I was driving down the freeway when I heard a high pitched squeal. I pulled over but didn't feel safe on the highway by myself. I turned my car on, the noise was gone and slowly drove 1/2 mile to the next exit. When I got somewhere safe I popped my hood and found I had broken a belt. A Good Samaritan came over and gave it a look. He said he though it was my ac compressor belt and I should be fine to drive it as long as the ac was off. I slowly drove the last 30 miles home with no problem.
How do I know if it is just the ac belt? Can I replace it by myself with my limited skills? If I have to take it in, how much will it be? Lastly, I think this belt was replaced only a year ago, is this type of failure normal?
Thanks for the help!
