[/URL][/IMG]s I'm trying to figure out why my rear defrost and heated mirrors won't work. I've narrowed it down, but need a picture of the wiring diagram on page 10-8 of a service manual for an 03 excursion. It's c241 on the bottom left side of this diagram. Just to tell ya I've made sure my 40a fuse is good, relay is good, and switch is good. What it's not doing is sending a ground signal to the relay to activate it when rear defrost button is pushed. I have 2 03 excursions, so I tried swapping GEMs, fuse boxes, relay, and switch to make sure they work... Damn wiring!
