hi, I thought maybe I was low on freon but had it checked and it was okay and pressures were okay, however only warm air comes out of vents. at first it was warm on drivers side and was blowing cool on passenger side. now both blow warm. any help would be appreciated. :?

What is your cars trim level, do you have automatic or manual controls?

it has auto climate controls for driver and passenger

You may have a damper that is not shifting. Try manually changing ventilation modes and check air flow at appropriate outlets. When you select windshield defog function, is air conditioned air coming out of defrost vents at base of windshield? Just trying to shoot ideas out here.

thank you , I will try those ideas today.
