Thank you CUMan for the reply. I appreciate it.
My LS400 is 1991 (my bad for not specifying) I just checked my power accesories to see what works. My power windows and sunroof still work but now my door locks do not lock when the button is depressed. I get a clicking noise under the driver seat whenever I depress the power door locks also. So I guess one of the circuits has shorted out but do not know which one it is.
If you could PM the diagram for me, that would be great.
Again, thank you.
