Massage seat switch in 2019 Toyota GT86 no longer works.

Hey, so I had a similar issue with my 2016 Toyota GT86, I had a faulty cable connection/plug which caused various elements in my car, including my massage seat, to not work properly. At my last workshop visit, they checked this connection and found that it was indeed faulty. Honestly, this was a pretty serious problem because it affects so many things. They had to replace the faulty connection, which took a while, but after that everything worked perfectly again. So it could also be the cable connection or the plug in your case. I hope this helps you!

Hey, thanks for the tip! Sounds like we might have a similar problem. Do you happen to remember how much it cost you when you had the connection changed? I'm really curious to see how much it will cost me. And have you noticed any other problems since then, or has everything been running smoothly since then? Thanks again!

Sure, no problem! So replacing the cable connection cost me 95.0 euros. So it wasn't too expensive. And since then everything has been working perfectly. The problem with the massage seat switch was also fixed and everything has been working perfectly ever since. So, if you notice similar signs, you should definitely have it checked. Hope that reassures you a little!

Great, thanks for the info! 95.0 euros sounds perfectly fine to me. I'm relieved to hear that everything is back on track with you! That definitely gives me some peace of mind. I will contact my garage this week and ask them to check the cable connection. Thanks again for the help and tip!

Hey! It sounds very frustrating that your massage seat stopped working. I would say it could be the switch or wiring. Have you checked the fuse yet? Anyone else experienced this issue with their GT86? What did you do to fix it?

Before you take your car to the garage, you can check the fuse for the massage seat. It's a simple check that you can do yourself. If the fuse is blown, replacing it might solve your problem. If the fuse is fine, then it's likely a problem with the switch or wiring, as you and KarlH20 suspected.
