How technical of an answer do you want? The resistance of any fuse in any circuit should be negligible. If it is not, the circuit or the fuse is poorly designed. Of course there is resistance in the fuse which actually does matter, or else it would be able to handle an infinite amount of current without blowing from excess heat (I^2R losses). In circuits where very small resistances matter, there are other ways to deal with over current issues.

Can you replace a 30 amp fuse with a 15 amp fuse?
Not a good idea. The 15 amp fuse will be protection a #14 wire which is rated for 15 amps maximum capacity. By changing the 15 amp fuse to a 30 amp fuse you would then be allowing 30 amps maximum capacity on a #14 wire. By doubling the load the extra heat generated on the smaller wire could be enough to melt the insulation from the wire and that could cause the wire to short out. If the wire shorts out inside the wall it means the removal of the wall board to replace the wire to restore the circuit to an operational condition. The proper wire sizing for a 30 amp fuse is, #10 copper wire with an insulation rating of 90 degrees C.
What fuse is for cigarette lighter in 2004 Alero it has a 30 fuse in slot 34 but from what I have read it should be a 20 which is it?
A cigarette lighter fuse is normally a 15 or 20 amp fuse depending on what other accessories are using that circuit. I doubt that it is a 30 amp fuse. Maybe someone installed the wrong fuse.

Not a good thing to do! If you are blowing 10 amp fuses, you have a problem with that circuit. Putting a 30 amp fuse in its place can do more damage.
