My Interior lights in my car keep flickering and going on and off.?

A lot of bulbs simply get hot (incandescent), if it was your fuse, it would be blown or not, and its not. Could be as simple as the bulb isn't seated properly to loose connections in wiring or bad/loose ground.

Two things I can think of: Ford is notorious for bad door ajar switches. Could be that the switch is jostling between open and closed, which would activate the interior lights (as if you were opening and closing the door). Second, all of the interior lighting is controlled by a single computer. A loose connection at the computer or short in the wiring could also cause the interior lights to act up.

it extremely is maximum probable the Alternator yet ought to doubtlessly be the bcm (physique administration module)...or the two. replace it with a DENSO or DELPHI alternator (used or new) or something rebuilt domestically. bypass to a areas save and notice what different aftermarket producers exist for this vehicle. or you will would desire to easily take the alternator off and have it custom rebuilt. BMWs have those electric powered issues simply by fact they use bosch electronics that are undesirable. fixing this issue assumes that bosch may even make a first rate electric powered harness which...could no longer be the case.

What happened with your car? I have a 2005 Ford Freestar with the same problem (2017)

clean the battery connections real good and shiny and make sure they are very tight.
