Glad you got it figured out. I am guessing that there's some sort of "safety" feature to ensure that without the ability to cool with the fan (a necessity in TX), the truck bypasses the starter. Now in MT, I don't think the fan clutch ever engaged in my Excursion...at -55 below and the fact it was already a cold blooded beast, I am betting the fan got rare usage. Now my 6.4L on a 104 degree day with the A/C on, climbing hills you can hear the roar of the fan come on. My 6.0L always pitched a fan clutch code yet it worked as it should. Was fixing to tear into it and replace the peeling grille at the same time and on the way home to order the grille the truck was totaled when a man ran a stop sign.

As already said, thanks for updating this. I know for me, the fan clutch is not something I would have considered especially with the tow/haul light flashing. Usually that means there is/are DTC(s) stored for the transmission.

Just out of curiosity, did you ever try to have it read to see if any codes were present?
