Seat heaters and electric seats stopped working. Could this be associated with a fuse problem?

There is an electrical connector underneath the seat. Verify it is connected. If it is connected, check the fuse (find fuse location underneath fuse box lid). If those two check out, check the voltage at the electrical connector underneath the seat with the heat switch on. Other possibilities include a broken wire inside the seat. If one of the heater wires is broken inside the seat there will be no continuity and the heat will not work.

Do both your front seats have heaters ? Do both not work , or just one ? Do the heated seats have heat elements in backs as well as the seat ? The heater grid in the seat go bad !

Check the heater fuse, if the fuse is ok then the element need to be replaced

Ok I don't know who these people are giving advice but I hope they are not gm mechanics. There is a fuse under the hood marked MBEC 1 50amp. If it blows it knocks out both power seats seat heaters and power windows passenger side front and back. I can't believe all this wiring ****!

Sounds like you may have an electrical issue possibly. Have you checked your fuse for the seats? Your needle may be getting stuck or you could have a loose wire in the dash also.

Check with your local dealer or call me at 904-322-5150 my name is Adam. There may be an open recall that will solve your problem.. If so it can be fixed at no cost

Both seat heaters in this car are on the same fuse and relay. If one is working and the other is not, you can assume that the fuse and relay are okay. It could either be a broken circuit in the seat heater itself or a bad switch. Most likely it is a break in the heater element. I had this problem in my 2004 forester on the driver side. after removing the upholstry cover on the seat and some careful inspection I found two broken solder joints at each thermostat in the seat heater element. A quick solder job fixed the problem. The only real difficulty on the job was that the thermostats and associated connections are sandwiched between two layers of fabric and filled with hot glue. Careful probing with the end of a soldering iron can melt the hot glue away from the areas you need access to. A quick internet search will find you some pretty good directions on how to remove the seat covers. Hope this helps.

renew the whole unit behind the radio facia ,same as seat radio goes haywire and heater controls pack up and its expensive but easy to change with only one multiplug
