ok i fixed the first problem with the ac if yall remember it would not change from the defrost setting. now it will not turn on the blower?? i checked all the fuses and relays they r all good. the one time i got it to work and stay working until the car was shut off was when i had it on and i unplugged the wires from the little white box on the passenger side to the left of the blower near the radio that thingie it worked. what is that and what does it control because something screwed up in it and its pissin me off cuz im in nc and its like 100 with a 97% humity so its hot as hell please any info would be appreciated
