I would yank the high pressure fan switch (little side pipe off the high side expansion pipe) from the j-yard too. those things don't go bad too often.

I'm thinking that there is a problem that the system isn't cycling properly, hence the ice. Either that, or the pressure switch is really bad. You should see the accumulator sweat during hot weather, but you shouldn't see it icing unless there is a very low charge level and the pressure switch is bypassed... since pressure is directly related to evaporator pressure.

Also, yank the relay for the condenser fan from the junkyard. The relay rides along on the ignition coil bracket right near the ABS unit (if equipped) and the left side strut tower. Black relay.

Something about your system doesn't add up. Either the icing, or something. I'd get a set of gauges on it, especially in this case, a low side gauge (wal-mart if you don't have high/low pressure gauges available) to find out what the problem is. it sounds as if the low side is waaay too low.
