I have a little black bos attacht to the windshield behind my mirror??? anyone know what it is??? thanks Rick

 

its a rain sensor- it has an infrared red light aimed at the windshield,when it starts raining,in sense's it and turns on

 

OK turns on what????

 

your wipers,here this will help you www.howstuffworks.com/wiper4.htm

 

Its part of the Compass/Temp. Its a sensor. We don't have rain sensors.

 

Cool... I didn't think we had rain sensors.... if we did mine are broke... its been raining its butt off

 

really? I thought that it was a part of the auto dimming mirror...

my stock rear view mirror doesnt work any more and i was going to remove all of that crap in place of a normal, manual mirror...if i remove that, is my comass/thermometer not going to work properly?

 

Now that you mention it, Im not sure. Ill scan through the service manual and look for the electrical diagram. I totally forgot about the auto dimming mirror.

 

OK, its the compass.

I think the mirror is self contained... only the wires going to it... my vote the compass/temp
