Minor issue started during heavy rain last week, went out in morning and power steps would not function. After starting, the rear sliding window opened and would not shut. Researched solution and reset the steps in the computer. Let truck sit for 5 hours at work (not raining) and apparently circuit dried out and window was able to close. Fast forward to Thursday night (4/1), flood rains had started. On the way home from work, the rear sliding window started opening again by itself, but was able to close it with the switch. It did this several times. Went out to start the truck Friday evening and all i got was flickering lights that dimmed when the start button was pushed. No controls worked. By Saturrday morning, there was no lights or any control. all electronics are non-functional. I checked and the batteries are fully charged, so it is not a battery/alternator problem — I expect water has infiltrated into the electronics/computer. Luckily, this short out did not happen on the whole system while I was driving.
