Power locks and air wont blow out of the front vents

Okay, I was trying to figure out how to fix the air from blowing only out from defrost cause it stopped coming out the vents by taking the fuses and relays out and putting them back in. I also took the battery cable off to reset the module but nothing fixed and now the power door locks have failed completely. Even if if I try to use the key button alarm and nothing. So I am having to lock them manually. Can you please tell me whats going on?
