Yes, in can be a condenser with debris on the facing forward side, system cannot get rid of the heat that was collected from the interior. Builds up a higher pressure (read temperature) and the high-pressure switch cuts out a working clutch. But I also HAD 1 in all the years I worked on cars, the moisture from the interior collects on the evaporator, due to the Drip hole plugged, and ice forms on the evaporator so blower motor air will not flow through the evap's radiator type core. It just blows the warm interior air back into the cabin. Most of this type of problem though is found by a puddle on the floor of the cab, ice melts when vehicle parks. Does it have a cabin air filter?? this could be plugged (no air flow) or yours did not come with one (you can add it yourself)- I did on mine. But this usually cause a system that only gets cool not cold. If you are not sure of how a A/C system works, lots of bits of info to read to help you understand the system. Here is a very short explanation that may/may not confuse you. In a classroom much easier to explain. 1) most things are three things when heat is applied: solid, liquid, and gas (ice to water to steam). those 3 states happen to everything at different temps. The freon used in A/C is chosen as it never freezes (solid) in a auto. Everything on this planet like to be warm (the way I explain it - may be technically wrong - think black bear vs polar bear. In an A/C system it's pressure (why gauges are used to test it) low pressure it is acold liquid to high pressure a hot gas. Ready?? here goes -again trying to make a short explanation of a complicated system- In the dashboard (EVAP) it's a cold liquid (low pressure 25-32 psi) Caused by a restriction inside the tubing (orifice tube) which is between under hood area and dash. It wants to be warmer than it is, so it accepts the interiors heat. As an ice cube as it gets warm goes from liquid to a gas/liquid, passes through a few items to become all gas, because (liquid cannot be compressed!) the gas goes into the compressor and is squeezed High pressure on the gauges. Now it is at 400PSI, 300-400 degrees. Now the outside air maybe 100+ degrees BUT that air is cooler than the 400-degree freon inside the system. So, the air going thru the condenser, accept that heat. and round and round it goes. That might help give you the general jist? So, anything anywhere that "blocks" freon or air flow will screw it up, not enough freon in a system, it turns to a gas before it can accept all the heat from an interior. I used to teach also, but hard to do it here.
