If the taillight fuse blows, the instrument cluster illumination would not work. There is a shortin somewhere and if you have any impact damagges to fron ot rear of vehicle check the wirings for shorting to body. Disconnect all taillight bulbs and test if fuse still blows.

A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a 12 volt light bulb. A brake light bulb works well. When the circuit is live and the short is present, the bulb will be full brightness and hot so be sure it's not laying on the carpet or against a plastic door panel. Now you can unplug electrical connectors and move things around to see what makes the short go away. When it does, the bulb will get dim or go out.

Hope KHLow2008 can help with that. I've never been able to access the wiring diagram section. We do have links here for Mitchell service manuals. I can also send you to AllData if that will help.

Where exactly does #23 go. How many things does #23 power. Need to see some wire routing.

This link will take you to Mitchell Manuals:

This one will take you to my web site with an ad on top for AllData:

I have a lot of stuff for troubleshooting electrical problems but nothing specific to your car. Mitchell is less expensive and they have always had really good wiring diagrams. I wish I could get into those sites to get a diagram for you. Hopefully KHLow2008 will be able to when he sees your reply.

Are you sure the problem is in the back?

Did you check the front left side marker in the bumper?

How's the amber bulb in the front headlight assembly?
