stock airfilter box is integated with the AFM/MAF sensor... that is a 4 or 5 pin connector.
you'll maybe need to take a pic of that 15 pin connector and post it - let's see.
For now, since you say, there's no airfilter box,.... i will assume the AFM is also missing. And you can never achieve a smooth engine performance without the AFM.
a/c wont even blow exept in defrost mode.<<< could be a problem in the circuit board, stuck or inoperative linkages that move the blend doors to open and close.
Q: do you get cold air coming out of the defrost vents?
