Most likely one of the wires has broken where they twist due to the steering wheel moving. The easiest way is to bypass the normal button and put a momentary button somewhere else. The voltage/amps are low so doesn’t need to be a hefty switch.
I just got a 2013 extended cab 1500 4X4 5.3 with heavy duty front and rear suspension that is used mostly as a weekend toy. I noticed that the ride is a bit harsher than my old 2003 5.3 Z71 off road extended cab This week I needed a rental for a 400 mile trip and was offered a 2018 4X4 1500 crew cab when I told them I wanted a big comfortable vehicle. I have to admit that it is great on the highway and if find myself pushing 90 MPH before I know it. Is the ride difference due to the year, suspension, or maybe tires? The air pressures in each vehicle is about 32 cold and 35 when heated up.
I just got the Range AFM disabler for my 2013 5.3 4X4 with 125 K on the clock. It is mostly a weekend toy that is seldom used during the week. I was surprised to see an important note telling me that I should not leave the Range installed if I don’t drive it daily because there may be a draw on the battery in some vehicles. Is there way (other than seeing if the battery dies) to find out if I need to remove the Range from my truck during the days it isn’t being used?
It is highly unlikely someone cut the wires in the steering column. Almost every Chevy truck with the tow package ultimately has the thin wires break. Most people don’t reattach them because they will break again. They just add another MC push button switch to the dashboard. i have done it to 3 trucks and have a switch ready for the current one
Just like MaverickZ7 - I USED to be a GM fan but these AFM issues have turned me away. The guy that suggested it is not a common issue has to have a screw loose (or maybe works at a Chevy dealer) because horror stories of the AFM issue is all over the web on many GM forums. The body of my truck is in very good condition so I am beginning to save money for either an AFM delete package or a new crate motor (if needed). Looks like GM made the same type of decision the Ford did on the Pinto gas tank, but at least people are not being roasted do to their decision.
When your neighbor gets laid off it is a recession. When you get laid off it is a depression. When my friend's truck fails because of the AFM it is an issue. When my truck fails because of the AFM it is a disaster. When it hasn't happened to you it doesn't exist. When it happens to you it is real.
It looks as if I should have done a bit more homework before getting another Chevy. It is now decision time - Keep it as is, change the oil every few thousand miles and hope. Keep it and completely swap out the AFM system now. Keep it and get a 5.3 crate motor if things break. Dump it and get a Ford. - I once had a Ram. It ate transmissions every 40,000 miles and the body fell apart around a great motor so it is not a consideration.
These are your best friends!
