Question about 2003 Mercury Mountaineer
On a very cold nite( about 8 degrees) I turned the key and noticed that the automatic headlight switch wasn't working. Then i noticed that the instrument panel guages, interior lights, sunroof, SRS, radio, info center, power windows, garage door opener, etc didn't work either. Thank GOD the heat and blower fan still works! Any ideas? Power distribution block looks good. Is there one fuse or relay that provides power to so many things? Oh and things that still work are: directionals, hazards, horn, power mirrors, and power locks
Have the battery tested, perhaps the alternator also. I had the same problem on my 2005 Taurus ( also a Ford / Mercury product ). I replaced the alternator easy enough, and a full charge on the battery solved the problem. The vehicles are designed to shut down unnecessary or non-vital accessories first, as to prevent a major shutdown on the road. So your lights and signals will still work, but the rest of the electrical will power down to conserve the battery.
You can get the battery tested at most service stations or you can buy a tester at any auto parts store. Some of them will test it for free.
Hope this helps.
