Next time on the road while the system is on and cooling report back what the temperatures out of the drivers side and passenger side vents feel like . I'm talking about the vents by the radio. Is one warmer/cooler than the other? Which, if so?
By the way , what level trim ? CE , LE, XLE?

Usually being low on freon causes this. Add a couple ounces to the system and you shoud be good to go.

The 2nd gen LE does not have individual temp controls for the right and left sides.

AFAIK , you are right. I asked in post number 8 what the trim level was and I dont believe I got an answer.
