Obviously a blown fuse ! Bring your a*s to R&S or Pepboys and get the manual for your car ! Its gonna be a 10 amp fuse (2.00 at Pepboys) but consult the manual to find out where it goes...Or if you dont have money for the manual, you can do it the crude way....go through all of the fuse by pulling each one out, and then putting them back in.........the blown fuse will be easy to spot; each fuse has a little metal "strip that you can clearly see in the middle of it. When a fuse is blown, the metal strip is broken (look for a little burnt spot in the middle of the fuse). Find the fuse withthe broken strip, and that is your radio/clock fuse !
