2017 Toyota Tacoma Seats Problems

Your driver's side heated seat isn't working—when you turn on the heated seat switch, nothing happens. Upon inspection, the electrical wiring and connector that powers the seat heater have melted and been destroyed, which is why the heating elements won't function. Toyota is aware of this issue and has published a technical service bulletin about it, but the dealer hasn't offered a fix yet. Repairing this will likely involve replacing the damaged wiring harness and heating element assembly for the driver's seat.

I had noticed my heated seat stopped working. Upon investigation and searching the web for similar issues I found that a relay for the seats located under each front seat was the issue. I saw pictures online of others and when I pulled my seat out I found the connection between the wires and relay had been completely burned and melted. This is Toyota part number 87501-0C020. When looking up this part it is discontinued with no replacement. There’s no recall or warning from Toyota for this issue. This same part is also installed on Tundra too. By the amount of burning this is definitely a safety issue and I don’t know why it has not been addressed.
