Tow/haul switch

Tow/haul switch

Postby nvbbqman [OP] » May 04 2012, 3:11am

I have a 02 1500 Silverado with 230K and the t/w is engaging on its own while driving and the only way to turn it off is to shut off the motor. Is there a way to disable it all together?

I'm not sure if you can disable it or not, however, the small wires running from the switch and through the column tend to break after extended time in service. I would check them to see if they may be shorting to ground or otherwise damaged.

You have to take the steering column cover off and look for them where they run into the shifter lever.

Do a search on the forum, I believe I have seen some posts regarding this repair.

I believe it is all snap together. You have to pry it apart where u see the seam. It almost feels like it's gonna break if I remember right cuz I had to fix mine in my 05 about 2 yrs ago. It's also a s.o.b. to get back together but it will go with some patience.

There should be some torx screws on the bottom of the cover that you have to remove first.

Sorry, I was assuming you meant how to get the switch out, not how to get the cover off. My bad.

Tow/haul switch

Postby Mikez94 » May 11 2012, 5:18am

Just did this a few weeks ago. Take off the screws on the underside of the steering column. Then you pull the tilt wheel handle right off. Its hard, bit it comes off. Then you pull the steering column apart. There is a screw in the shift lever(to access that you need to pull the rubber back on the lever) then you follow the bright orange two wore to the harness right under the steering column and unplug it. This is definitely the problem for you. I went to the dealership and picked up the part for $70 because my friend works there. (normally $100)
