woody Posted June 1, 2005 Report Share Posted June 1, 2005 All, Has anyone encountered the "Service Engine Soon" light comming on? I have almost 90,000 miles on the car? Is there a way to reset the counsle light or do I have to take it to the dealer. I thought maybe it was because the miles were close to 100,000 that it triggered. Any help would be great.

Any codes stored will be displayed on the information center. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...

woody Posted June 1, 2005 Author Report Share Posted June 1, 2005 KHE & Ranger, I just did the test and would like to know if these are serious or just checks? I know my drivers seat power just went out and may be triggering the light. I am thinking if I get the power seat fixed it will reset?

Ranger Posted June 22, 2005 Report Share Posted June 22, 2005 It is located on the rear cam cover, next to the coil pack. It just slides off of the mounting braket to the left as you are looking at it. It has an electrical connection on top and three vacuum hoses connected to it. I think the rear one is just a vent. Just remove it, swap the connections and slide it back on. Should take all of 5 minutes, no tools required. Link to comment Share on other sites More sharing options...

caddypete Posted June 23, 2005 Report Share Posted June 23, 2005 First make sure your gas cap is properly closed, that will set it off. Link to comment Share on other sites More sharing options...
