My blower motor will sometimes not run automatically unless I press the Defrost button and then put it back to whatever mode I want. Pressing the Defrost button will always bring it to life and then it will work automatically in any other mode.
The other thing I noticed is that pressing the high or low speed button will also not work until I cycle the system with the defrost button.
