My turn signal do not always work My horn went off while the car was parked. How can these problems be fixed and about how much will it cost?

Thanks, I was reading about all the problems that this POS Alero has. I left it with a local mechanic overnight. It also has an oil leak from the engine and sometimes the radiator overflow plastic "bottle" leaks. I constantly check that there is sufficient oil and antifreeze. Although, after losing a lot of antifreeze, I just add distilled water. After paying $1200 for this car, I do not plan on spending a lot of money on repairs. I will never buy another GM car! My previous Japanese cars were much better!
