I made this post over at s a a b ce n t r a l . co m
So on that other saab forum (before i discovered this one ) I had posted that my rain sensing wipers no longer worked as they did before I had my windshield replaced.
At the advice I was given there, i let the windshield place know that I had a rain sensor and that it required a different windshield than a 9-5 without, they had that part right.
What the issue was (and i am sure this is the issue for everyone else) is that the sensor does not sit flush against the windshield and therefore, the sensitivity sucks or does not sense at all and you therefore lose intermittent function of the wipers, more annoying that it sounds once you lose them.
So here is how i fixed mine, and I hope this will help others fix theirs as well.
Before removing the bracket from the windshield, i took a blue sharpie and outlined the bottom of the bracket, reason to use blue is that you will be able to see it against the black sunshade better than a black sharpie, ask me how i know . Reason for this was obviously because the bracket needs to sit in the perfect position so that the sensor also sits in that perfect position to properly sense.
After I had it outlined, i simply took a razor blade and cut between the windshield and the bracket, don't worry about the black sunshade that is on the windshield, i don't think you can actually scrape that off with a razor blade. After cutting/prying the bracket from the windshield, I then used that same razor blade to get any of the residual glue off.
To prep the windshield I used alcohol prep pads, DO NOT get near your sharpie outline that you put on the windshield, it WILL take the markings off.
I then used a table sander, (i am sure you could do this by hand) to sand the glue off the bracket and actually partially sand off part of the ridge that is on the bracket to ENSURE a tight fit of the sensor to the windshield.
Walmart and many car parts stores carry "Super weather strip adhesive" which can be a pain to apply because it is stringy, but dries hard, and is easy enough to manipulate with a toothpick.
Applied a few dabs to the bracket, placed it back on the windshield matching up with my lines that I previously traced on and taped it up with packaging tape. The weather strip adhesive dries quite quickly, but I wanted to give it way more time than i think it needed and left it taped tightly to the windshield for 48 hours.
I was lucky enough were my sensor gelatin stuff was still in good shape (this is the part that "adheres" to the windshield). I put the sensor back into the bracket that was now beautifully adhered to the windshield, it was a little harder to get the sensor clamps to fully clamp in, but now the sensor sits perfectly flush against the windshield and the rain sensing now works as well as it did before the windshield was replaced, if not better .
The entire process minus drying time seriously took maybe 20 mins and i always kind of hated the rain sensing but when you don't have it, you miss it terribly.
Hope this helps anyone with the same problem i had when i got my new windshield .
