Trail/Tow indicator light

[last-442]

First off thanks for all that replied to my previous thread regarding the cabin air filters for the '03 Yukon.

The question I have is this, my 03 Yukon with 35K on it has the trailer button on the gear selector. When I press the button, the indicator on the dash does not light up. Is this common? The manual states that if it is selected, the mileage worsens, how do I know if it is engaged or not?

Thanks

there has been a few times when i start up my 2001 when it has an issue starting and then the tow/haul light comes on. i never really worried about and it hasnt happened for some time. not sure why it did it but like i said it hasnt done it in about 2 months.

I just strange that it stopped working. The light use to come on, no biggie, not a lot of towing being done with it. I don't think I want all the hassle that comes along with changing the bulb in the instrument cluster. I'll live with it off.

I just got the Tow/Haul indicator light issue resolved. Turns out that the wire in the shifter handle broke/frayed what-ever. The dealer's service center repaired it, instead of replacing the entire shifter handle for a cost of $425 plus labor.

I believe it resets itself anyway every time you start the vehicle. That doesn't help if you were trying to turn the Tow/Haul mode on, but it shouldn't be an issue if you didn't want it on.

shift points

The easiest indication that tow/haul mode has been engaged is the difference in the shift points of the transmission. In an unladen truck, the revs for each gear are noticably higher prior to a shift, and the engagement is harder; you'll hear and feel the difference. That's because the PCM changes the engine mapping to compensate for the increased weight expected when towing/hauling loads.
