I have a 1996 Fleetwood that the keyfob / auto lock when put in Drive works most of the time , BUT occasionally quits and I have to disconnect the battery for a minute and it fixes it. It happens sometimes 3 times in a month, sometimes it works for a couple months perfectly. Kind of annoying ... Any thoughts as to what is causing it to loose its marbles occasionally ? Sometimes when it quits the locks all start making a noise like they are clicking trying to operate all on there own, But that only happens a couple times a year.
