I have a 2009 Yukon I just bought that has the 5.3L Flex Fuel engine and the 6 speed auto transmission. It has approx 200K miles. When I turn the ignition to on, the tow haul light does not light up on the RPM gauge when all the other indicator lights come on. Also, the tow haul switch does not appear to be doing anything. The +/- switch for when the transmission is in M do work, and change the indication on the gauge cluster.
I have not unplugged the orange cable coming down from the gear shift yet, but didn't want to go to deep until if I know if the Tow/Haul light on the RPM gauge should come on during the indicator light check on initial turn of the key to on.
Thanks in Advance
