Default a/c not blowing out hard enough--93 SSEI

My a/c is ice cold, but does not blow out hard enough. I can hear the blower motor changing speeds as I select from low to high and back. But the flow of air does not get any faster at high fan speed. Air flow is the same no matter what fan speed is set on. Can somebody help me?

Check to see where the air is blowing out.

Dash vents
Defroster vents
Floor vents

I'd risk a guess it'* coming out more than one place and being that you have a 93 you won't have a choice of where it does.

air is coming out wherever i choose it to come out at, whether it be the dash, floor, or defrost. It just does not blow any harder when i speed up the fan. everything is working properly...the air just always seems to blow at a low fan speed even when the fan is up on high. i can even hear the blower motor increase but the air flow does not.

Sounds like you have a bad blower moter resister. They are inexpensive but hard to find.

I disagree. I believe you have a plugged or clogged evap core.

I gaurantee your airflow will improve. This may or may not be the problem, but is very likely, and will at least be part of the problem. Be very careful on the rinse cycle if you don't want water in the passenger footwell. I suggest having a wet/dry shopvac handy. Trust me.

Hey Bill....do our boxes also fill up with debris like others? I know on some cars you can get a box full of leaves, pine needles etc if you park under trees.

It can, but not bad usually. And the clogging can't be seen, it'* best to just clean it once you have access. You can't see alot in there.
