Admittedly, I got a kick out of this while at the same time thinking its insane. The rain sensing wipers on my car have not worked since I bought it. I rarely drive my car in the rain, but still wanted to get this fixed at some point.
I narrowed it down to either needing a new sensor or needing a wiper module refresh. Since a used rain sensor can be obtained fairly inexpensively, that seemed like the logical place to start. I just need a new adhesive pad, right? Called my local Jaguar dealer, and after some investigation, they don’t offer it. Turns out you have to buy a brand new rain sensor to get the adhesive pad that comes with it. Crazy! And if you’re wondering, a new sensor costs hundreds of dollars. I asked what they do when they have to change windscreens on a car, and they said they try not to damage it and just reuse it. Talk about goofy!
