I recently took my 2006 Pontiac Vibe in for a oil & transmission fluid change before driving from LA to Vegas. Now my check engine light is on. The mechanic also did a read on my engine BEFORE the fluid changes and it said that everything was fine. Now, what could be the possible reasons that the light is on and how much do you think it will cost?
Also, the radio will not turn on (but the clock still works) and the mirrors do not turn. I was thinking that this is an electrical problem, but could this be something that would cause the light to come on as well?
