tow haul not working

[abby1]

hi all

I'm just bought a 2004 dmax and the tow haul doesn"t work so I checked all
fuses then pulled the colum apart to check in there if I unplug the 2 pin
conecter to the tow haul button and test the harness back to the chassis
there is power and ground is this right I know it doesn"t seam right to me
that there is power and ground in a 2 wire harness going to a switch


any thoughts thanks

What symptoms or indications make you say that it is not working? Are you not seeing engagement upon demand for towing or decelleration upon the need?

no light on dash and when driving there is no diffrence in aceleration or
deceleration when driving I've been told I should see a big diffrence compared to my gas truck specialy on decent of a hill when let off on the petal

No action untill you hit the brake on decelleration.

button in the end of shifter not working I put some contact cleaner in there and now it works sometimes if you really play with it

thanks

Same thing happened to me. I had to buy a new shifter. I believe the button on the end of the shifter went south.

Hope this helps

well finally found the problem removed the shifter and the wire behind the plastic wire holder was broken resolder and works great

Thanks Abby
