I am definitely not HT, and I know that you probably know more about these "rigs" than I do, but do you think that possibly its either a computer issue (ie. you got the BCM or something wet), or the sensor (ie. they are wet or damp or something.... even though I know you cleaned them and such) or that maybe the dash is malfunctioning?

Plus the fact that it is an intermittant problem....
Do you have anything that is not performing correctly to correlate with the light?

Again... not an expert but based off standard GM OBD I would think that if you have a light you should have a code... sometimes you even have codes with no lights (Ie. no CEL on my vette, but I have a couple of codes pop up on every start up because the O2 sensors are not a fan of my headers)
