I've posted about this before but I'm still confused on it.

Ever since I bought my 1995 ls400 I've not been able to operate anyone elses windows nor use the power lock on my side of the car. Only my power window works at my master switch. (The rest of the windows DO work though.)

The other things that don't work are as follows: ~~~~~~~~~~~~

Power Mirrors (Only the drivers side one doesn't adjust for some reason, passenger one works fine.)

Driver-side footwell light doesn't work (except for the passenger)

No Door ajar / open sound nor light on dash (except for the passenger)

Dome light doesn't work (the main dome hasn't worked since i bought the car. on or off. bulb could just be dead though :/)

Window lock switch doesnt work (Really annoying when I need to have people not use their windows)

Memory Seats

and the Seatbelt height adjustment (Again, only for the drivers side it doesnt work. Works fine on passenger side.)
~~~~~~~~~~~~~~~~

Where I'm confused is if I need to fix the MPX Door computer inside the panel of my driverside door, or if I need to fix the MPX Body computer under my dash.

I don't even know what the MPX Door computer inside the door honestly does so if anyone has an explanation of what both of these do it'd be appreciated.

I've had to replace my front right/passenger power window motor, and left front and rear door lock actuators, over the years.

If too many electrical things don't work, I'd check the fuses too. I think my car has 7 fuse boxes located in odd places all around the car.

Turns out. It was the door MPX computer, fixed all my issues plus the car killing my batteries.

Where was the MPX located? i also have this exact problem only difference is that my window lock switch does work but how hard of a job was it and where did you buy your MPX from?
