What transparent goop/gummy-adhesive can I safely use to re-affix the rain-sensor to the windshield?

My rainsensor goop was no-longer really transparent from age (and thus not sensing rain accurately) and so about a year ago I removed the sensor and replaced the original goop with 3M clear-stickies that someone here recommended, but unfortunately they have already failed and are only holding the outer perimeter to the window, leaving slight air-space in front of the center sensor-area making it work totally erratically.

Thank you

 

The gel pad part number is LJD3850AA, I believe it was about $7 at my local dealer.

 

order the pad like davidb mentioned...but be sure to get 2...you will probably screw it up the first time you do it :-) i screwed it up the first 2 times and had to order a third :-0

 

Thank you!!!

 

My windscreen rain sensor was basically loose in the housing as it had come away from the double stick "gel" pad. It still worked pretty good.

I ordered a new gel pad and properly connected the sensor back to the windscreen.

Now the automatic feature does not work at all.

Any ideas?

Also, is there also a place the detects moisture and helps the windscreen wiper swipe?

Thanks.
