We just got our rig back from the shop at Buffalo RV. Our issue was with the night shade. It wouldn't come down at all. Both switches were dead. When we got the unit back we see that they replaced both the night and the sun shade. The new sun shade goes all the way to the dash. Both shades have a red sticker on them warning about pulling on them as they are motorized. Apparently the service side is to totally replace everything in the shade units, including the shades themselves.
