SOURCE: tow/haul does not work on 2000 chevy truck. whereis fuse?

I had a problem with my tow/haul button not working. I came to find out that the gear shift had cut the wire running to the button in two. You may want to check that.

SOURCE: my chevy silverado 2000 tow haul wont work, light

check all your fuses. If your lucky you might find one the is blown and could be related If not fuse related then you need to remove the platic steering column cover. Under there at the end of the shift lever you will find two small wires that are for the tow haul button. These wires get brittle and break over time from shift level movement it seems. You will have to repair the broken wire and you should be good to go!

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

What would cause my TAHOE TOW/HAUL mode to engage on its own?


You need to have a diagnostic scan tool hooked up ,glitch in one of the control modules or a wire in the circuit shorting to ground ! probably something simple but hard to find ! With a factory scan tool they can check the input signal to the BCM ,PCM .
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, or cycling the ignition switch disables tow/haul mode and returns the transmission to a normal shift pattern.

Th e tow haul button is so if your towing a heavy trailer its easier on the tranny when you hit the button you generally dont need to use it for everyday regular driving.

I have a 2004 tahoe and this light came on i don't


That is the Tow/Haul indicator. Button on the end of shift selector was most likely depressed during shift or possibly a malfunction with the tow/haul mode selection system. (IE: Tow/Haul button)

I would put a scanner on the truck and see if new codes have been set and you should clear the old codes. The cpu runs a cycle of about 50 miles and then sometimes will reset itself if no codes are found.

My 2002 chevy silverado tow haul mode is now working. The light doesn't come on and the overdrive stays on


You either have a bad switch or the wires have lost contact.
The tow/haul switch is part of the shift lever and is not replaceable without changing the shift lever. The electrical connector is located inside the steering column covers. These wires have been known to part.

I have a 2000 chevy tahoe the tow/haul light does not come on and there seems to be no differnce in the shifting of the tranny


pfugi... I'm in the process of trying to change out my turn signal switch and that process requires pulling the plastic trim from on top and bottom of the steering column. I have the same problem that you do with the tow haul and after a few months of it not working I pretty much dismissed it as not a big deal, but I found the problem yesterday and I'd be willing to bet you have the same problem. Where the set of wires comes from the button on the end of your gear arm and into the steering column needs to have some flex to it as you shift the car and the extremely fine wire that they used simply snapped in half. There is absolutely no extra wire there and I'm deciding whether or not to solder on an extension or not while I have it open. I tow a camper and in Colorado quite a bit and I have just relented to manually shifting when necessary.

Tow haul light on sierra 2002 wont come on


I'v heard that the tilt wheel causes the wire to break. Most likely the wire has been broken. Somewhat easy fix.

Transmission tow/haul mode


Hi, the problem is when you are tilting the steering wheel all the way up it's putting to much tenstion on the wires that come outof your shifter that run to the tow/haul button. i am 99% sure your wires are disconected. rewire them and add some extra wire so next time there will be more slack in your wires.
