G35 sedan driver seat wont go forward/back

First and simplest thing is to check fuses for power seat; there's 1 in the engine compartment and 2 (forward/backward and tilt) in the interior, passenger side fuse box. Check your Owners manual for location.

YOU CANT REPLACE THE LIGHT YOU HAVE TO REPLACE THE WHOLE SEAT AS IT IS ONE FUNCTION.

It isn't wired wrong. Mine does the exact same thing, but it didn't used to be backwards and the wiring has never been changed.

There is a cable or bar under your seat that synchronizes your seat latches and it has to be tight to make both latches open at the same time. Try bending it back a bit and taking up the slack.

this is not uncommon and the test is very simple. The seat motor often fails in this vehicle and the simplest test is this: (1)raise the front of the seat as much as possible, (2)tap on the motor housing while holding the seat slide button (seat motor you need is the one easiest to reach in the front/bottom of the seat). If this resolves your problem what you need is a seat motor. Unfortunately these are often only available with a complete seat base system, so if this is the resolution you may want to search salvage yards, this piece can be easily replaced by itself.

You can move the drivers seat back by turning on the power, getting in the seat and position your feet firmly on the fron flor with your back firmly against he seatback, and then engage the switch pushing back - while pushing like hell with your feet. You can actually hear the seat drive shaft turning while the seat moves back. The principle should be the same for moving forward, but pressure would have to be aplide to the back of the seat.

is look like a fuse blowen you need to replace it look in the munual book

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.

i just fixed this problem - the switch is bad - take out the seat - 4 bolts on the bottom 4 corners and then remove the whole switch - either buy a new one around $200 or unsauter the switch and clean it but be careful as there are a lot of parts inside that can fall out. i cleaned mine and it works fine beats spending the money.

the seat adjustment motor which is mounted in the foward part of the lower shroud of the seat has two drive worm gears which are made of a heavy coiled spring if either one of these become loose or the drive portion becomes damaged that side of the seat wont drive in either direction
