A/C Roars & Stops Blowing Air

[Joel4PW]

After ~ 30 minutes or so of driving ('98 V6 Firebird), my A/C starts to roar and stops blowing out air. I can't feel air coming out of any vents. Cutting the A/C off/on a few times sometimes gets it to work; cutting the car off/on also sometimes works. Any tips?

Re: A/C Roars & Stops Blowing Air

If it's roaring it may be that your blower is running, but something may be blocking the ducts so no air gets through. Can you tell if the blower is working? Check the defrost vent and the floor ducts to see if air is coming out of those.
