2004 Optima issues

I have a 2004 U.S. Optima 4 cylinder with manual tranny at just over 60,000 miles. Two weeks ago it started exhibiting strange behaviors right after I returned from a trip where I allowed my teenage daughter to drive it for a week while I was gone (she is a very careful driver - I doubt she did anything to cause this).

1. The radiator fan starts almost immediately after I start the car - within

10 seconds. I hadn't noticed this before, and I would assume it should not turn on until the engine is warmed up.

1. The heater fan blows air through the vents, but generally - but not always - airflow drops to almost nothing after a few minutes. The fan continues to blow, and if I adjust fan speed from 1 through 4 I hear sounds of the fan's rpms increasing but almost no difference in airflow through the vents - there is virtually no airflow through the vents at all at any fan speed. It's almost as if something is blocking the vents.

2. When #2 occurs I can feel warm air through the vents but as described above it's just a trickle - and it doesn't change when I change fan speed. I have noticed that if I stop the car, turn it off, then turn it back on then normal heater/fan operation resumes, but it will malfunction again shortly.

1. When I am accelerating, and push in the clutch to shift from 2nd to 3rd,

3rd to 4th or 4th to 5th, the engine continues to rev even if I pull off the accelerator prior to pushing in the clutch. The engine will rev up around 200rpm or so, then subside. Shifting from 1st to 2nd, I haven't noticed this. I have also noticed that when I pull up to a stop light, the engine will idle around 1,100-1,200 rpm but gradually drop to 800 where it has always been.

1. I notice a whine from under the hood that increases as the engine's rpms increase. As I shift from gear to gear the whine decreases with the decrease in engine rpms, then increases again as rpms go back up in the new gear. When I shut off the car the whine gradually decreases to silence, almost like a turbine spinning down. It's not very loud, but it is noticeable and I can't remember it being there before.

My odo is at 62,000 miles now. Does Kia cut off warranty right at 60K, or will they likely cover this as I am right at the mark?

The car is due for its 60K service, but these symptoms don't seem like they should be related to plugs, wires, timing or other belts - right?

Any ideas or suggestions?

TIA,
