I just got through changing the filter just to see. Nothing changed. I was using an AC Delco filter, but the one I went and got last night was the Valucraft filter that Autozone carries since it was the cheapest. It's only for testing purposes, though. I will put the AC back on tonight or tomorrow since changing the filter didn't help any.

What's left, now?? Drop the pan and check if the pump screen is clogged? I did notice when I removed the first filter, that there were some tiny bubbles floating at the top of it (I had to pull the car into the garage). Any indication as to a specific problem?
