Your system runs the A/C in the defrost mode to remove moisture from the air being directed on the windshield. It is operating as advertised. Your owners manual should define the function.

2004 Chevrolet Cavalier gets hot while using defroster?
The defroster turns the AC compressor on so if the vehicle runs hot with the AC on it will also do so with the defroster. To fix this look first to see if your Ac fan motor is working. On this year model I believe there are two different cooling fans, 1 for the motor and the 2nd for the air conditioner. A lot of times it may just be a fuse or maybe even a relay. Anyhow, start there.
Is it normal for a central air conditioner to be making a loud buzzing noise off-and-on from outside?
it depends on how loud it really is, because unless it's unusually loud then yes it's normal. All that is, is you compressor cycling on and off to your temperature setting. When the temperature goes above the setting it turns on so it doesn't get too hot. When the temp falls below the compressor will shut off so it don't get too coldAnswerit depends on how loud it really is, because unless it's unusually loud then yes it's normal.

Why is fan loud when air or heat is on?
The electric fans used to cool the engine are designed to switch on to full speed when the air conditioner compressor is being used. When you turn on the heater/defroster the air conditioning compressor also turns on to help remove moisture from the air. Since both when heating or cooling your car the air conditioner compressor is working the fan will be running at high speed and makes more noise.

Why would your ac compressor lock up when the switch is turned on in your 1997 ford ranger?
The air conditioner compressor is made of several parts that need to move to circulate the refrigerant through the system. There is the pully, shaft, bearings and lifters or pistons inside of the compressor, the compressor motor has a clutch. When the belt on the engine turns it turns the shaft on the compressor which is held in place by bearings, the shaft moves the lifters to circulate the refrigerant - the most likely cause for a compressor to lock up is missing or misaligned bearings. Other possible causes, belt loose or not on properly, shaft bent, compressor motor not working correctly or clutch worn, pully stuck. Generally you would have to replace the ac because of how the serpentine belt is threaded onto the engine. Check to see if you can bypass the pully by getting a smaller belt, but it is important that the belt be threaded right for all the other engine parts to move correctly. The ac compressor usually runs about 2 - 4 hundred dollars new. You can also get rebuilt ones or go to a reputable junk yard for a replacement one.
