1999 Grand Marquis: instrument cluster..The speedometer

Resolved Question:

The instrument cluster in my 1999 Grand Marquis is not functioning. The speedometer, the battery gauge, and the temperature gauge are not working. ? I checked the fuses and noticed that the 15 amp fuse in the number 13 fuse location was blown. I replaced it and it blew again. What can be causing the fuse to blow and is that the reason the instrument cluster is not working?

Hello and welcome to Justanswer,
My name is XXXXX XXXXX I am here to assist you with your question.

The cluster fuse is the #13 and if its blowing its eaither because the cluster is internally shorted or the lighting control module has failed. In most cases its cause by a failed cluster. I would start with unplugging the cluster and see if the fuse holds. If so, then the cluster has failed.

I am not a mechanic, so I need a little more help. How do I unplug the cluster? Should I have a mechanic do this? Is it easy to see where the cluster connects to the fuse box?
Expert:  Ron replied 6 years ago.
Yes that would be best because to unplug the cluster it will have to be removed. Once the cluster is removed, you will see the connector easily.
