Intrument lights flash intermittently
Hey all,
I have a 97 F150 5.4 4x4.
The other night I noticed that all of my instrument lights intermittently will dim just a little every 5 seconds for a split second or so and come back. It IS rhythmic but I can't pin point it to a misfire or a change in engine noise. And its every light, instruments, climate control, window/lock switches ect.
Another thing that I am not sure if its related but never noticed it before is that when I turn my key to the run position before starting it, my OD light VERY quickly flashes just once.
Is this all part of a bigger picture? I want to nip it in the but before it becomes a bigger problem.
Thanks, Dylan
