Here's a New One For ya!

So... Started the Truck last night after a Night Flight. I had the door open while conversing with a buddy, maybe 1 minutes tops. Door stayed full open, while engine was running and my Interior ceiling light would dim OFF then come back ON. This happened probably 4 or 5 times, seemed like the bulb might be failing but then it would come back on full bright.

Light was set to door (not in ON, or OFF position)

Only electrical equipment i have messed with was while swapping out stock head unit with aftermarket head unit (accomplished March 11).

Battery was replaced September 11

This is the first time i noticed the slow flashing


any ideas???

PS

She's is a Stock 07' with 44K on her and will be paid off next month!

 

If you noticed no other electrical irregularities, then I would suspect either corrosion of the bulb contacts, or being loose. The next thing I would check would be the door switch and moving the dome switch back and forth a few times between positions.

 

Moved the dome switch to ON... and works as advertised

 

sounds ike the electronics are confused
