Hi My heated seats turn on but turns off again almost immediately. I can hear a relay click twice. Both seats are like this. Once the driver side heat stayed on for 3-4 seconds but normally the off turning is instant. Same regardless what button I press. What is the most likely culprit? Getting close to winter now so I would really like the heating to work.
 
You have a burned out seat heater element.

First time mine did this, it was the driver's back seat heater element.

A year later, it was the driver's seat bottom heater element.

I replaced both heater pad elements and they have worked fine for years, now.

You will notice, the passenger seat will also not work properly.

When one element is burned out, the entire system is effected.

Check out this troubleshooting video from The Seat Shop.

That should get you started.
 
Thanks alot!  (y) Any recommended replacements? Only seat elements and not back elements?
 
I bought Dorman replacements off of Amazon.

Since that time, The Seat Shop began selling their own.
