My car's heated seats, both driver and passenger, are not working.

The switches light up when I turn them on, but the seats don't get warm at all. I check the Seat Heater fuse and it's not blown.

Does anyone have any idea how to troubleshoot this? I've searched but could not find any good info.

Thanks,

Im pretty sure they only work at a certain temp...I think its below 55 or something not sure

 

Maybe the actual seat heater element (pads) in ur seats finally took a crap
I mean the only way to tell is if u trace the power circuit, you know. Power to the switch, from the switch to the connector under the seat. if its all good then ur seat pads are toast ( no pun intended)

 

I think you're absolutely right. I have the same complaint with the heated seats. I leave them on at all times, but they just don't get warm enough (or really warm at all). As the weather has turned colder here in Chicago, I've noticed that the heated seats have all of a sudden come to life. I suppose it could just be the temperature differential (i.e., it's colder in the car, which makes the seats feel warmer), but I don't think so.

 

I don't know about this. I usually turn them on when I come back from playing a few holes of golf or when my lower back is sore from doing some yard work. The temp is usually well above 55 and I never had a problem with mine coming on.

 

Same with mine in the '01 GS. They get warm not matter what the temp, just have to turn them on. I do wish I had a thermostat type control like the new models do, they are eother on or off.

 

Is it correct to assume that the heated seat feature is the same for 98--05 GS?

I will say I didn't have them on my 400 but I have them on my 430 and I freaking love the butt warmers.

The girls approve too!

 

Don't assume anything. Either one of the GS wizards here will chime in or you could contact Lexus. Not sure if the owners manual says anything about the heated seats being temperature sensitive.

 

GS 430 has heated seats?















seriously, I have never ever turned mine on.

 

My heated seats will only come on if the outside temp is 72' or below. At one time I thought they were broken too.

 

The manual does not say a thing about the heated seat being temp. sensitive (if this is the case).

The heated seats are somehow linked to the outside temperature, because they do not work in the summer, but around early october when it starts getting cooler they start working again....

 

The heated seats feature must differ from year models. Mine ('01) works anything over 65 degrees.

 

That's what I think. Hopefully someone can confirm.
