I had an issue with a small red squirrel taking up residence in my HVAC blower fan. It caused the blower fan resistor to go out. I replaced the blower fan and the blower fan resistor. All was well for a little while - but nowthe flow from all the vents is very minimal. The temp control seems to provide hot/cold as expected. And the blower fan is being controlled correctly. You can hear it trying to push air on full blast - but something is obtructing. I also did the HVAC controller reset procedure which went through the steps as expected, but minimal flow from vents when the fan is on high. Maybe some of the rodent nesting is blocking the vent tubing somewhere - I did remove a fair bit of debris from the blower fan area. Or maybe the blend door actuator is not working? Any ideas of how to procede would be appreciated.
