what is the small vent under the guage cluster (under the temp guage), just behind the key when it's in the ignition? It is black, has 4 slots and is about 1" x 1". I just noticed it today and have no idea what it does.

 

i dunno- maybe the speaker to the open door/cars
off but headlights on sound-???

 

I am pretty sure it is the airtemp sensor for auto climate control.

 

or maybe the vent to let in the poisonous gas (part of the vehicle anti-theft device).

 

I thought it was the interior air microfilter

 

flux capacitor

 

Temp sensor

 

It's for the automatic Climate control sensor temp. I have that little thing on my dashboard but no auto climate control.

 

If it was a microfilter, it would definately be a MICROfilter.

 

True, it would have to be a micro mini me. Air temp sensor it is.
