All vehicles manufactured since '96 and newer have a diagnostic connector under the driver side dash that is *almost* in plain sight. Buy a code reader from amazon for $17 with shipping and plug it into the connector in your vehicle. Read the fault code or codes that may be stored. Update this same post with code number info. If there are no codes stored, state that. If your code reader is unable to establish communication with the code reader, state that also.
