Spinneyhill Posted June 4, 2018 Share Posted June 4, 2018 It is nearly always useful to know what car you are talking about. Link to comment Share on other sites More sharing options...
joe_padavano Posted June 4, 2018 Share Posted June 4, 2018 If you are talking about a 1980s or 90s vintage mirror, the temp sensor was usually mounted behind the grill. Link to comment Share on other sites More sharing options...

Spinneyhill Posted June 14, 2018 Share Posted June 14, 2018 How about a photo. We are guessing blind. So now it turns out it is a door outside mirror? Link to comment Share on other sites More sharing options...
rick60 Posted June 14, 2018 Share Posted June 14, 2018 I believe you are talking about the fiber optic cable. The cable connected to a bulb with a special socket inside the door. It illuminated the thermometer when the park or headlamps were on. There was no temperature sensor for the mirror. My experience was with Oldsmobile. Buick was probably the same.

jeff mazur Posted June 18, 2018 Author Share Posted June 18, 2018 the cable with this mirror has a yellow plastic tip on its end. does that sound like the fiber optic you mean Link to comment Share on other sites More sharing options...
TerryB Posted June 18, 2018 Share Posted June 18, 2018 If you shine a bright light on the cable end while in an area not getting direct light you should see some illumination of the temp gage if indeed it is a fiber optic cable. The glass like fibers in the cable will “carry” the light to its destination. Link to comment Share on other sites More sharing options...
