Folks, the heater in my old Valiant hasn't worked in a few years. Specifically, if you hook up the heater relay, the fuse blows. The relay is on top of the heater box.
If you run a jumper wire under the hood to the heater fan, it turns on and works fine.
I've used an ohmeter on the relay, but I don't know what kind of resistance I should be getting across it. It looks like it's just a coil of wire, is that right?
I'm thinking maybe I've got something else going on somewhere else, though that gets connected together if I plug in the heater relay.... if I leave it unplugged, the fuse doesn't blow.
any suggestions on how to systematically figure this sucker out? Or do I just likely have a bad relay?
66 Valiant, btw.
