AC Symptom, Humidity Question

Recently I've noticed that AC is weak at idle and underperforming when it's really humid out....but much of the time blows really cold. But I just noticed that there's no condensation draining from the car. So I figure the evaporator drain or something is clogged.

My question: would a clogged evaporator drain be a sufficient explanation for weak AC at idle and and generally underperforming AC with very high humidity?

Just had it recently recharged....it's R134a, if that matters.

Thanks!

Probably a correct diagnosis. You will need a high tech tool for this job. In the country we fashion this high tech tool from baling wire. For city people, an old coat hanger makes a suitable substitute.

Approximately where is the bottom of the drain on the 124? I don't have ramps, so I'm wondering if I can access it.
