Toyota Seat Heater

[DHPMARINE]

The drivers seat heater quit on my wife's 1999 Toyota 4Runner SR5 Limited Edition.No heat,no light indicator on dash.No mention of being on a fuse in the (quite detailed) owners manual.Everything else seems to be OK (electrically).<br /><br />Any ideas?If I could get a wiring diagram somewhere on-line,I could probably track it down.<br /><br />DHP

Re: Toyota Seat Heater

Are you sure this is OEM and not a after-market install?

Re: Toyota Seat Heater

The way the switch (hi lo rocker) fits the dash cut out,and matches the other switches,yes!<br /><br />DHP

I would say "gotta have a fuse somewhere"<br />Could be an inline somewhere.

Re: Toyota Seat Heater

Is there a wire connector for the heater under the seat? Sounds like a power problem if the indicator on the dash doesn't illuminate and the heater is out as well.<br /><br />Your local library should have some shop manuals if nothing else pans out.

Re: Toyota Seat Heater

Thanks,<br /><br />The connectors under the seat are good and no chaffed wires.I just can't figure where the thing gets power from.Maybe a relay?<br /><br />DHP

With Toyotas, there is no better reference than the Factory Service Manual. I have one for each of my Toyotas, as well as several for Toyotas I used to own. They have complete schematics in the back. I would guess that there has to be a fuse for a system that carries other things on the circuit, so if nothing else is out, I would guess it's a relay. Toyota has relays for everything.

Re: Toyota Seat Heater

I agree about the manual.Does Toyota now put it all in one volume?Last time I bought them was in 1987,for a new Tercel 4wheel Drive SR5 wagon.I think the electrical manual was extra.Total then was about $65.00 or so.Maybe even another volume about emmissions.<br /><br />During boating season I won't even look under the hood of our vehicles,unless they don't start or move.I have people to that.The same people have me looking under the hoods of their boat engines.<br /><br />That's why I don't have the manual.All I need is a wiring diagram,or info from you guys if you've had this problem.<br /><br />DHP

Re: Toyota Seat Heater

I have checked the Toyota manual and the Alldata manual. No mention of OEM seat heaters. This may have been a optional dealer install. You will just have to trace the circuit from the switch. Look under the hood and under the dash for blown fuses...

Re: Toyota Seat Heater

Thanks Guys !<br /><br />I don't know how the dash switch could look so original,and not be factory.But I also respect what you are saying.And what you are saying is from areas I can't access,so I have to go along with you.BUT it sure looks stock. GRIN!<br /><br />The 1987 Tercel 4wheel drive was a great car.Being a 5 speed,it had actually 6 forward speeds in low range.Could pull itself out of a bathtub.<br /><br />DHP

Re: Toyota Seat Heater

If you have leather seats, the seat heaters are prolly factory. I have same thing in my 02 Sienna.Maybe dealer will pull it up on computer and print you schematic?

Re: Toyota Seat Heater

deej,<br /><br />Seat is definetily leather.Thanks for the tip,but while the local dealer has great people,he limits them on that type of 'free' help.But I will look into it.<br /><br />DHP
