seat heating not working - Toyota Yaris Forums

Hi.I have 2007 Yaris TS. I live in Europe.
Have heat seating on both front seats. It was working good and now suddenly it dont work no more. I tried reading through maintenance manual that I snapped from here but from 316 pages about seats none mention seat heating.
How can I troubleshot seat heating ?

I need also fuse box explanation? Somebody have it? Could it be blown fuse maybe ? Is the fuse for seat heating in fuse box in engine department or where?

I checked wires from underneath the seat and are all connected good...

Thanx

The seat heaters are fed from the P S-HTR (right seat) and D S-HTR (left seat) fuses. If you are not seeing the lights illuminate when you press the switch, then I would check the fuses first.

Do you have heaters in both seats, and do both not work?

Thanx. Yes seat heaters in both seats. I was testing last night,passenger seat is heating. Driver seat is not heating. There is buttons for left and right seat and both illuminate when I press them on. But yet driver seat remains cold.
Any clues ?

If the light comes on but the seat doesn't heat up, I would suspect that the heater is bad. The light and the heater are connected in parallel, so the light will still illuminate if the heater has open circuited. If it short circuited, it would have blown the fuse, and the light would not come on.

Ok thanx.
I still have 6 moths left of guaranty so I'll go bother dealer.
Thanx again.

edit:
actually I dont even use this heating (I have a hot ass,hehe).
But I wonder if this can go on guaranty thought ?
I didn't misuse heating or something like that. It worked last spring ok.
This dealers here are pain in the ass ,I hate going to them.
