Customer Question

I have a 2009 Freightliner Columbia 120 Day Cab, Detroit Engine, VIN: 1FUJA6CK38LAC4537
Driver turns HVAC blower to low. After some time, and on random days, it will go to high on it's own. Driver restarts truck to reset it. About 4 weeks ago this was happening and so I replaced the blower motor because the resistor is integrated. Now it is happening again.
We are getting the following code:
MID 146 SID 10 FMI 12
Cab Climate Control
Blower Motor
Bad intelligent device or component
