Hello,
I have this 2006 G35.
The driver seat makes me crazy. I have electric seats.
While driving after about 30 miles (quite repeatable), the inclination of the seat starts moving by itself, increasing the inclination slightly then more and more...
it is very annoying and unsafe because it really distracts you while you are driving.
The problem is that I cannot bring the seat back to my memorized settings because the mem setting does not work anymore in this case. Also I Cannot adjust inclination manually because the inclination switch does not work. To have it work temporarily I have to press the seat lift switch either down or up then in this way the inclination switch will come back working again (for a while). So it's "working" pretty funky.
What can be wrong in here ? the electric motors are working. Could it be a wiring harness issue ? Or a switch problem ?
Anyone had this kind of problems before ?
thank you

 

The first thing to try would be go to an auto parts store and buy a can of contact cleaner. Spray it liberally into all of the seat switches one at a time while you are activating the switches. Food, dust and other assorted crap can fall down in the switches and cause all kinds of issues with the seats.

 

The switches can go bad due to issues Blue Dream pointed out. Might even be able to still buy the driver's side seat switch new from Infiniti. For the passenger side, I had to go used since Infiniti doesn't sell the passenger side separately, they wanted me to buy the whole seat bottom assembly.

 

yeah I think if the contact cleaner solution will not work, I will have to buy new switches.
But then installing ithe switches module will be a nightmare. I am not able to do it myself.

 

Fair enough, find someone who can handle a screw driver. Tell them to: unbolt seat, lean it back, unscrew switch assembly (2 Phillips screws), unplug switch harness, replace, cover screws with high quality electrical tape (or buy the precut piece from Infiniti), pay them $50.
