Can anyone tell me how to find out which door switch is malfunctioning. with all the doors closed the door indicator light stays on. its an 05 supercrew.im pretty sure its the drivers door just dont know how to single out which on it is

 

I don't know how easy it is to pop them out but, unplug them all and plug them in one at a time?

 

try spraying wd40 in the latches...I had the problem with my ranger, and the wd took care of it permanently...theres a sticky about it on one of the forums too
