The relay is in the engine compartment fuse box behind the black panel on the driver's side. I don't have a pic handy but I want to say it's the left one. Searching for other threads on autoheat will find you the pics, although I don't know of a way to troubleshoot the relay other than jumping it to see if the footwell blowers work (again, use search for this).

Cheers for that wrxnofx
