Is there an actuator door or something that could be bad? Or could it be my blower? It isn't as strong as it used to be.
Also, it won't blow on my feet or on front glass (defrost) at all. That's what makes me think it's some sort of actuator.

 

Also, had coolant pressure checked this morning and it checked out ok.

 

it's all done with cables and levers the only actuator door on the fresh air and recirculate switch, could be your fan going bad, might have to replace your cabin filter is there is one

 

All good suggestions...cabin filter is an easy check and fix and probably worthy of being changed (if there's one in there) anyway.

Not being able to blow on your feet or on the windshield for defrost leads me to believe it might be a 'blend' door issue.
