Not directly. I don't suspect the switch or the fuse. The seat back heat works and the lower cushion does not. I only found one fuse listing "Heated Seats" so I suspect that all four heaters (2 driver and 2 passenger) are power via the same fuse. The switch appears to be a low voltage system (not direct drive to power the the seat heaters) as this model has three levels of heat. Each time I press the switch the heat level changes (off-high-medium-low-off-high- etc.).
Right now the most likely suspects in my book are the heat controller or the heating pad itself. But I can't quite figure out how to get it all apart. I purchased (ie., wasted my money) the Haynes manual. It has nothing about heated seats in it.

The power for the heated seats comes directly from the battery via a 30 amp fuse located under the hood. I would agree that this is not the problem and it's either the heat element or connector.
There is an 18 step diagnostic to trouble shoot this problem. If you plan to work on this truck on your own I would suggest buying one of the following manuals:
Helm factory manual
I would recommend either of the first two while alldatadiy has most of the factory info online but not as comprehensive as the first two.

Thank you for the help. I was looking for a better manual than Haynes. They really stink. Other than torque specs, they're not good for much else.
By the way your first two links are the same. Can you repost which ever option is missing, please.

Oops sorry about that.
Haynes couldn't even give me the right location on a thermostat for a Nissan truck. Never ever bought them again.

Try cleaning or replacing the idle air controller.

The drivers seat is electrical. The seat will only move up and down. Can not see any debris on tack. .Ttook seat apart, still could not see problem. It feels as though it is hanging up on the left side. Any help and suggestion would be appreciated!

First off. How did you change the cap and button on a truck that does not posess a distributor? When they started installing the coil packs in fuel injected motors they ruled out the need for a distributor.
