Heater problem
1999 Honda Accord 4 cyl Two Wheel Drive Automatic 120k miles

Recently my heater/AC makes a loud rattling/vibrating noise when on, and this sound gets worse the higher the fan speed. It sounds like it's mostly centralized to the passenger side of the car, and as far as I can tell temperature has no effect. What might be causing this and what can I do?
