After driving in heavy rain. During the following day started having electrical issues the parking lights would stay on even when the switch was turned off the driver's side headlight would also come on. And the parking lights would either turn off or flash when the high beams were turned on this happened with front and back parking lights the only way to fully get them to stay off was to pull the relay or disconnect the battery. The problem is with the power distribution center and front control module the poor design allows them to corrode damaging the copper tracing and causing shorts in the system this is a common problem as there are several online forums dedicated to these problems with a lot of people having the same issues so I'm not sure why there hasn't been a recall for this since it is a major safety problem when it affects lights, windshield wipers and several other things that could cause accidents. My brother's truck is also having sign's of the pdc and fcm being bad. And at over $1000 to replace both for a manufacturing defect it's not right that Dodge customer's should have to pay that bill. I'll be attaching a picture of another board but the damage is the same and in the same spot.
The dashboard is cracking and caving in on itself as a result the lights go on and off while driving. Several other electrical problems are hapening.
