...


The mph is led and can be replaced, but you have to get it at a salvage yard. As for as the back lighting for the cluster it is bulbs. If these are dim then you should replace the dimmer switch

Click on the link.
The top wires to headlamp are voltage for hi or lo beam.
The bottom black wire is ground. You can use a test light to check voltage and ground.
