Ok here is my situation, Last summer when I turned my a/c on it blew very cold with alot of pressure, I used it on 3/4 fan speed and it would freeze my hands when drove, now lately when i turn it on it is cold but I have almost no blowing power when i turn the ac on, but if i turn on the bi-level it blows very hard. Why would it do this? Is my air intake clogged or is it the air damper?

When you have it on bi-level, it blows harder through the vents than when on regular A/C setting? Or are you saying it blows good at the floor, but still lame out the vents?

Ya it blows great out of the front vents on bi-level but it sucks when the ac is on.

There is a good chance that your evap core is partiallay clogged with mildew that is restricting flow.

Where is the evaporation core located in the car? How do I get to it?
