When you notice your car no longer blows cold air from the air conditioner, you know something is wrong. The cause of the problem may be simple to diagnose and fix or it may be a serious issue. Take a shot at troubleshooting the problem yourself, and you may save yourself much time in money.
Lift the hood of the car with the engine off and first look for visual clues as to what the problem may be. Look at the compressor. It is cylindrical in shape, sits directly next to the engine and has a belt. Make sure the belt is intact and there is no rust.
Start the engine of the car and allow it to run while looking at the compressor. Look for obvious signs of malfunction. Touch both of the hoses attached to the compressor. The larger one should be cool, and the smaller hose should be warm but not painfully hot.
Listen for the blower motor to make sure that it is running, but not overly loud. Step into the car and play with the air controls on the dashboard to make sure the blower motor is making the appropriate increases and decreases in volume.
Change the fuse if the controls are not working. The fuse box in a Chevy Corvette is on the floor board. Lift the carpet on the passenger side, and then remove the toe-board covering. Pull at the top corners of the panel to gain access to the fuse box. In a corvette, it is fuse number 28 and can be replaced with one of the spares available.
