My rear window defrost all of a sudden quit working and and I have tried replacing the defrost switch to no awail. I have also checked that the wire teminal tabs are still connected to the window and have continuity between them. When I asked the guy at the subaru dealership parts department if there is a relay or something he told me that there is a timer on the car that should be in the vicinity of the passenger side dash area or maybe on the engine side of the firewall. Yet now you are telling me that there is no such part, I don't mind accepting your answer but I feel like I am getting conflicting information.

Thank you very much for your help. I know that parts dept. guys are not technicians (though if they work at the dealership I would still think that they should know what they are talking about). At least now I know that there are relays, though I still don't know where to find them. You have at least answered my question on the timer and then some, so I will gladly accept your answer. Now I just need to track down these relays.

Thanks
