Also on pages 433 and 434, there is something different about the blower assembly. It says auto climate. I wonder if the blower assembly needs to be swapped as well?

I'd pay $150 for the module. That seems pretty reasonable.

Just a guess on the blower motor; most manual systems have 4-5 speeds via a register or electronic controller, and most auto systems have either infinite speed control, or a few more speeds to make the variations in fan speed less noticeable. Have never looked at Tundra schematics, but the new Sequoia which has auto temp control has 9 speeds for the front HVAC cabin fan according to the info posted in the now current post discussing the aux condenser fan.
