I have a 2014 GMC Sierra 1500 and recently the air on the drivers side has not been as cool as the passengers side. I’m assuming that is the blend door actuator but I’ve also noticed that on high the amount of air blowing is more like low to medium out of all vents. Is this probably a faulty blower motor?

I replaced the coolant temperature sensor with an AC Delco sensor and the thermostat but the temp is still remaining on 160 and the electric fan is programming up to high and staying on. Is there a reset that I’m missing?
