My infinity fx35 2004 door locks do not work when I try to use the control panel on the driver's side. The switch only controls the driver's side door the other doors have to be locked manually. The back hatch does not lock. Does anyone have any ideas of how to solve this problem. Thanks

Sounds like you have a lock actuator issue... do a search and you'll find a lot of info on it...

If doors do not close/open with remote and master control then Mabuchi motor FC280 inside lock mechanism no longer has enough torque. The motor can be purchased of ebay. The motor uses spline shaft and rotates right when viewed from back (+12V right upper). I replaced motor on on my passenger and rear right door. It is not easy, and requiers opening lock assemly that is is not designed for repairs. But it cost me $25 for motors (bought 3 of wrong kind), instead of $200+ per door for parts.
