I noticed this morning no heat unless I set the temp to Hi. Hi on drivers sent hot air, same on passengers side, set one side below hi and that side goes cold. I also noticed the other day the drivers carpet was wet. Since we had some rain recently I figured the sunroof drains. I ran a steel rope down it but didn't see anything drain from the car. Also I tried, but couldn't push up through the floor drain under the drivers seat. Both hoses to the bypass vale were hot. Antifreeze was full, but I did add a pint or less to top it off yesterday. HVAC reset showed no error code. I replaced the air handler 2 years ago so I am hoping that's not it. I also replaced the radiator 2 years ago. What should I look at next? Thanks.

2002 9-5 arc v6 92000 miles.
