passenger side window lock not work

[tulanch]

hello,

i have a 2003 4.4i. The driver side control will operate the driver side windows and the back passenger side window, but not the passenger side front window. Yet the passenger side door switches both front and back will operate their repsective windows. Also, neigther of the power locks on the passenger side will operate with the center lock switch.

How can I trouble shoot this?

I have already removed the driver side switch and it appears that all connections are fine and being it's a micro-board switch unit, theres seemingly no mechanical aspects that could be dirty or corroded. This unit is pricy, so if there are ways to determine if the problem is else where I'd like to start there.

Also, how do the power locks work? Are the direct-wire connected or are they remote controlled from the center switch?

Anyone know of any wire schematics of these features to review?


thanks for any advise
