I'm having an issue with my seat heaters. Most of the time when I turn my drivers side on, the lights will stay on for a couple of seconds then turn off.

I would assume it's just an issue with the driver's side seat but when I turn the passengers side on the lights stay on until I turn the driver's side on then the passenger's side turns off.

Any help would be appreciated.

Thanks in advance,

Kevin

My guess would be you have a short in the wire from your front seat to the power source. And when you turn it on...after the power kicks on....you might have bare wire somewhere shorting the connection. And as for the passenger side staying on until you turn the drivers side on...The drivers side is probably kicking a "fail safe" in the power system and shutting both sides down. Either that or your heater is going bad.

I was having problems with mine to. Both seats quit working and the passenger side door light would stay on after you closed the door. I took it to the dealer and they had to reprogram the module for the interior and I havent had a problem since.

All the controls, electronics, are in the driver door. I lost all function in the passenger door and the control module in the driver door needed to be replaced. Ouch on the price, over $500 for the part. I had no window, locks or heat control.

Is there any way to test the element before I go through the trouble of replacing it. I noticed the seat does heat up for a couple of seconds before the light goes out, so it is working just not staying on.

Since all my other electronics work properly I would hope that I won't need a new control module.

Tell me about it, I carpool with a guy who keeps turning it on and telling me about how nice and warm his seat is , so I just push the drivers side button and his shuts off :moon. I guess there are advantages to having this problem.

I am having the same thing with my 04, sometimes it works and sometimes it will not. I am also having a problem with the wipers, when you turn them on they will not go off. Leave it overnight and the next day they will be off , but if you turn them on again they stay on.

It is probably a reflash issue. Pretty big problem with them in the 03-05

That is also covered in the reflash, I have had that problem in all 3 of my Dmax trucks. The NBS is not different.
