Does anyone know where to get replacement levers for an Infiniti G35, NOT the one on the back but the side closest to the window/door, it broke in half, slipped out of my hand and broke!!

Downloaded a PDF detailed service manual online. Gives you diagram and everything else you need.

SOURCE: Driver's seat unable to move forward or backward

There are plastic gears connecting the track to the seat assembly. Whne one of these strip the seat will only work or move to one side. Infiniti does not sell a simple fix. You are looking at buying an entire seat assembly complete with the module for all the electronics. It will be at a cost of around $950 - $1000. Once that is in, Infiniti must program the seat to the brain of the car, only then can you reset your memory settings.

SOURCE: my window on 2005 infiniti g35 stop working

I have a 2004 G35 Coupe that had the same probelm.

I checked some fuses -- all appeared to be OK. Then tried locking and unlocking the driver-side car door several time, using the key and the car fob.

Presto, the window stared working again.

Caution, I believe there is an issue (at least with the coupe) about raising windows while the door is open and then closing the door.
