When it rains, there are puddles of water on the passenger side! Cannot figure out how the water is getting in..my concern is of a potential electrical short/ fire / failure of a system that doesn-??t allow me to operate the vehicle safely! Possibly, affecting other functions of the vehicle during operation!

Vehicle was last driven on June 23 2024 and parked in my driveway. On the evening of June 29 2024 my horn was blowing in my truck at around 10:30. While I was walking out to the vehicle it was in flames. The fire started from what I understand on the driver-??s side behind the dash. Luckily no one was in the vehicle when it happened.
