Both heated seated stopped working at same time!!

Truck: 2017 Toyota Tacoma TRD Sport.

Issue: Both Heated Seats Stopped Working at Same Time

So today I got in my truck and realized my heated seats stopped working.

The dash shows it turned on and lit up but not getting any heat.

I turn on the passenger side and again dash lights up and but heats don’t get warm.

I’ve never used the passenger side.

Might be a coincidence but last week my AC stopped working.

Dash will show AC is on but no cold air.

I changed the battery last year

Any help is appreciated.

 

Original Battery???

 

nope changed the battery last year

 

Check your fuses.

 

Check the no brainer stuff; fuses, battery (just make sure), harness connections to the seat heaters, etc. But my bet is on mice damage somewhere. There has to be a common denominator here. Good luck!

 

would you happen to know if there’s more than one fuse for the heated seats.

I could only find one fuse for the heated seats in the fuse box located underneath the steering column.

No fuses for it in the engine bay.

The control box is also known to be a failure point. https://www.tacomaworld.com/threads/factory-heated-seats-failure.528038/
