Has anyone seen a difference in the way their electric windows work related to the moisture in the air? On the 87 I just got, the windows were pretty much non-functional until I pulled the door covers and worked everything over with silicone spray and a lot of exercise. They've been working great the few days since then until today. It was misty and damp this morning and the windows were very sluggish and the RR didn't want to work even with manual assistance. I'm thinking the covers come off again and cleaning the switch contacts is in order. Any other ideas?
