    Best guess is a leak with water intrusion somewhere.

    If you are talking about the auxillary PDM that is located in the driver side "b" pillar, then the cause is a water leak around the upper bunk window that leaks straight down into the top of the PDM. When you unplug the top 2 connectors you will see corrosion. Fix leak or put plastic bag around new PDM so that water cannot get inside.
