I was driving my car today at 30mph and it started smoking. I pulled over ASAP, but heard a high pitch squealing noise. My A/C works good and I was using it when this happened. If my thermostat is bad would it make the squealing sound or it is my fan motor? The radiator and the overflow were full and I do not have any leaks. When the squealing noise happened I did notice a difference in my A/C. I was not able to look under the hood, since its dark and raining cats and dogs. Please advise.
