Default Climate Control Problem

Hi all - Long time reader, first time posting.

I have a 2000 Bonneville SE, 140,000 miles. Dual Zone auto climate control. At this time the passenger side works perfectly, but on the driver side the heat is weak in the winter, and the a/c is weak in the summer. After reading some, I figured it was the driver side air mix door actuator, but that doesnt seem to be the case. The motor turns properly when I adjust the temp, and I even removed it and with the door open all the way (manually turning the shaft), the air out the driver vents is still not nearly as cold as the passenger side. The air mix works ok and changes the air flow (hot vs cold), but the air flow before the mix door seems to be the issue.

Does anyone have any ideas of where to look next? It would be very helpful if anyone had a diagram of the driver side system....

Added some refridgerant and the driver side cooled down, not as cold as the passenger, but it worked.
