I had my blower motor fixed. Well now the fan is stuck on high and it doesn't blow cold or hot air it blows what feels like outside air.

The trouble codes need to be retrieved from the HVAC module, this will give us a direction to go because this system is pulse width modulated in relation to blower motor speed.
