Leaking Cab Over Lights

Hey for all of you that own a truck with cab over lights...I want to pass something on. My 02 Dodge 3500 (getting old), has an overhead console with a trip computer in it. The weather has been very wet with record rainfall and I came out to the truck with water dripping from the display area. I wipe it up but as I start it up, the whole system shorts out. The instrument panel went completely dead with error codes no one wants to see. Airbags, ABS, check engine with other errors on the overhead display. Nothing worked so I shut it down as fast as I could. I learned how to remove the overhead and dried out the trip computer. I reassembled everything and lucky for me everything works but now but I still have that check engine light. Lucky for me I have an OBD reader so that I can clear the fault codes so I did that. Now everything works so now time to track down the leak. Well here it is..they use these plastic washers under the screws that over the years have failed (broken and brittle), and water is getting in through the screws. I highly suggest that if you have an older truck that you replace these seals. It could be leaking and you might not even know your getting wet on the inside of the cab body.I went with rubber o-rings that will seal better but I will do this now on a regular basis. Hope this finds you all well...
