Power Window help

[jdebellas]

I'm a new user and have found the forums very helpful. I own a '91 q45. My driver's side front window will not go down, the latest in a long line of electrical woes. I assumed it was the motor, so i have removed the regulator and bought a new motor. Also, installed a new switch.

However, when I plug in the new motor and flip the switch, nothing happens.

I have noticed that there is a plastic white box mounted underneath the armrest that clicks when i flip the switch. It is labeled:

AMP ASSY AUTO P/W28515 60U00ET881 12VJIDECO

It has eight pins on one side and plugs into the door's wiring.

When I took it off and shake it gently, it rattles. I suspect this mystery part is the cause of my problem. Does anyone know what this is? If so, could this be my problem, and how do I get a new one?

Think you'll find some posts on this in Infiniti Online Mechanic Forum.

Welcome to NICO

Here is a link to a G50 Q45 FSM, just in case you don't have one already. http://phatg20.net/modules.php...d=203

Thanks for the FSM (what does that stand for?). I read through it and it looks like that thing is called the LCU 01B.

The FSM was for a 94, but it looked like everything was similar. Thanks for the help.

Factory Service Manual

The "LAN" sections of the '94 aren't applicable but almost everything else is.
