Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hi. I work at a Ford dealer and this fuse to blow on the Milan is not a common problem. Fuses almost always only blow when something has shorted. So without finding the cause then it would say it is likely that it will happen again. That does not mean it will, but I would consider it likely.
You are paying for a chat. The only way to prevent this is to find what shorted. Unfortunatly it is not easy, and near impossible to find a short that is only intermittant.
At this point, you can really only perform a visual inspection of your cars wiring to see if you can find a problem. When the short is constant and blowing the fuse immediately the short is much easier to find.
Since it is the ignition switch fuse the wiring I would inspect would be the wiring under the steering the column. Do you have a remote start installed?
That would be the first place to start looking for a short. Remote start wires need to connect to ignition wires. A wire could be routed near something metal and shorted.
What about my responses are you not getting the info you want?
