Hi there,

On top of the dashboard on my 94 GS300 are two small circular areas that appear to be sensors. On the driver side, the sensor appears to be for detecting how bright it is outside for the Automatic Headlights. What's the one on the passenger side for? When I first got my car, it had a little plastic bubble over it, but during a car wash it somehow broke off. Any clues what this is for?

Thanks,

Without that little plastic "bubble" (filter??) your sunlight detector is too sensitive, that's likely why your A/C is over-reacting.

 

Are both sensors supposed to have the "bubble?" I think only one of mine does, I have a first GEN like Silmeron.

I don't think both are supposed to, just the one on the passenger side. I've never had any problems with my automatic lights (other than rush hour and getting stuck under an overpass and them popping on and then popping off once I get out, potentially irritating the driver in front of me )
