Before I pulled the backup fuse out (7.5), my air was working. Now it's not. When I turned the air on, the car idles up like the air is on but nothing comes out. Any idea what could have happened. Oh yea...I pulled the 7.5 fuse b/c the Check Engine light kept coming on. HELP! It's hot!

Put the fuse back in and then try to determine why the CEL is coming on. Pulling the fuse and then re-installing it resets the ECU so if the CEL came on then the problem went away the light would go out the next time you started the car. You need to short the service connector, turn on the ignition switch without starting the engine and then count the blinks to determine why it came on.
