Dashboard Sunlight Sensor.

[Steve S.]

Hi All,

        Following otherwise successful heater matrix swap, this item has gone walkabout.looked everywhere! Anyone got one spare? It's the flat one, size of a thumbnail, fits flush with dash close to front windshield. for a mk 1 galaxy.

Do you know what the function is of the sunlight sensor? What does it do? (I'm just wondering about that for a long time)

 

And I'm afraid I can't help you. Mayby you can try the scrapyard.

Hi Orbis,

             It's basically a photodiode which converts the change in sunlight intensity into a (variable) electric current then transmitted to the A/C control module.Works in conjunction with other sensors i.e.cabin temp. sensor and ambient (outside) temp. sensor. I suspect all three are only present in the fully automatic A/C equipped cars not the manual only ones.

             I've no idea whether mine actually worked before it disappeared but I need to cover the hole in my dash!!!!

                 Best regards,

                                      Steve.
