05 sub. tow haul not working

I have a 2005 sub. and the tow haul does not work i could not find a fuse for it or any info in the owners manual any one have any info that would help?

hello there. i would start by getting a wiring schematic or a flow chart off a source such as alldata mitchell on demand or gm SI. this should point you in the right direction. is this the only thing not working?

yes that is the only thing not working.Thanks for the sugestion i will do that and see if i can figure it out.:wink:

i used the alldatta site and figuered out the wiring and where to look,and when i took the cover off the steering collum i found a broken wire coming from the shift lever so i spliced it and it worked.
Thanks again for the info.:smokin: :rofl: :loser:
