Hello, I have an issue where if I do not start and drive the van at least every couple of days the battery goes dead. I have replaced thebattery a couple of times and it does not appear to be my problem. The only odd thing I notice is when I start the car or shut it off the wipers tend to make one swipe, I checked to ensure the wipers are not on. They are not. Also when replacing the battery the wipers made one swipe upon initial connection. Is there a common problem with this or am I going down the wrong path?
