No Interior Ventilation

[mackguyver]

I have searched and searched this forum and the Internet but can't seem to find anyone else with my issue. Last week, I got in the car and the A/C came on full blast, but no air came out of the vents.  I turned it off and then back on a few minutes later and it worked.  It kept working the next several days and then it did it again.

Now it has died completely.  When I turn the fan speed to max, a tiny bit of cool air comes out, but I can barely feel it.  The 2 A/C & Heat fuses are fine and there are no codes in the CEL.  I have the classic foam in the duct issue and worry that it's clogged the fan, but I can't hear the fan starting at all, but I do hear the A/C turn on and some other electronic/mechanical noises when I turn the fan on or off with the controls.

Does anyone have any idea what might be wrong?  As a Floridian with 90+ degree days, your help is much appreciated!

Sounds like the blower fan motor or the power transistor is gone. If there are any error codes on the climate control unit, it will not show up as CEL. You need Durametric or alike to query the climate control computer for error codes.

Without scannng it, you can check the fuses, unplug the motor and hotwire it to see if it spins.

Ahsai, thanks so much for your reply and I'll take a look at the blower fan motor and transistor later today.  I might have to pick up a Durametric as well - it seems like something I should have now that my car is getting older.
