We have had some issues with the radio shutting down in the past but it

always comes back on. Then on sunday we were on our way back from cali
and I jumped a bump a bump nothing seemed to happen -why would it this
is an suv right? Then about an hour later the radio (which is stock)
shut down, then the int lights stopped working, then when we took the
keys out the car still dings. so we checked the fuses and the relays
the int fuse was blown and when we replace it it pops instantly. The
relays are fine except the int relay is making a clicking noise when
you turn the headlights on. So I drove the car to the store and it ran
fine (just no radio or int lights) the next morning when I went to go
to work it wouldn't start!!! What has happened to my car? suggestions I

have heard is that it's  the voltage regulator or altenator or a plug
has came unplugged. PLEASE HELP ME!!!
