Heated seat problem

Just bought an 04 Envoy SLT. I am totally delighted with this vehicle except that the seat heat in the driver seat does not work. Pass. side works fine. The little lights in the switches all light up and stay lit. However no heat in seat neither backrest. how do i properly diagnose this?

It's nothing unusual for a heating element togo bad, because of wear + tear on the drivers side.

For the short, you can go to Dicks Sporting Goods and pickup a orange hunters seat!

Check for 12v and ground at the seat heating element .
