#1 of 2 Service Engine Soon Light by larrykeller Apr 13, 2009 (11:07 pm)
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? Replies to this message: burdawg (Apr 14, 2009 5:33 am)

Replying to: larrykeller (Apr 13, 2009 11:07 pm) 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.
