Seat Warmers switch button

Mine are on the side too. It is a 3 way switch, flips up HOT middle OFF down LOW. I've gotten use to it. it is funny to watch the wife try to find that switch when she rides with me!

 

Yes, its Canadian, but I would not think Toyota would make 2 models different that much. More parts to cary as spares, 2 configurations, un economical.
Here is a picture of my "under console". You can actually the switch if you dig to the gear shifter level.


Wondering if I can just get the US- spec under Climite Control black panel with normal switches and swap. Does someone has a picture of the plug in US-spec Seat Warmer (non cooled)?

 

I’m pretty sure they are integrated into the AC module itself (which only has one plug going into it). I haven’t pulled mine to check.

But with that said, it might be possible to buy a used US limited-trim AC module and pull the lower trim panel and buttons out of it and rewire things back to the AC plug. Depends on how wiring-inclined you are.

And I don’t disagree on the though that it’s odd they do different components for up north.

 

That is so strange. Both on one switch? That's pretty dumb. I have a US Limited and the individual seat controls are under the ac controls, in between the temp knobs. I wonder if you could order the center control panel from an American Toyota parts supplier and make it work. You're going to have to dig in and see how that switch is sending that control circuit to both seats. Is that seat heater switch latching or do you tap it, like your ac controls?

 

It's not surprising there are 2 different wiring harnesses.
Good copper wire isn't cheap, no reason to have it there if the truck trim level doesn't have the features.
Its cheaper to manage the variations, than put material (and weight) into a vehicle that is un-necessary.

However, i think your heated seats were an aftermarket/ dealer add on for the following reasons:

1:The heated seat switch wiring loom wasn't routed with ANY of the other switches.
2: The coupler with the black and white lead is zip-tied back. This is the glass break security coupler. (mating switch has to be purchased seperately but it is clipped into a blank cover from factory.
Someone removed it from the blank and repositioned it.
3: OEM's don't use regular zip ties on harnesses. It's either fabric tape or electrical tape. When OEM's do use zip tie clips, they are never applied directly to wire coatings, there is always another barrier.

 

Not aftermarket. Its a factory option in the Canadian market. Straight from Toyota Canada website...

 

The fact it’s a separate loom could very well be because of the fact it’s an option only in Canada. So they run that wiring separate from the standard SR5 wire harness maybe?

 

There are some options that are installed at the factory level and other options that are port installed. Port installed options are items installed at a Toyota installation facility when the truck enters a country. Toyota know that the Canadian and American markets are different so the trucks are configured differently. For example mud flaps are standard in Canada on every model but an option in the US. Seat heaters are a port installed accessory. Some examples of dealer installed accessories are mud flaps, Toyota brand car starters and block heaters.

 

I was thinking this may be a port option as well.
Ruggy, you seem to be well versed in this breakdown, any career affiliation?

 

Dealer tech

 

I wonder why Canadians get fucked on the dash layout. Surely we use heated seats more than most Americans.

Also, a couple mistakes in this thread:

The SR5 Upgrade does not come with a moonroof in Canada.

There is a separate switch for the heater in each front seat. They're just stacked so they only take up one switch slot. Top section is the button for the driver's seat, then a piece of fixed plastic in the middle that isn't a switch but just has the seat heater symbol on it then bottom section is the button for the passenger seat.

 

I had a similar aftermarket heated seats installed on a 2018 SR5. At first, I thought it was wonky, but really it became second nature after only a few uses. Not much different than reaching down to adjust the lumbar support. I now have the factory setup on my 2020 and I have to look to make the setting correct. Advantages to both setups I guess, but if mine had the aftermarket setup already, I wouldn't change it.

 

Do the American-spec switches reset when the vehicle is shut off? Everytime I get in my truck, I have to grope for the switch to check that the passenger side wasn't left on. Feeling for the switch and thinking "F--- you, Toyota!" is a sort of ritual of using the truck in the cold.

A friend of mine has a 2009 Tundra from the USA, just loves his truck, and was mystified with my complaints about my truck. One day he went over my truck next to his. He went from saying "no man, you're gonna love this vehicle!" To saying and said "Huh... that's stupid. Why would they change that?" a few times when he found the seat heater switch, the rear seats folding up instead of down, and a handful of other differences I don't recall. I think he loved his truck even more by the time he was done, haha, no more FOMO.

 

Its a push switch which stays pushed in till you push again to turn it off. Its not a "momentary" switch like Push-Button Start button

 

Trust me, its factory. I took the truck from the delivery Hauler when it was all covered in plastic wrap inside. I was the first to open the door and it was there. Every single non-Platinum Tundra in Canada has exactly the same switch if it has seat warmers. So its 100% done by Toyota manufacturing plant in Texas.

 

Typically when vehicles are exported from US to Canada, they are shipped to a "port" then distributed from there through various methods including haulers.
These ports can and do add packages and options to vehicles. Ports also can repair defects that may have slipped out the OEM's door.
Repairing prior to getting to a dealer allows the factory to avoid dealer charge backs.
It sounds like you have a clear understanding of where Toyota applies regional packages and are aware of their shipping methods to Canada, so I will stop trying to educate you otherwise.

 

Can someone who has US-spec Tundra with just Seat Warmers (no-Cooling), open up the HVAC panel and take a picture of wiring behind it?
Also, is there a part number for Black plastic piece just bello the round knows which contain those US-spec buttons for Seat Warmers?

 

Personally, I don't care who at Toyota is specifically responsible for doing us dirty, in as much as finding options to mitigate the outcome. I like this intitiative to reposition the switch, though! The cherry on top would be if the seat heater switches could reset on vehicle shutdown...

Even a replacement switch that resets on vehicle shutdown, located in its unfortunate stock Canadian position would be a big improvement, for me anyway.

 

Even the US switches don’t “reset” - they retain the settings from when the truck was turned off. That’s why my ass is nice and comfy every morning when I get in.

 

The entire AC control unit is one part number from Toyota - it's not an option to buy just the lower bezel or the seat heater switches. It is different based on whether you have a CrewMax or a DoubleCab (because of the servo controls for the air vents in the center console of the CrewMax), and if you have a Limited or a 1794/Platinum (based on heat-only or heat/ventilated seats).

I see it has the same small plug as mine without Seat Warmer switches.
Someone would need to run a pin check, but my concern that it may be controlled by CANBUS and therefore its an ECU may need to be changed elsewhere...

 

Attached is the wiring diagram for a 2015 Tundra seat heater (US Spec). The wiring for these shouldn't be any different to the 2020+ so you're looking at the "A/C Amplifier" (which is the AC Control unit) being the unit that controls the seat heaters in the US Spec models. No CANBUS involvement.

Any of the wires marked with a (*1) are for the heated/ventilated seats and would not apply.

 

Reviving this thread... I'm hoping to relocate the seat warmer switch. I have a Canadian truck with the same switch as the op. I have a 3d printed 3 switch pannel behind my shifter. Is there any reason I couldn't cut the connector off the factory wire, and use a butt crimped connector to extend the wires?

 

It's an interesting option. No problem of relocating the switches.
Where are you in Quebec, Canada?

 

Originally from Toronto, now in Maniwaki. 1:40 north of Gatineau

 

Where did you find those switches? You been happy with them?

 

They came with the katskinz heated and cooled system. Very happy with them.

 

You know if they'll sell just the heated and cooled system without the seat covers by chance?

 

Put mine here

 

This is the person I would ask. I purchased everything through John
