Went to get the trailer for our trip this weekend, and it appears the tow/haul is not working. Worked OK last fall on our last trip. Pushing the button does nothing, and no indicators in the instrument panel light up. Is there a fuse somewhere for this? Anyone have any ideas? It's out of warranty. Thanks.

Probably have an open in the wire from the button through shift lever to plug near base of steering column. This has been a somewhat common occurance. You need to have a tech 2 and watch data as you press the button. I suspect the shift lever / button assembly. Pretty easy fix. Hope this helps.:D

Thanks to patrick for hooking me up to the tech 2 and pointing me in the right direction (and Wi Huck for letting him), to atschevytech in this thread, to Powder King and Machinator in the "Allison" thread, and Cobra #3747 in the "ask the techs" thread. You were all right; it is either the switch or wiring in the column. Off to the stealer to see how much he wants for the parts. Thanks again.
