So my drivers heated seat doesn't work, passenger does. I searched the forum and looks like the fuse is under the seat. Just thought I'd check to see if anyone can offer any tips for this before I delve into it.

 

The seat heater pads are wired in SERIES.
My guess is that an element has failed in the cushion or squab and that renders it INOP.

DORMAN auto products makes a generic replacement seat heat pad set but I think the DORMAN is wired in Parallel for HIGH and series for LOW?
