A/C not working HELP
Wednesday - my car was blowing nice cold air and the A/C system was working flawlessly.
Thursday - the A/C begin to go in & out blowing warm air and then finally thursday evening, the a/c won't even come on and no air blows at all. what could be the problem?
the AC led does remain illuminated when i turn on the AC, but no air comes out any of the vents

Since you haven't ruled anything out, the problem could be anywhere in the A/C system. First place would be to look under the hood with the A/C on and engine running to make sure the compressor is running.
Look for signs of oil around the A/C lines; that could show a leak.
Need more info to help dial it in.
Have a good one,
Mike

If no air blows at all, you have a vacuum leak. Vacuum controls the HVAC doors.
I certainly hope you have an AGM battery ? If not, remove your battery and check for any leakage. Leaking batteries eat through the vacuum lines located under the battery.
You did not replace your oil pressure sensor recently, did you? If the small hose at rear of manifold is not on good, you can have problems when it slips off.
