Air Conditioning problem
1997 Toyota Tercel 4 cyl Front Wheel Drive Automatic 141000 miles
My AC is AMAZING, when it works. The light goes off all the time and immediately the AC doesn't work--it blows hot air (or air that feels hot). I click the button dozens of times and sometimes it will work again. ALSO. The car SQUEALS TERRIBLY when the AC is on--whether it's working or not. But as soon as I unclick the AC button, the squealing goes away. How many problems do I have? HELP. It's hot this time of year!
