It almost never rains here in So. California, but we are getting a lot of heavy rain (and should continue for about a week). My wipers are clean and the windshield is spotless, but the wipers make that annoying sound (MBZ does this too). We normally switch to a higher quality Bosch or Rain-X blade. I cannot find the size or part # in the manual. Does anyone know what other blades we can put on the I-Pace. The stock Jaguar blades suck. Btw, BMW blades are the best....so quiet!
