Having an issue where the drivers side seat warmer does not work but the passenger side does. Manual suggests they’re on one fuse so if the passenger side is working I’m assuming the fuse isn’t the issue. What else should I be checking? Know nothing about cars but really hoping to avoid taking it in and spending a bunch of money.

 

One fuse powers both.

Check the power wire to the seat heater for 12V when switch is on. Its a blue wire. The ground wire for the heater is white/black. Make sure the wire grounds to goes to chassis ground. There will be a plug connection to the heater.

Yellow wires are airbag thus don't go poking there.
