I have searched the forum and only found minor info on this matter. It feels like my driver's seat heater is on at all times, especially the lumbar heater. Anyone else experience this symptom ? Read that pulling the seater heater fuse might be the fix.

have you tried turning the seat heat ON to feel the differance?
the driver side gets butt and lumbar- passenger only butt heat
Check owner book for details on how long HIGH is ok to use then switch to low

Seems to be a pretty common issue as of late. Pull the fuse listed in the above thread and see if it helps. If it does take it to the dealership and have them look at it. If it doesnt help it is probably in your head because that fuse is for the heated seats.
