Both seat heaters aren't working

Out of no where my seat heaters stopped working. I flipped up the seat and the (blanking) connector is in good shape. The lights by the climate control show the three bars.
I guess what I'm asking is if anyone has a diagram of where I need to look. I found the fuse..but it's in working order. Don't know if there's another fuse or relay somewhere.

Thanks

 

Warranty? If so don't do touch it and take to dealer.

 

Unfortunately my warranty was up 500 miles ago

 

Still take it. There are times they will do a goodwill warranty work call and ask. It's still close to the milage .

 

Sadly I tried that, anyway I'd rather not give it to them since they left my skid plate loose and and left oil everywhere. Rather just see how complicated it is to track down possible sources. Then decide

 

That sucks .

 

I don’t know if there’s a fuse that control these, but I’d check that first. It’s not common that both would stop working at the same time, so I’m betting a fuse somewhere is blown.

 

I found a couple threads on this here: https://www.tacomaworld.com/threads/driver-heated-seat-not-working.533672/ and here: https://www.tacomaworld.com/threads/factory-heated-seats-failure.528038/

Godspeed!

 

Thank you,
Unfortunately my amp is clean as a whistle. The 2 dealers around here are kinda shady but I guess I can bring it by. Or wait for my trip to CA where I bought her

 

Might be 2 sets of fuses, one for the switches and another set for the relays.

 

I was thinking along the same lines as you. Would be interested if it's something I can do.

 

Quick search, looks like for 2nd gen though but it may be the same.

Looks like fuse 7+29. 30A and 50A

 

Thank you, I'll have to look for that when I get home. My heated mirrors were always going and kept killing my battery. So maybe the techs at Toyota forgot something

 

You could just measure all the fuses, but those appear to be the ones to check. Sounds like maybe the mirrors are hooked to a constant 12v supply? Odd.

 

There is a TSB that addresses this, it involves replacing both seat cushion heaters.

I would start with checking for power to the seat, and checking ALL fuses with ignition on and using a test light.

 

Apparently they had to pull the driver side dash and found out the relays or fuses were corroded causing them to always be on.

I'll do that tomorrow as well. Figures the seats go out and there's a tsb..

 

So I have an appointment this week..dreading it..but on the topic of fuse and relay locations, are the only spots under the hood and the narrow fuses under the dash?

 

Stop by Taco Bell. “Heated” seat problem solved!!

 

But that's a short lived "fix"... plus the added cost of air fresheners...

 

Crazy, that'd have to be so reasonable corrosion to bridge a constant to a switched circuit. Might explain some of the issues your having now. Other thing you could do, if you have a volt meter and know which plug goes to the heaters, you could measure the resistance from pin to pin. This would help rule out a short in the heater element, but I doubt it since its both cushions.
