Thanks,ghur said:Have recently had this on two different vehicles. It turns out only one blower motor was operating due to faulty fuse box relays. The evaporator was icing up I presume as it had insufficient air passing through it and A/C was cutting out. Relay swap fixed both.
Turn your blowers up high and set the control to face vent and simply check that air is coming out of both outlets. Make sure the vents are open.
