Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.Glenn,If the check engine light is coming on then you have to have a fault code and or codes. I am not sure why they are telling you there are no fault codes. The light comes on when the computer sees a system fault and the computer will set and store a fault code and or codes. I would consider finding a different dealer to check for the fault codes. If you can get the fault codes we can help you determine the cause.
