    Hey there, just wanted to say hello to everyone and introduce myself. I just bought a 2001 Silverado Ext. cab short box 2wd 4.8 Liter. This is my first 2wd truck ever, I have owned a few 4x4 and several Suburbans. So the problem I have is the tow/haul mode does not seem to engage. Is there a solenoid or something that may have went bad, or something else. (No light comes on, on the dash, and the trans shifts the same).

    The govy I drive for work has the button but no light comes on either. I don't think that the two wheel drives have that option on them.

    What Most likely Happen is that the Wire that runs down the Shifter and where it meets the Steering Column, down at the Base, has over-time has got Pinched and finally Broke.

    You wont notice the difference in shifts really, but the little pic on the shifter should light up, most likely the wire or sensors on the button have worn out.

    Welcome to the site! I agree with Jason (vncj96), it is hard to tell if it works but the light on the shifter should come on.

    Tow/Haul

    Hello, I have a 2001 GMC 1500 Sierra 4x4 that the tow/haul stopped working, went to my local GM dealer and will cost 85.00 through work for a new shift lever to hopefully fix the problem, been told here and at the GM dealer that you can't just replace the switch at the end of the swifter. Dan

    Went I Engage the Tow/Haul Mode in my Truck, it will Light up & show Tow/Haul, at the Top Right Hand corner of the Dash.

    Thanks for all the input. I will have to check and see if the 2wd even has Tow/Haul mode. I will post some pictures of my truck soon. Thanks again.

    I have a 2001 Sierra that has the tow/haul button and it is two wheel drive. I love the feature but recently mine stopped working as well. I am willing to bet it is the wire breakage issue. I havnt looked into it at all. This was my first google search item. Thanks for the pictures of the wiring harness. New to this site as well. Do a search on 1radgmc for pics.

    Welcome to the site! Go to the Q and A thread for more answers. Yes 2WD have the tow/haul options and sounds like the problem is in the shifter.
