DIY: Repair Seat Warmer
#28
Hey dodgingwrenches... did you ever figure your issue out? I have the exact same problem. Both seats don't work. I intend to rip them out and see if it's a lose wire... but... interested if you have an update before I start.

I had the same problem and I did rip both seats out and tear apart the cushions. Only to find all connections working and no breaks in the heating elements.
Come winter they started to work again.
I think it may have to do with what temp the car is reading outside?
Who knows, all I know is the seats do not get warm enough.
My T & C Chrysler gets real warm and my RX8 only gets luke warm.

Sorry for bumping an old thread... just want to re-check...
so the thing that is warming our seats are just thin pieces of wire? not a big heating module that i can remove to save weight??

Its a pad, and only weighs a couple ounces. I'd only remove them if you're targeting ultra light wight and need to sweat the ounces. removing the plastic engine cover will save you more and not take all day to do.

1. Blown fuse. Always check these first.
2. Loose/dirty switch contacts. Pull off center console cover, disconnect, clean. Also check the connections under the seat.
3. Broken wire. This will be harder to diagnose.

So just a quick question. I don't have heated seats in my RX8 that i know of. When i did my navigation install in my S2 RX8 i found that under my dash panel from the shifter to the cup holders there were the 2 plugs that i assume connect to the heated seats switches. Does this mean that i have headed seats and Mazda Wired it up bust just left the switches out because i did not order that feature?? MMMMMMMm
I will post a pic when i get home from work. I didn't drive her today i drove the truck

I'm a big fan of seat warmers bc I have back issues... Yes I live in Florida where the temps here in the car can easily reach 110f. So if the tstat breaks at 99, I may not have a seat heater issue at all eh? Perhaps my body + car temp > 99? Looks like I'm going to have to fool the tstat
PS Thanks for the writeup! This has helped a bunch!
Hej da!

Sometime over the summer my seat warmer gave up and quit working. Well with the temps around 0 F here in Sweden now I decided to take the seat out and look at it. Yes my car is a normal NA 04. My problem was on the drivers side, but it might also apply and help for the passenger side too.

Thanks for posting this fix and diagnostics steps. Mine turned out to be the exact same problem, with both lower heater wires severed by the rod they cross under. I figured new wire will be just as susceptible to breaking there, given that poor layout choice, so I cut out the middle section of the rod to extend their life.
The heater functions now (yay!), although it seems to be quite weak, as some people have reported. The car (a slow-warming V8) is almost up to operating temperature by the time the seats are warmed to 70 degrees in sub-40 degree weather, at which point the heat in the car makes them largely frivolous. At least I know the wiring and everything works, so I have the option of putting in stronger aftermarket heaters in the future.
Oh, and I discovered that it's not necessary to disassemble anything on the seat to address the lower heater pad. Just unclip the two side flaps and rear flap below the seat pan. That gives enough slack to the seat cover to pull it up in back and access the wires.

There appears to be some instructions missing between posts #3 and 4, but I realized while removing the side trim that it was unnecessary to disassemble anything further.

seems like no one ever answered this, and in case anyone finds this by doing a search, the answer is that those switches contain tiny but replaceable light bulbs. Idk what the official Mazda bulb is there, but I had some extras from my Honda, 7219, that work just fine. Can’t remember where I got them, but pretty sure amazon has them.
