Now i got in to take the truck up to the installer to see if he could figure out what happened and i suddenly have nothing when i turn the key it started to turnover and then just went dead.

So I have replaced a few other solenoids on this SUV and had no problems however solenoid 3 has now burnt out 4 times, each time getting shorter from the last time. Just replacing the solenoid and spark plug is not enough. I have heard this is a problem with this vehicle but some suggestions would be great, thank you.

Started yesterday. My kid were playing with the keyless entry and now when I select the last two buttons to lock all doors do not work. Since this has happened my dash light for door ajar is always on. I am wondering if that has to do with the doors not locking with the keyless entry on door itself. I have checked all doors to verify that they are all closed as well at the truck. PLEASE HELP!! Thanks!
