update & ping
figgered out the external lamp warning - it was the third eye brake light. although it was working when i checked it, i caught it when the warning came on and saw that it (third eye brake light) was not coming on (you can see the light through the bottom of the cover). after a second it was working again so i just changed it and that took care of that.
in the meantime after the recent "heatwave", my external temp sensor has not recovered as i thought it would with the cooler dry air. anyone have a partnumber for that thermistor? is that the same thing as the "ambient temp sensor" in fastlane? it's $45 and i know the thermistor is just a couple of bucks....
