[quote=Amervo] What the heck good is a wiring diagram when you haven't taken the first steps of the most common failures.

What the heck good is it to rip into someone elses comment if they're just trying to help? Come on now, calm down. If you read what I wrote, I said that you look for a common fuse, etc, etc....

Fine, you want basic...uh... (1) check to see if the bulb is burned out (2) verify the contact surfaces of the bulbs and connections are clean and tight, (3) check to see if the bulb is put in correctly, (4) check to see if a fuse is burned out, ...and you keep sleuthing up to and including if necessary..(5) use the multimeter to check for power at the fuseblock.. (6) check between fuse block and power source (if no power anywhere), (7) check between fuse block and bulb connections for resistance (if power to block and elsewhere, but not that specific circuit), ...etc, ec..

All of those things will help narrow down the search for what is nothing more then a break in the electrical circuit. A break could be a burned out bulb, bad connection, broken wire, broken switch/or poorly adusted switch. And it could also include wires wired to the wrong circuits (cross wiring), etc...

btw: Last time I checked the forum was for us simple folks who are just trying to help. I never claimed to be a certified auto mechanic.
