The rear window defroster went out this week. When I press the button, the indicator lights up but I don't hear the click of the relay that I normally did. I consulted the manual to locate the fuse relay and it says it's under the panel on the left hand side of the dash.
No problem, I figure I would pull the module and start doing some voltage checks. Well, I pulled the panel off and found the upper portion of the diagram and all of the fuses line up with what's shown. However the bottom part of the diagram shows another bank of fuses and relays. However in my car there is a wiring block where the relays should be. There appears to be single 8mm nut holding it down but I didn't want to pull it off for fear of messing with something I shouldn't.
