USMav...on the driver's side or passenger side? I seem to see what you are referring to...

20Blazer...I'm not sure to be honest...when it was decided to do that, I was out smoking a cig...when I came back, we were able to get at it. Why?

 

disconnect the battery for 30 seconds and it'll reset everything...that may turn the ses light off if you fixed the problem.

 

cmsweet, that sensor is on the drivers side, inbetween the middle plug and the last plug on that side
