    Replace bulb and see what happens. Then look for obvious shorts. Check switches. Measure resistance of circuit with and without bulb to isolate if before or after bulb

    Did you figure this out yet?

    My dome fuse keeps blowing as of 3 days ago.
    I can replace it, and everything works fine, but it eventually blows again by the next day.
    My alarm keeps going off when the fuse is good because it thinks a door has been opened.
    But when the dome fuse is blown, the alarm doesn't go off.

    I've got aftermarket interior LEDs in stock fixtures, LED footwell lights, and LED puddle lights, on that circuit, but it has been working just fine for several years...
    The only thing that has changed is the single digit temps we had at night the last few days.

    Merry Christmas...
