The instrument cluster in my 2005 Mountaineer has been randomly "failing" for about 2 months. By "failing", I mean the gauges will go to zero and bounce, the dash lights will go on and off, and the radio will go out. The car will continue driving normally. Headlights stay on, windows work, cruise works, interior lights work. This random event lasts about 4 seconds.
It may do it again within minutes, or not again for the day. Sometimes, when I open the car door to get in (keys not in ignition), I will notice the gauges are bouncing at the zero mark.
I took it to the shop, but of course it didn't do it there. They checked the alternator and battery. Battery is old, but checked out.
A few weeks later, complete Alternator failure. Replaced the battery and alternator and I hoped that would solve the dash issue, but it did not.
I've had it to the dealership, and to an independent, and their not sure what's up with it. The code readers give no insight.
Has anyone every had this issue?
I've seen the issue online, but never with an answer. I've seen people post videos of it online, bet never a solution.
My next step is to do an old fashioned ghost hunt in the car.
