2000 Chevy Blazer is making a grinding noise
My 2000 blazer is making a grinding noise when put into park and reverse. It doesn't do it everytime but sounds like starter is engaging. It also started itself when the key was turned one click forward. Changed the starter but no change. Also started it the other morning and all sounded good. When went out to vehicle 5 minutes later the noise was there along with a hot metal smell. Any ideas?
