no fuses blown, lights come on, both switches, but no heat?, they were working like 2 months ago, any ideas?

djmark7,

 

Under the seats are the wiring connectors for the seat heater of each seat. If you pull the connectors apart and turn on the switch, a test light placed on the two contacts for the wiring harness side (not the connector that goes up into the seat itself, but the one from under the carpet) should light up. If it does, your problem is in the heating grid and wiring under the seat covering (leather or cloth).

 

If the test light doesn't come on, your problem may be a relay for the seat heaters, a fuse, or the switch itself.

 

If we knew the year and model of your car, someone might even be able to post the FSM diagnosis chart for you.

His profile says '98 Legacy wagon.
