#1 of 8 Service Engine Soon Light by larrykeller

Apr 14, 2009 (12:07 am)

I have a 2001 GrandAm with about 79k miles
My SES light just came on, engine runs fine, no problems, but concerned about the light. Also, my heat/ac fan switch has stopped working on 1 and 2, works fine on 3 4 and 5. Any connections there?

For the SES light, check the fuel cap to see if it's on properly and the seal isn't cracked or otherwise damaged.
The fan problem is most likely the fan resistor board, which has been discussed in this forum many times, but under other topics.

the service vehicle soon light came on cause I had a headlight out.
The tech told me that any time any sensor goes out, such as a headlight, the service vehicle soon light comes on.

A headlight isn't a sensor. I've had headlights go out, and have never had the service light come on. Was the OBD read for the diagnostic code?
