if it freezes up it has a restriction usually, expansion Valve ,the thing that is doing it ,but need to put some gages on it and see if the low side is going under vacuum since the low side in the suction side and it its vacuum ,but when the Guage's are hooked up on the high side and the low side ( suction & discharge ports) with the A/C on Max Fan on high the low side will stabilize at about 29.9 inches of mercery or 30 to32 inchecs of vacuum, if it starts going lower and the more rpm's added and the hight side climbs dangerously higher than 250 275 300 the high side line can and will explode, so if this is happening you definitely have a restriction, depending on what system r-12 or r-134-and this don't matters the type of vehicle does it have a orifice tube or expansantion valve they both do the same thing ,and usually this is what is wrong providing its full of freon and fan and all else is ok, this is most likely the place to look ok
