front ac will come on/off, one moment the air is blowing out the next it stops on 2002 Chrysler Town & Country

2002 T/C minivan while driving the AC will stop blowing out the vents, then after awhile it will start blowing. Sometimes it seems like it don't blow out as hard as it should. The air is cold when it works, the back AC unit works fine. Replaced module behind glove box recently, to correct the issue of working only on high speed.
