Default Driver Low Seat Warmer Doesn't Work

So the title says it all. My driver side heat warmer doesn't work on low but does on high. The light doesnt work either buy that's a none issue...I hope. I checked the connection under the center console and fuse and they were both fine. Any ideas on how to fix the seat warmer?

You can check for voltage at the heating element when it's set to low, if the voltage is missing then trace the circuit back to find where the break is. The light out at the switch could be related or just coincidence. If voltage is there the low element may be open, in that case it would have to be replaced.
Since there's an identical setup on the passenger side you can compare voltage and resistance readings between them.

It would be best if you had the factory manual with the wiring diagram so you can trace the circuit more easily.

Is bigger than yours.


Probably a broken element/wire in the seat itself. If there's power and ground at the seat connector, you know where the problem is.
