Today I've been working on installing heated seats for my passenger princess. I'm installing a set of
Clazzio seat heaters with the Toyota-style hi/lo switches. It's been adventures in upholstery to get the covers off the seat, slide the seat heaters into place, and then wrestle the covers back on. I don't have a hog ring pliers so instead I've used zip ties to connect the rods back together under the covers. It works surprisingly well.
One thing I don't like about the Clazzio seat heaters is that I can't use the rear cross rod on the seat bottom fabric. I've left it in place but not connected to the cushion underneath. We'll see if that was a mistake or not (should I have removed it completely?) after a few months of use. It might break the heater filaments or it might be annoying to sit on. If either is the case, I'll pull the seats out of the truck again and fix them. But I'm hoping it'll be okay as-is.
If you are installing seat heaters,
watch this video. It'll answer 99% of your questions.
I first bench tested the heaters and electrical harness/switches to make sure everything worked.
Then I removed the passenger seat and got to work. My truck appears to have the harness wires for heated seats although I am not using the wires.
Pro-tip: remove the headrest before you remove the seat from the vehicle. It makes it a bit easier getting it in and out.
Lots of wires everywhere under these seats. Getting the fabric cover off is a bit of a PITA. You've gotta roll the clips off.
On the passenger seat I did disassemble the airbag side of the seat but on the driver side I figured out that I didn't have to. If you're dexterous, you can get the seat heater up in between the seat cover and the cushion by only removing the non-airbag side of the seat. That'll save you a bunch of time. Also you don't have to fiddle with the airbag.
This is as far as I removed the seat cover on the passenger side. I didn't bother pulling it all the way off. Someday I might replace these seat covers.
Here you can see those two cross bar things attached to the seat covers. The rear one does not get reused with the Clazzio seat heaters. On the front one, I cut some slits into the fabric holding the cross bar in lace at either end so that I could slip it under the seat heater.
This is looking under the seat back cover. You don't have to remove that upper cross bar with the Clazzio seat covers but I didn't know any better for the passenger seat.
Here you can see the lower seat cover in place. I cut a slit in the heater where there's a blank spot specifically to do that. Be careful to not cut the traces on either side of that blank spot. Then I used zip ties instead of hog rings to get the upholstery back into place.
Here's the passenger side all buttoned up. I taped the two seat heater connectors together and attached them to another cable in the middle of the seat (look for the two white connectors).
All done with the passenger seat. I think it looks about 9/10 compared to the factory 10/10.
NOW!!! ON TO THE DRIVERS SIDE!!!
I did have to remove the airbag cable (yellow) on both seats to get the covers off. Also when you get ready to pull your drivers seat, run the seat forward pretty far. There are some screws you need to access on the trim that are hard to get to if you have the seat pushed back like I normally do when driving.
The drivers side on my truck has power controls. They do get in the way a bit and you have to remove a bunch of stuff to be able to take the covers off. It's also a PITA to get the covers back on because of the extra doodads.
The seat controls pop off easily using a trim tab tool. I have laid them out in the correct orientation. On the small control, the larger straight opening goes up. On the long control, there is more void space pointing up. So in other words, just flip these over 180 degrees to the right or left and stick them straight on the control stalks. The lumbar button does NOT need to be removed.
After the trim comes off, then you need to remove that switch assembly and set it aside.
Here's a close-up of the cables and such.
Here's the routing for the drivers side airbag cable.
It looks pretty much the same on the driver side as it did on the passenger side. The only real difference is how the covers clip on. There are some extra clips that are annoying to remove and reinstall.
Then the next thing to do was remove the center console and open the dash up to bring the seat heater cables up to the center switch panel and install the switches. And wow there's a lot of dash to remove to do all of this!
Here's the last time my dash was still factory assembled
Here's the Qi wireless charger. It's not the best charger. Hopefully someone makes a replacement for it eventually.
The center console removed.
Here's one of the many computers on this truck.
Taking more plastic off. It's a PITA to get the glove box out.
More to come in the next post... I hit the 25 photo limit on this one
