One problem related to wiper has been reported for the 2004 Mercury Marauder. The most recently reported issues are listed below.
Wipers continuing for two years to occasionally turn on and off without switch activation. Although the issue is well documented in many of the forums for Marauders, the fact that Ford has made no recall is shameful. Only known fix is to remove the fuse when the wipers are not needed, though it is something that should have been recalled and repaired.
