I know this thread was all but dead, but Ihad this problem on my navi that had gotten so bad I was pulling the fuse to stop it. I then tried this (long before I knew about this site, damnit) and slammed the doors a few times and now it only happens intermittantly every few months and even then it usually goes away. The guy at ford told me the switch was magnetic and that they frequently had this problem. Slam the shiat out of it once you have sprayed it real good, and if that doesn't fix it, take it and get it fixed. Its an aggravating SOB
