Passanger side seat heater not working

Hi all,

I've been looking around online on this issue without success.
My passenger side heated seat is not working since i bought my car 2 years ago.

The light in the switch does light up but no heat is ever generated (i know back is not heated).

Could it be a fuse? if so which one?
Could it be the cable disconnect under the seat? if so which one/where?
If not what else could it be?

I'm hoping its not the actual heating element as the replacement looks quiet long.


Thanks for your help!
MM
