Just worked on my father's 2000 yesterday and figured out the only floor duct dumps all the heat in the passenger side floor board. I took a piece of 1.5" pvc pipe and notched it with the dremel tool, then took some HVAC Duct work metal tape and sealed the end of the pipe. I put the pipe so that it would duct out on the drivers side then taped it with the same tape up to the floor duct. once completed, I had about the same amount of air flow on both sides. He is happy now, his feet will stay warm.

sounds like it could be a mode door actuator problem which directs the flow of air in the heater case,

If you hear clicking, the actuator has most likely broken one of its teeth. A common problem. You need to track down the noisy actuator. Depending on the location and function of the actuator they can be relatively easy to replace or very expensive(labor $). The actuators are cheap compared to the expense to install, in some cases.
