Where is it located?

 

I'm not sure if it's the ambient air temperature sensor you're talking about (when you press the button on your HVAC, it'll show outside temperature) or not, but said sensor should be near the driver side headlight on the radiator.

 

88625Q is the interior temp sensor

 

What fortitude posted makes sense, sorry for any misinformation!

 

thanx - what is the button-looking thing on the dash for? I seem to only have one which I think is the light sensor for the lights.

 

I believe so

 

Then why is it shown on the diagram locating the temp sensors??

So they're saying the light sensor has some kind of temp sensor in it also??
