Question about 2002 Chevrolet Avalanche

Open Question

The tow haul light on my 2002 Chevrolet Avalanche just started coming on at start up. It doesn't respond to the switch on the shifter knob, and goes off when the engine is killed. It may or may not come back on at start up. What is my problem?

Tow and haul button don't work how do i check it


More than likely the wires are broken at the base of the column shifter. If they are you need to replace the shifter. You can also extend those wires to a momentary switch and mount it in the dash somewhere.

Electrical issue


Does the vehicle start an run ? If it does ,the brain as you call it is working fine . The check engine light has nothing to do with the PCM /ECM sensing problems .You probably should take your vehicle to a qualified repair shop .

Tow-haul light comes on anytime it wants to and it switches between regular and haul by itself.

Tow haul light on sierra 2002 wont come on


I'v heard that the tilt wheel causes the wire to break. Most likely the wire has been broken. Somewhat easy fix.

02 gmc allison tran. wont go into tow-haul mode


THERE HAVE BEEN ALOT OF PLOBLEMS WITH THE SHIFTER HANDLE/SWITCH. THE BEST WAY TO VERIFY CONCERN IS USE A DIAG. SCANNER & VIEW TRANSMISSION DATA DISPLAY WHILE ENGINE RUNNING. THE SWITCH IN THE SHIFTER IS FAULTY. IF YOU SEE NO INPUT CHANGE WHILE DEPRESSING SWITCH THIS IS YOUR CONCERN.

Transmission tow/haul mode


Hi, the problem is when you are tilting the steering wheel all the way up it's putting to much tenstion on the wires that come outof your shifter that run to the tow/haul button. i am 99% sure your wires are disconected. rewire them and add some extra wire so next time there will be more slack in your wires.
