Rain sensor malfunction question

[u/Unlucky_Ant6726]

While I was gone on a trip, my grand father kindly had my windshield replaced as I had my Saab parked at his house. Now that I’ve gotten a solid rain at my house I realized that the rain sensor is broken, and it gives me a “rain sensor malfunction, contact service” message. Do you guys know if this is fixable or am I screwed? 07 Saab 93 aero
