Help with 2002 Mustang V6 - Possible Alternator Issue
Hi all, I am new to this site and a woman so please bare with me. I have 2002 Ford Mustang and been having issues with it, I had a alternator put in it las year and then this past week it started to fail and had to have it replaced. Yesterday I got in the car and the heater go from warm to ice cold and the service engine light is on. Please tell me what that could be? I been told by auto zone it is the thermostat or the 02 sensor and then they said it could be the heater core, has anyone else had this issue?
