2005 super crew...bought truck for my son....the button on the dash stays off....replaced all the sensors, still stays off...I have done some research and found that it's possible for the speaker to be faulty....for $20 I'm going to give it a shot...where is the speaker located on this particular truck? Also noticed water on passenger side floor...no it's not heater core related...anyone here had this trouble before I take out whole interior to find out where it's coming from? Water is in wiring channel in floor that runs along doors...also wet in rear channel. Third brake seal is good...headliner not wet. No sign of any previous damage/body work...thanks in advance!!
