Frank Posted January 29, 2005 Report Share Posted January 29, 2005 The rain sensor is not working properly after having a new windshield installed. I used to set it on the middle setting and it would keep the windshield clear-come on intermittently or stay on, increasing speed as necessary. Now, in a steady rain, it barely keeps the windshield clear on the highest setting. It also runs only intermittently-never constant. It is installed in the sweep of the windshield wipers but in the tinted area of the windshield. It is mounted 1/8" from the rear view mirror mount (passenger side) and the base of the rain sensor is 1-1/8" from the base of rear view mirror mount. The factory manual states that it should be mounted 2-3/8" from the rear view mirror mount and the base of the rain sensor should be 3/4" below the rear view mirror mount but the electrical connection won't reach that far. Any help on why this isn't working properly(location?,installation?) would be appreciated so I can go back to the installation company to have it corrected. Maybe someone with a car like mine can tell me where their rain sensor is mounted. Link to comment Share on other sites More sharing options...
WarrenJ Posted January 29, 2005 Report Share Posted January 29, 2005 There have been several posts on this subject. You'd likely want to do a search. Bottom line: it is imperative that you use the GM adhesive to attach the sensor to the windshield. I don't think the physical position of the sensor is very important. However, the optical properties of the adhesive are critical. Regards, Warren EDIT: Pay particularly close attention to posts by "bbobynski" on this subject.

adallak Posted January 29, 2005 Report Share Posted January 29, 2005 The rain sensor is an optical device. Moving from untinted area of the windshield to tinted one may have a dramatic impact. Close attention should be paid to the quality of the optical contact between the sensor and windshield (there should be clean uniform layer of a specified optical glue between the sensor and the glass).
