Ok for no aparent reason my heaters stoped working, I tried to see if it was a blown fuse but all were fine in the drivers fuse box, dont know about the ones in the engine room but I dont think the fuse is out there. Any one here has had the same problem? Any ideas? Where is the fuse located?:(

hmm take it to the dealer, shouldnt have any reason for a brand new one to stop working just like that...

The seat heater fuse is under the extra relay strip - that is just inboard of the main inside fuse box - you need to remove the lower dash cover to access it.

I have a 03 WRX and all wiring to the seats and the heater unit is present but I cannot find the plug/relay for the switches. When I bought the car the switches were not there (they were replaced with cheap aftermarket switches for amp and lights). I am certain the heaters will work if someone could please help find where to plug in a switch. Do the switches have pig tails or does the harness plug into the switches? Any help is appreciated.
