Hiya,
I have an 02 Silverado 1500 4x4 with a 5.3. I believe it's an 3/4 ton (has the suicide doors).
Seems my Tow/Haul switch has decided to turn off and on at will. I can press the button on the shifter and it does nothing to turn it off (or on for that matter).
Sometimes, shutting off the engine will get it to go off and then, when you take it out of park, it goes right back on.
Other times when it comes on while driving, stopping completely then gunning it through the first three gears will get it off.
Other times still, it will come on and go off on it's own without me fiddling with anything.
It's been suggested to replace the shifter. But the guy says there is no guarantee that it's what is causing this issue.
Any thoughts?
Cheers!
Outlaw <3
